As everyone knows, not only between WDM equipment and customer equipment, exist a large amount of optical fiber to connect, and also exist a large amount of optical fiber to connect between the functional unit in WDM equipment, wherein, between the equipment or the optical fiber between the functional unit in the equipment connect to be to connect and to realize by the optical fiber between the light mouth of equipment or functional unit.According to statistics, quite a few fault on the existing optical-fiber network all occurs in optical fiber and connects, if judge it is that faults such as unusual take place which root optical patchcord by the annexation between the light mouth, then extremely helpful for the problem that solves optical-fiber network operation maintenance existence, therefore, how to determine that the problem of the annexation between the light mouth is extremely urgent.
At present, those skilled in the art have proposed a kind of optical fiber and have connected automatic discovering method, promptly, all embedded mechanical induction installation in the ring flange of each light mouth in the functional unit of all band light mouths of optical network node, when optical patchcord is inserted into ring flange, functional unit can detect optical patchcord by mechanical induction installation and be inserted into the light mouth of oneself, afterwards, functional unit can report optical patchcord to insert incident to the control unit or the network management unit of optical network node, control unit or the network management unit optical patchcord of writing function unit again insert incident, thereby find the interconnection each other of light mouth.In this method, light mouth correlation rule by pre-configured control unit or network management unit, can find the interconnected relationship each other between the light mouth, for example, under man-to-man rule, two light mouths that link to each other report optical patchcord to insert incident, think that promptly these two light mouths link to each other, and under the rule of one-to-many, first light mouth that reports optical patchcord to insert incident is regarded as the key light mouth in the one-to-many, and the light mouth that after this reports optical patchcord to insert incident is considered to from the light mouth, thereby determines the key light mouth and from being interconnected relationship between the light mouth.
The inventor passes through serious analysis, scrutinizes the back discovery, said method no doubt can be realized the automatic discovery that optical fiber connects, but, this method requires relatively stricter to the attended operation personnel, that is, requirement must be inserted optical patchcord in order could find annexation between the light mouth, but in practical operation, the Operation and Maintenance personnel unify operation to all light mouths of a veneer often, if according to annexation the light mouth is operated and can be had big difference with existing operating habit.And when the existing man-to-man situation of the optical fiber connection relation between the light mouth, when again the situation of one-to-many being arranged, control unit or network management unit be switching working mode ceaselessly, otherwise erroneous judgement may occur.So this method still is the control unit of optical network node or the problem that all there is inconvenient operation in network management unit for the attended operation personnel, is difficult to use in practice.

Embodiment
Below we will be in conjunction with the accompanying drawings, several embodiments of the present invention are described in detail.
At first need to prove, method and apparatus of the present invention both can be used for determining the annexation between the light mouth of optical network node, also can be used for determining the annexation between the light mouth of each functional unit in the optical network node, both can successively carry out, also can carry out simultaneously, wherein, each functional unit in the described optical network node can be the optical network device functional unit.
Definite method of first kind of connection relation between optical interfaces provided by the invention can comprise the steps: on each light-emitting window of optical wavelength signal or optical multiplexing section signal process described optical wavelength signal or optical multiplexing section signal loading to be identified, and the sign to described optical wavelength signal or optical multiplexing section signal loading on each light inlet of described optical wavelength signal or optical multiplexing section signal process detects; According to the result of label detection, determine the annexation between light inlet and the light-emitting window.
Wherein, can determine annexation between light inlet and the light-emitting window according to following step: according to the result of label detection, by the detected light-emitting window sign of described light inlet quantity from few ordering at the most; If have a light inlet only to detect the described sign of a light-emitting window, then determine to have annexation between described light inlet and the pairing light-emitting window of described sign.
Further, if certain identifies between the pairing light-emitting window and has annexation in identifying with described n to have determined to detect the light inlet of n sign, then determine to detect between n+1 light inlet that identifies and the pairing light-emitting window of detected different sign and have annexation, wherein, have n sign identical with the detected n of light inlet sign of the described n of detecting sign in described n+1 the sign, n is the integer greater than 0; By that analogy, and then can determine annexation between other light inlets and other light-emitting windows.
Below in conjunction with Fig. 1, first method provided by the invention is elaborated.As shown in Figure 1, comprise the steps:
Step S101: each light inlet determines may have the light-emitting window that is in the upstream of annexation with it.
