Embodiment two
The optical fiber connection relation checking method basic procedure of second embodiment of the invention can be with reference to figure 4, present embodiment is in conjunction with the optical fiber connection diagram of the network element device of present embodiment shown in Figure 3, situation with the annexation of finding to close glistening light of waves fibre is that example describes, mainly the comprising of this optical fiber connection relation checking method:
Step 201 is turn-offed the output port (that is: the output port of U21, U22, U23 and U24) that each interior light signal of network element device shown in Figure 3 is handled veneer, selects a light signal to handle veneer arbitrarily, for example: selective light signal processing veneer U21.
Step 202 is handled veneer with the light signal of secondary light source output from the light signal that the input port that light signal is handled veneer imports to described selection.
Step 203, the light signal of opening described selection is handled the output port of veneer, judges whether that other light signal processing veneer detects the signal of the light signal processing veneer output of described selection; If, then determine this light signal that detects signal handle veneer be the light signal of described selection handle veneer handle veneer in abutting connection with the downstream light signal.
Light signal selected in the step 202 being handled the output port of veneer U21 opens, because having only this moment light signal to handle veneer U21 receives light signal and has only the output port of light signal processing veneer U21 to open, so that should have only light signal processing veneer U21 just can receive light signal in abutting connection with downstream light signal veneer, with reference to Fig. 3, can determine this moment except that light signal is handled veneer U21, to have only light signal to handle veneer U22 and just can detect light signal, enter step 204.
Because each veneer generally can be to SCC (System control ﹠amp in the network equipment; Communication, system control with communicate by letter) veneer reports state (whether the signal input is arranged) separately, therefore, just the state judgement that can report according to each veneer is that each light signal processing veneer has not received light signal.In the present embodiment, just can handle the state that veneer U21, U22, U23, U24 report according to light signal, judge except light signal is handled veneer U21, have only light signal to handle veneer U22 and received light signal, just can determine light signal handle veneer U22 be light signal handle veneer U21 in abutting connection with downstream light signal processing veneer.
Step 204 is handled veneer at what step 203 was determined in abutting connection with the downstream light signal, and execution in step 203 promptly, is handled veneer U22, execution in step 203 at what light signal was handled veneer U21 in abutting connection with the downstream light signal.
Be specially: open the output port that light signal is handled veneer U22, judge and have only light signal to handle veneer U23 to detect the light signal that light signal is handled veneer U22 output, that light signal can be handled then that veneer U23 is defined as that light signal handles veneer U22 handles veneer in abutting connection with the downstream light signal.Handle veneer U23 at what light signal was handled veneer U22 in abutting connection with the downstream light signal then, execution in step 203, be specially: open the output port that light signal is handled veneer U23, judge and have only light signal to handle veneer U24 to detect the light signal that light signal is handled veneer U23 output, then can determine light signal handle veneer be U24 be light signal handle veneer U23 handle veneer in abutting connection with the downstream light signal.Handle veneer U24 at what light signal was handled veneer U23 in abutting connection with the downstream light signal then, execution in step 203 is specially: open the output port that light signal is handled veneer U24, judge to detect light signal without any veneer, then execution in step 205.
Step 205 judges whether that light signal is handled veneer without whether having in abutting connection with the judgement of downstream light signal processing veneer in addition; If no, then enter step 207; If have, then enter step 206, promptly, select one of them veneer execution in step 202 without whether having in the light signal light signal processing veneer of handling the veneer judgement in abutting connection with the downstream light signal.
Step 207 can be determined as shown in Figure 4 optical fiber connection relation according to above-mentioned steps.
In addition, if what select at the beginning in the present embodiment step 202 is exactly that light signal is handled veneer U24, and supposition is except light signal is handled veneer U24, light signal is handled veneer and is detected light signal never again, can determine that in step 203 light signal processing veneer U24 does not handle veneer in abutting connection with the downstream light signal, the non-downstream light signal processing veneer that then all light signals processing veneers (for example, U21, U22 and U23) except that light signal is handled veneer U24 in the equipment is referred to as light signal processing veneer U24 enters step 205.
In step 205, judge to also have U21, U22 and U23 not through whether the judgement of handling veneer in abutting connection with the downstream light signal being arranged, enter step 206.
Step 206 is handled a light signal processing of selection veneer execution in step 202 in the veneer at U21, U22 and these light signals of U23.