Light inlet detection and its mode that may have the light-emitting window of annexation have a variety of, illustrate below.
Can be on each light-emitting window to optical wavelength signal or optical multiplexing section signal loading sign, the mode that loads can be that while or timesharing load, described sign can be corresponding one by one with light-emitting window, and id information that frequency, spreading code, the sign that sign is adopted is entrained or sign time slot corresponding information also can be corresponding one by one with light-emitting window.
Optical wavelength signal or optical multiplexing section signal can carry a plurality of different signs by behind a plurality of light-emitting windows.When carrying the optical wavelength signal of a plurality of different identifications or optical multiplexing section signal and arriving certain light inlet, this light inlet can carry out the beam split detection to optical wavelength signal or optical multiplexing section signal, the sign that demultiplexing is all, if the demultiplexing result is bigger than system determination thresholding, then can determine the light-emitting window that may have annexation with this light inlet.Need to prove, because optical wavelength signal or optical multiplexing section signal can be through arriving certain light inlet behind a plurality of light-emitting windows, and each light-emitting window of process can be loaded into different signs on same optical wavelength signal or the optical multiplexing section signal, so, this light inlet that receives optical wavelength signal or optical multiplexing section signal can detect a plurality of light-emitting windows, but is not that each light-emitting window all has annexation with this light inlet.In theory, each light inlet can both detect all light-emitting windows at its upstream, but, if at the upstream light-emitting window to the functional unit that has wavelength selectivity between the described light inlet, then described light inlet might not detect the upstream light-emitting window, for example, if the amplifier of upstream is through a wavelength selectivity interleaver (WSS, Wavelength Select Switch) is connected to the another one amplifier afterwards, and WSS optionally switches the wavelength signals of transmitting between two amplifiers, then the amplifier in the downstream light-emitting window of the amplifier that detects the upstream surely that just differs.Therefore but, insensitive because optical fiber itself is wavelength, between the light-emitting window and light inlet at optical patchcord two ends, light inlet is sure to detect corresponding light-emitting window, and therefore, above-mentioned restriction does not influence the judgement of light mouth annexation.
Step S102: with each light inlet and its detected may and its corresponding relation that has between the light-emitting window of annexation gather.
Each light inlet can report the light-emitting window that has annexation with it after determining to have the light-emitting window of annexation with it, certainly, and optical network system also can initiatively have annexation to each light inlet inquiry with it light-emitting window.In addition, after corresponding relation gathered, can also corresponding relation be sorted, for example according to from less to more order according to the quantity of the detected light-emitting window of each light inlet.
Step S103: the corresponding relation of selecting the only corresponding light-emitting window of a light inlet.
In general, if only corresponding light-emitting window of light inlet, can illustrate that then this light inlet and this light-emitting window have annexation, so, if at first select the corresponding relation of the only corresponding light-emitting window of a light inlet, then the annexation of a light inlet and a light-emitting window be can determine earlier, thereby some light inlets and light-emitting window got rid of for follow-up definite annexation.
In addition, after gathering corresponding relation, the corresponding relation of an only corresponding light-emitting window of light inlet has a plurality of, at this moment, when selecting the corresponding relation of the only corresponding light-emitting window of a light inlet, can select a light inlet and light-emitting window corresponding relation one to one at random, certainly, also can select corresponding relation one to one, for example the descending sequential scheduling of number of times that in the corresponding relation of other light inlets, occurs according to the light-emitting window in the one-to-one relationship according to certain condition.
Step S104: have the corresponding relation of this light-emitting window this light-emitting window deletion from other.
If have this light-emitting window in other corresponding relations, promptly, other light inlets are corresponding with this light-emitting window, though then can determine this light-emitting window is the upstream light-emitting window of these light inlets, but not the light-emitting window that has annexation with these light inlets, what have annexation with these light inlets should be other certain light-emitting windows in the corresponding relation, so, if after determining the annexation of a light-emitting window and a light inlet, then this light-emitting window from having the corresponding relation of this light-emitting window, other can be deleted.
Step S105: judge whether also to exist the corresponding relation of the only corresponding light-emitting window of a light inlet, if return step S104, otherwise change step S106.
Step S106: judge whether to exist the light inlet that does not have corresponding any one light-emitting window, if change step S107, otherwise finish.
Step S107: determine that described light inlet is not connected with any light-emitting window.
Need to prove, in step S101, if certain light inlet does not determine that any one light-emitting window may have annexation with it, then can determine following situation: first kind of situation according to the classification of this light inlet, if light inlet is the light inlet of optical network node and needs to determine may have the light-emitting window of other optical network nodes of annexation with it, can determine that then this light inlet does not have to have annexation with the light-emitting window of any optical network node; Second kind of situation, if light inlet is the light inlet of certain functional unit in the optical network node and needs to determine may have the light-emitting window of other functional units of annexation with it, can determine that then this light inlet does not have to have annexation with the light-emitting window of any functional unit.In like manner, if certain light-emitting window is not detected by any light inlet, then can determine following situation: first kind of situation according to the classification of this light-emitting window, if light-emitting window is the light-emitting window of optical network node and needs to determine may have the light inlet of other optical network nodes of annexation with it, can determine that then this light-emitting window does not have to have annexation with the light inlet of any optical network node; Second kind of situation, if light-emitting window is the light-emitting window of certain functional unit in the optical network node and needs to determine may have the light inlet of other functional units of annexation with it, can determine that then this light-emitting window does not have to have annexation with the light inlet of any functional unit.In addition, if certain light inlet does not determine that any one light-emitting window may have annexation with it, perhaps certain light-emitting window is not detected by any light inlet, may illustrate that then the optical patchcord that is linked into this light inlet or light-emitting window breaks down yet.
Also need to prove, in step S101, can on each light-emitting window, load sign simultaneously to optical wavelength signal or optical multiplexing section signal, also can timesharing load sign, for light inlet, as long as detect the existence of sign at the appointed time, can determine that this identifies pairing light-emitting window at its upstream.But consider that sign may have certain interference to optical wavelength signal or optical multiplexing section signal, if a plurality of signs are loaded on optical wavelength signal or the optical multiplexing section signal simultaneously, can produce bigger interference to optical wavelength signal or optical multiplexing section signal, so, if optical wavelength signal or the timesharing of optical multiplexing section signal are loaded sign, in the time of then can avoiding determining light mouth annexation optical wavelength signal or optical multiplexing section signal are produced excessive interference and cause error code.
In addition, step S106 and step S107 can carry out behind step S101, S102 and S104.
More clearly understand flow process shown in Figure 1 for ease of those skilled in the art, enumerate the embodiment of two practical applications below, again flow process shown in Figure 1 is described.
First Application Example is used for determining the connection relation between optical interfaces of optical network device functional unit.Suppose that certain optical network node comprises functional unit A, functional unit B, functional unit C and functional unit D, each functional unit comprises light inlet 1, light inlet 2, light inlet 3, light-emitting window 1, light-emitting window 2 and light-emitting window 3, certainly, the light inlet quantity of each functional unit can be inequality with light-emitting window quantity, the light inlet quantity of each functional unit or light-emitting window quantity also can be inequality, here for convenience, suppose that quantity is all identical.
After each light inlet detected and may have the light-emitting window of annexation with it, gathering each light inlet and its, may to have the corresponding relation of light-emitting window of annexation with it as follows:
Figure GDA0000066627390000081
Table 1
As shown in Table 1, the light inlet 3 of the light inlet of functional unit A, D and functional unit B does not detect any light-emitting window of any functional unit, this can illustrate that the light inlet 3 of the light inlet of functional unit A, D and functional unit B does not have to have annexation with any light-emitting window of any functional unit.
After making up table 1, the corresponding relation of the light inlet 1 of selection function unit B and the light-emitting window 1 of functional unit A at first, because this is a corresponding relation one to one, has annexation so can determine the light inlet 1 of functional unit B and the light-emitting window 1 of functional unit A.
The light-emitting window 1 of functional unit A is deleted from other have the corresponding relation of light-emitting window 1 of functional unit A, and in table 1, the light-emitting window 1 of functional unit A does not occur in other corresponding relations.
The corresponding relation of the light-emitting window 2 of the light inlet 2 of selection function unit B and functional unit A because this is a corresponding relation one to one, has annexation so can determine the light inlet 2 of functional unit B and the light-emitting window 2 of functional unit A again.