Concrete can for: for example can be that light signal is handled veneer U22, then the light signal of secondary light source output be imported to light signal and handle among the veneer U22; Light signal being handled the output port of veneer U22 opens, judge whether that light signal processing veneer detects the light signal that light signal is handled veneer U22 output, judge and have only light signal to handle veneer U23 to detect the signal that light signal is handled veneer U22 output, that then light signal is handled that veneer U23 is defined as that light signal handles veneer U22 handles veneer in abutting connection with the downstream light signal; And then open the output port that light signal is handled veneer U23, judge and have only light signal to handle the light signal that veneer U24 detects light signal processing veneer U23 output, that then light signal is handled that veneer U24 is defined as that light signal handles veneer U23 handles veneer in abutting connection with the downstream light signal, so far light signal is handled veneer U22, U23, U24 has experienced all whether the judgement of handling veneer in abutting connection with the downstream light signal is arranged, and determined light signal processing veneer U22, U23, annexation between the U24, but handling veneer U21, light signal also do not have experience whether the judgement of handling veneer in abutting connection with the downstream light signal is arranged, therefore, also need handle veneer U21 at light signal, execution in step 202,203,204, be specially: the light signal of secondary light source output is imported among the light signal processing veneer U21; Light signal is handled the output port of veneer U21, judge and have only light signal to handle the signal that veneer U22 detects light signal processing veneer U21 output, that then light signal is handled that veneer U22 is defined as that light signal handles veneer U21 handles veneer in abutting connection with the downstream light signal, because this moment, light signal was handled the judgement whether veneer U21, U22, U23 and U24 have all experienced has in abutting connection with downstream light signal processing veneer, execution in step 207.
Step 207, handle veneer according to each light signal whether the judged result of handling veneer in abutting connection with the downstream light signal is arranged, each light signal that obtains network element device inside is handled the actual fiber annexation of veneer.
At network element device shown in Figure 4, just can learn the actual annexation of light signal processing veneer U21, U22, U23, U24: the output that light signal is handled veneer U21 connects the input that light signal is handled veneer U22, the output that light signal is handled veneer U22 connects the input that light signal is handled veneer U23, and the output that light signal is handled veneer U23 connects the input that light signal is handled veneer U24.
In the present embodiment, each light signal of the network element internal that obtains can also be handled the actual fiber annexation of veneer, compare with the optical fiber connection relation of expection, whether the actual fiber annexation of handling veneer with each light signal of judging network element internal exists mistake, and the output error prompting.
Present embodiment imports optional light signal processing veneer by the light signal of control secondary light source output, the light signal of opening described selection is handled the output port of veneer, judge whether that other light signal processing veneer detects the signal of the light signal processing veneer output of described selection, thereby that judges described selection handles veneer in abutting connection with the downstream light signal, handle veneer at each light signal and carry out the discovery that above-mentioned steps can realize the upstream and downstream annexation between each light signal processing veneer, need not external OSA instrument or annexation is checked in built-in OSA unit, avoid introducing the risk that new optical fiber connects and introduce the fine mistake of new company, can not increase the cost of external OSA instrument or built-in OSA unit, simultaneously in the embodiment of the invention when the connection of each veneer that detects a network element device inside, do not need to rely on upstream network element and send light signal, just can realize the inspection of the interior veneer annexation of each network element device yet at the networking initial stage to this network element.
Embodiment three
For the ease of understanding, below optical fiber connection relation checking method provided by the invention is described in detail: present embodiment is that example describes with the annexation inspection of single glistening light of waves fibre.Referring to Fig. 1, U3 is a partial wave signal processing veneer, partial wave signal processing veneer U3 carries out demultiplexing with its wavelength-division multiplex signals that receives, and exports single wavelength signals from its each output port, and each output port of U3 connects a single wavelength light signal processing veneer respectively.Referring to Fig. 5, be the 3rd embodiment flow chart of optical fiber connection relation checking method provided by the invention, this method comprises:
Step 301 is turn-offed the output port that each interior light signal of a network element device is handled veneer.
Referring to Fig. 1, turn-off the output port of all veneers, all there is a switch output port and input port front that each light signal is handled veneer, and this switch can be controlled each light signal and handle the shutoff of veneer output port and input port with closed.Each light signal that turn-offs network element device is handled the output port of veneer, and light signal can't transmit in whole network element equipment.
Step 302 selects a light signal to handle veneer U3, and the light signal that secondary light source is exported imports described light signal processing veneer U3.Secondary light source is that the outside light signal of getting involved is handled the tunable optical source of veneer or is built in the interior tunable optical source of light signal processing veneer, can send the light signal of variable power or the light signal of wavelength change.