The light-emitting window 2 of functional unit A from having the corresponding relation of light-emitting window 2 of functional unit A, other is deleted, in table 1, has only the light-emitting window 2 of the light inlet 1 ability corresponding function unit A of functional unit C, so the light-emitting window 2 of functional unit A is deleted from the light-emitting window set of light inlet 1 correspondence of functional unit C.
The corresponding relation of the light-emitting window 3 of the light inlet 1 of selection function unit C and functional unit B because this is a corresponding relation one to one, has annexation so can determine the light inlet 1 of functional unit C and the light-emitting window 3 of functional unit B again.
The light-emitting window 3 of functional unit C is deleted from other have the corresponding relation of light-emitting window 3 of functional unit C, and in table 1, the light-emitting window 3 of functional unit C does not occur in other corresponding relations.
The corresponding relation of the light-emitting window 2 of the light inlet 3 of selection function unit C and functional unit D because this is a corresponding relation one to one, has annexation so can determine the light inlet 3 of functional unit C and the light-emitting window 2 of functional unit D again.
The light-emitting window 2 of functional unit D from having the corresponding relation of light-emitting window 2 of functional unit D, other is deleted, in table 1, so the light-emitting window 2 that has only the light inlet 2 ability corresponding function cells D of functional unit C is the deletion from the light-emitting window set of light inlet 2 correspondences of functional unit C of the light-emitting window 2 of functional unit D.
The light inlet 2 of last only surplus next functional unit C and the corresponding relation of the light-emitting window 1 of functional unit B have annexation so can determine the light inlet 2 of functional unit C and the light-emitting window 1 of functional unit B.
So far, the annexation between the light mouth of functional unit A, functional unit B, functional unit C and functional unit D is determined to finish.
Second Application Example is used for determining the connection relation between optical interfaces of optical network node.Suppose that the part in the optical-fiber network or in the optical-fiber network exists optical network node A, optical network node B, optical network node C and optical network node D, each optical network node comprises light inlet 1, light inlet 2, light inlet 3, light-emitting window 1, light-emitting window 2 and light-emitting window 3, certainly, the light inlet quantity of each optical network node can be inequality with light-emitting window quantity, the light inlet quantity of each optical network node or light-emitting window quantity also can be inequality, here for convenience, suppose that quantity is all identical.
After each light inlet detected and may have the light-emitting window of annexation with it, gathering each light inlet and its, may to have the corresponding relation of light-emitting window of annexation with it as follows:
Figure GDA0000066627390000101
Table 2
As shown in Table 2, the light inlet 3 of the light inlet of optical network node A, D and optical network node B does not detect any light-emitting window of any optical network node, this can illustrate that the light inlet 3 of the light inlet of optical network node A, D and optical network node B does not have to have annexation with any light-emitting window of any optical network node.
Other steps of determining the annexation between the light mouth of optical network node are identical with the described step of table 1.
Need to prove that flow process shown in Figure 1 is a kind of embodiment of first method of the present invention, in actual applications, first method of the present invention can also have a variety of embodiments.
For example, can press the ordering of the detected light-emitting window sign of light inlet quantity according to the label detection result; To label detection quantity all greater than 1 and quantity to differ be that two detected signs of light inlet of 1 compare, if two signs that light inlet detected have and only have one different, then have annexation between a fairly large number of light inlet of label detection and the pairing light-emitting window of described different sign; To label detection quantity is 1 light inlet, then determines to have annexation between described light inlet and the pairing light-emitting window of described sign.The essence of this mode is, find out two light inlets that ordering is adjacent at random, these two detected signs of light inlet have and only have one different, can determine to have annexation between a fairly large number of light inlet of label detection and the pairing light-emitting window of described different sign so.Can adopt this mode for all light inlets in sequence, till finding the light-emitting window that has annexation with it for all light inlets in the sequence.
Again for example, can press the ordering of the detected light-emitting window sign of light inlet quantity according to the label detection result; Find earlier and detect the maximum light inlet of light-emitting window sign quantity, for convenience of description, this light inlet is called light inlet A, find again and detect light-emitting window sign quantity and lack 1 light inlet than the detected light-emitting window sign of light inlet A quantity, here this light inlet is called light inlet B, wherein, light inlet A and light inlet B have detected and a different sign have only been arranged, and then can determine to have annexation between the corresponding light-emitting window of the different sign of light inlet A and this.Find again than the detected light-emitting window sign of light inlet B quantity and lack 1 light inlet, here this light inlet is called light inlet C, the same mode that compares light inlet A and light inlet B of using, come comparison light inlet B and light inlet C, by that analogy, can determine annexation between all light inlets and the light-emitting window.The essence of this mode is, according to detected light-emitting window sign quantity order from more to less, for each light inlet in the sequence finds the light-emitting window that has annexation with it.This mode is just in time opposite with mode shown in Figure 1.
First method of the present invention can be realized by the device of various ways, a kind of device wherein can comprise: the sign loading unit is used on each light-emitting window of optical wavelength signal or optical multiplexing section signal process described optical wavelength signal or optical multiplexing section signal loading sign; The label detection unit is used for that the sign to described optical wavelength signal or optical multiplexing section signal loading detects on each light inlet of described optical wavelength signal or optical multiplexing section signal process; The annexation determining unit is used for the result according to label detection, determines the annexation between light inlet and the light-emitting window.
In wdm system, it all is man-to-man basically that optical patchcord between the light mouth connects, power loss generally is lower than 0.2dB the process of light inlet of annexation to having with this light-emitting window and light signal is from light-emitting window, if optical wavelength signal or optical multiplexing section signal are without amplifier, then optical wavelength signal or optical multiplexing section signal power in the process of transmission should successively decrease, so, when passing through follow-up certain or some light inlet again through the optical wavelength signal of certain light-emitting window or optical multiplexing section signal, optical wavelength signal or the optical multiplexing section signal power during through this light-emitting window is the power greater than through these light inlets the time necessarily, and the power of the power of optical wavelength signal or the optical multiplexing section signal power during through the light inlet that has annexation with this light-emitting window with respect to through other follow-up light inlets time the when necessarily more approaching through this light-emitting window.Therefore, utilize the characteristics of optical wavelength signal or the power attenuation in transmission course of optical multiplexing section signal, also can determine the annexation between the light mouth.
For the foregoing reasons, the present invention also provides definite method of second kind of connection relation between optical interfaces.Second method can be applied in the optical regenerator section, optical regenerator section can refer to optical wavelength signal or optical multiplexing section signal in regeneration or after amplifying and before regeneration next time or amplification the distance of process, wherein, the optical regenerator section source can be devices such as amplifier.The overall technical architecture of second method is: in optical wavelength signal or the optical multiplexing section signal loading sign of optical signal source to being sent, or on the optical regenerator section source to the optical wavelength signal that amplified or optical multiplexing section signal loading sign, and in the optical regenerator section of described optical wavelength signal or the follow-up process of optical multiplexing section signal, detect sign on each light inlet and the light-emitting window; According to the relation of the marking matched and power match between light inlet and the light-emitting window, determine the annexation between described light-emitting window and the described light inlet.
Wherein, determine annexation between described light inlet and the described light-emitting window: according to the power of the detected optical wavelength signal of described light inlet, the power of optical multiplexing section signal or the power of sign, to described light inlet ordering according to following steps; According to the power of detected optical wavelength signal on the described light-emitting window, the power of optical multiplexing section signal or the power of sign, described light-emitting window is increased in the described light inlet sequence; If have and only have a light-emitting window between described two adjacent light inlets, then determine to detect in described light-emitting window and described two light inlets between the light inlet of lower-wattage and have annexation; If described light inlet had and only have a light-emitting window before described light inlet, then determine to have annexation between described light-emitting window and the described light inlet.
In addition, can also determine annexation between described light inlet and the described light-emitting window: according to the power of the detected optical wavelength signal of described light-emitting window, the power of optical multiplexing section signal or the power of sign, to described light-emitting window ordering according to following steps; According to the power of detected optical wavelength signal on the described light inlet, the power of optical multiplexing section signal or the power of sign, described light inlet is increased in the described light-emitting window sequence; If have and only have a light inlet between described two adjacent light-emitting windows, then determine to detect in described light inlet and described two light-emitting windows between the light-emitting window of higher-wattage and have annexation; If described light-emitting window has and only have a light inlet after described light-emitting window, then determine to have annexation between described light-emitting window and the described light inlet.
Further, if the power of the power of the power of detected optical wavelength signal, optical multiplexing section signal or sign is higher than the power of detected optical wavelength signal on any one light-emitting window, the power of optical multiplexing section signal or the power of sign on a light inlet, has annexation between the pairing light-emitting window of sign that then definite described light inlet and optical signal source or optical regenerator section source load.
Further, if the power difference of the power of the power of the power of the power of detected optical wavelength signal, optical multiplexing section signal or sign and power, the optical multiplexing section signal of detected optical wavelength signal on any one light inlet or sign determines then that all greater than the power difference thresholding that sets in advance the optical fiber connection relation relevant with described light-emitting window is unusual on a light-emitting window.
Below in conjunction with Fig. 2, second method of the present invention is elaborated.As shown in Figure 2, comprise the steps:
Step S201:, perhaps on the optical regenerator section source, the optical wavelength signal or the optical multiplexing section signal loading of being amplified identified in the optical wavelength signal or the optical multiplexing section signal loading sign of optical signal source to sending.
In the second approach, have only optical signal source or optical regenerator section source just in optical wavelength signal that sends or amplify or optical multiplexing section signal, to load sign, and other light-emitting windows are the same with light inlet, only detect sign, and do not load sign.Optical signal source can be an optical network node, also can be an optical network device functional unit, for example wavelength conversion unit etc.
Step S202: in the optical regenerator section of described optical wavelength signal or optical multiplexing section signal process, detect sign on each light inlet and the light-emitting window.
Step S203: will detect the light inlet of sign of equal number and content and the corresponding relation between light-emitting window and its detected information respectively and be aggregated into a group.
For a light inlet or light-emitting window, if also pass through other certain or some light inlet or light-emitting windows through the optical wavelength signal of this light inlet or light-emitting window or optical multiplexing section signal, then the quantity of this light inlet or the detected sign of light-emitting window and content can be with other the quantity and the content of certain or some detected signs of light inlet identical; If through the optical wavelength signal of this light inlet or light-emitting window or optical multiplexing section signal without other certain or some light inlet or light-emitting window, perhaps, if through the optical wavelength signal of other certain or some light inlets or light-emitting window or optical multiplexing section signal without this light inlet or light-emitting window, then the quantity of this light inlet or the detected sign of light-emitting window and content can be with other the quantity and the content of certain or some detected signs of light inlet different.
In step S203, can gather detecting light inlet and its detected all signs of sign of equal number and content and the corresponding relation between the corresponding luminous power information, accordingly, the corresponding relation with between the light-emitting window of line signal and its detected all signs and the corresponding luminous power information that detects equal number and content is gathered, can obtain a plurality of light inlet groups and light-emitting window group like this, and the quantity and the content of the quantity of the detected sign of light mouth in each group and content and the detected sign of other light mouths on the same group are identical.
Step S204: the light mouth to same group carries out power match, has annexation between light-emitting window that power mates most and the light inlet.
Concrete, for light-emitting window or the light inlet in each group, in the light inlet group or light-emitting window group of the sign that detects equal number and content with it, search light inlet or light-emitting window that the luminous power corresponding with its detected sign mated most, light inlet that finds or light-emitting window are light inlet or the light-emitting window that has annexation with it.
If with the light-emitting window is the light inlet that benchmark determines to have with it annexation, then can earlier the light-emitting window in the light-emitting window group be sorted, for example sort according to the descending order of power, equally, light inlet in the light inlet group of correspondence can also be sorted, corresponding light inlet group be meant with this light-emitting window group in light-emitting window detect the group that all light inlets of the sign of equal number and content are formed.After ordering is finished, be the light inlet that benchmark is determined and first light-emitting window has annexation with first light-emitting window in the light-emitting window group earlier, that is, from the light inlet group of correspondence, search detected corresponding luminous power less than and approach the light inlet of the detected corresponding luminous power of first light-emitting window most.In general, optical wavelength signal or the optical multiplexing section signal power during through certain light-emitting window with through and this light-emitting window have annexation light inlet the time power difference should be less than 0.2dB, but consider factor affecting such as accuracy of detection, can think that luminous power difference can be less than 1dB, so, the light inlet that finds should be that detected luminous power should be less than the light inlet of 1dB less than detected luminous power of light-emitting window and difference, and the light inlet that finds is the light inlet that has annexation with first light-emitting window.In like manner, be the light inlet that benchmark is determined and these light-emitting windows have annexation with other light-emitting windows again, after first light-emitting window group is determined to finish, again with the light-emitting window in other light-emitting window groups be benchmark determine with these light-emitting window groups in the light inlet of light-emitting window with annexation, so just can determine the annexation between the light mouth.
In like manner, if with the light inlet is the light-emitting window that benchmark determines to have with it annexation, then can earlier the light inlet in the light inlet group be sorted, for example sort according to the ascending order of power, equally, light-emitting window in the light-emitting window group of correspondence can also be sorted, corresponding light-emitting window group be meant with this light inlet group in light inlet detect the group that all light-emitting windows of the sign of equal number and content are formed.After ordering is finished, be the light-emitting window that benchmark is determined and first light inlet has annexation with first light inlet in the light inlet group earlier, promptly, from the light-emitting window group of correspondence, search detected corresponding luminous power greater than and approach the light-emitting window of the detected corresponding luminous power of first light inlet most.In general, optical wavelength signal or the optical multiplexing section signal power during through certain light inlet with through and this light inlet have annexation light-emitting window the time power difference should be less than 0.2dB, but consider factor affecting such as accuracy of detection, can think that luminous power difference can be less than 1dB, so, the light-emitting window that finds should be that detected luminous power should be less than the light-emitting window of 1dB greater than detected luminous power of this light inlet and difference, and the light-emitting window that finds is the light-emitting window that has annexation with first light inlet.In like manner, be the light-emitting window that benchmark is determined and these light inlets have annexation with other light inlets again, after first light inlet group is determined to finish, again with the light inlet in other light inlet groups be benchmark determine with these light inlet groups in the light-emitting window of light inlet with annexation, so also can determine the annexation between the light mouth.
Need to prove, if it is excessive to be in the luminous power difference of the light inlet of same position and light-emitting window correspondence in sequence, though can further infer between light-emitting window and the light inlet to have optical fiber connection relation, the optical fiber connection may be subjected to reasons such as optical patchcord end-face pollution, damage, bad connection to cause junction loss excessive.Do not match if detect the light-emitting window and the light inlet quantity of like-identified, can infer it is which light-emitting window back optical fiber connects unusually yet.

The light inlet and the light-emitting window that detect the sign of equal number and content are aggregated into a group respectively, and the result who gathers is as follows:
The light inlet group that detects S1, S3 is for { the light-emitting window group is { light-emitting window 2 of functional unit A, the light inlet 1} of functional unit B for the light inlet 1 of functional unit B, the light inlet 3} of functional unit C;
The light inlet group that detects S2, S4 is for { the light-emitting window group is { light-emitting window 3 of functional unit A, the light inlet 2} of functional unit B for the light inlet 2 of functional unit B, the light inlet 1} of functional unit C;
The light inlet group that detects S5, S6 is for { the light-emitting window group is { light-emitting window 1 of functional unit A, the light inlet 3} of functional unit B for the light inlet 3 of functional unit B, the light inlet 2} of functional unit C.
If the light-emitting window that light inlet 1 definite and functional unit B has annexation, then from detecting S1, it is more approaching to find out corresponding luminous power in the light-emitting window group of S3, and the light-emitting window that luminous power is bigger than the light inlet 1 of functional unit B, if the light-emitting window of functional unit A 2 detected corresponding luminous powers are respectively greater than the light inlet 1 detected corresponding luminous power of functional unit B, and detected luminous power approaches the light inlet 1 detected corresponding luminous power of functional unit B most in all detect greater than the light-emitting window of the corresponding luminous power of the light inlet 1 of functional unit B, and the light-emitting window 2 that then can determine functional unit A has annexation with the light inlet 1 of functional unit B.Definite method of other light mouth annexations by that analogy.Like this, all light inlets of functional unit A, B and C and the annexation between the light-emitting window can be determined.
In second method of the present invention, can have only optical signal source or optical regenerator section source to optical wavelength signal or optical multiplexing section signal loading sign, need not each light-emitting window all identifies the optical wavelength signal or the optical multiplexing section signal loading of process, the loss of having avoided the sign charger to introduce has been saved and has been introduced the cost that charger needs.