Step 303 is regulated the described secondary light source of input, makes that the wavelength of the light signal enter U3 (U3 is a partial wave signal processing veneer) is a kind of among the multi-wavelength who is scheduled to.For example, wavelength is the light signal of λ 1.
In this step, can regulate described secondary light source, make the light signal center wavelength that enters described partial wave signal processing veneer between the center for standard wavelength, switch.For example, the wavelength of the light signal that sends of control secondary light source is a certain standard wave length that G.694.1 ITU-T advises defined.The light signal of λ 1 wavelength of the light signal that tunable optical source sends can be set.
In this step, if what enter into partial wave signal processing veneer is the light signal that λ 1 wavelength is, judge whether that the light signal except that partial wave signal processing veneer handles the light signal that veneer is received this λ 1 wavelength, if determine that then λ 1 wavelength that this light signal processing veneer is a partial wave signal processing veneer is pairing in abutting connection with downstream light signal processing veneer.Be input to the wavelength of the light signal of partial wave signal processing veneer by adjustment, just can determine each wavelength of partial wave signal processing veneer pairing in abutting connection with the downstream single wavelength light signal processing veneer.
Need to prove, for a concrete partial wave signal processing veneer, its each output port is the light signal of output specific wavelength generally speaking, therefore, adjustment is input to the wavelength of the light signal of partial wave signal processing veneer, thereby just can determine the annexation of single wavelength light signal processing veneer of each output port of partial wave signal processing veneer and respective wavelength.
In the present embodiment, the wavelength that can regulate tunable optical source is other standard wave length that G.694.1 ITU-T advises defined, execution in step 304 then, promptly can finish partial wave and handle all single long wavelength fiber output ports of veneer are connected situation with the optical fiber of each downstream single wavelength light signal processing veneer discovery
In the present embodiment, can further include: with the actual annexation of output port with the long light signal processing of the veneer veneer of the partial wave signal processing veneer found, and the expection optical fiber connection relation in the described network element device between each light signal veneer compares, and connects whether there is mistake to find the optical fiber that each light signal is handled between the veneer in the described equipment.When having mistake, the output error prompting.
Because in practice, the wavelength range of receiving of some single wavelength light signal processing veneers is wide ranges, so even incorrect link has appearred in the output port of single wavelength light signal processing veneer and partial wave signal processing veneer, but should also might receive signal by list wavelength signals processing veneer.For example, what the output port 1 of partial wave signal processing veneer was exported is that wavelength is the light signal of λ 1, what output port 2 was exported is that wavelength is the light signal of λ 2, single wavelength light signal processing veneer 1 should be that the receiving center wavelength is the light signal of λ 1, and single wavelength light signal processing veneer 2 should be that the receiving center wavelength is the light signal of λ 2.In the optical fiber of reality connects, single wavelength light signal processing veneer 1 is connected to the output port 2 of partial wave signal processing veneer, single wavelength light signal processing veneer 2 is connected to the output port 1 of partial wave signal processing veneer, because single wavelength light signal processing veneer 1,2 wavelength range of receiving is a wide range, therefore, the wavelength that is input to the light signal of partial wave signal processing veneer when adjusting is λ 1, during λ 2, single wavelength light signal processing veneer 2,1 reports respectively and detects light signal separately, but in fact this optical fiber connection relation is incorrect, but is not found out.
The embodiment of the invention can further include: secondary light source is regulated, made the wavelength of the light signal that secondary light source is exported finely tune near the certain criteria centre wavelength of its output.For example, make the wavelength of the light signal that secondary light source is exported finely tune at standard wave length λ about 1.
" judging whether that other light signal processing veneer detects the light signal of described wavelength " in the step 304 is specifically as follows: judge whether that other light signal processing veneer detects the consistent light signal of wavelength change direction of the light signal of exporting with secondary light source.If have, then can determine this light signal to handle veneer be that partial wave signal processing veneer is corresponding under this specific criteria centre wavelength to handle veneer in abutting connection with the downstream light signal.
Present embodiment imports selected partial wave signal processing veneer by the light signal of control secondary light source output predetermined wavelength, open the output port of selected partial wave signal processing veneer, judge whether that other light signal processing veneer detects the light signal of this wavelength, handle veneer thereby this wavelength of judging partial wave signal processing veneer is pairing in abutting connection with the downstream light signal, thereby realize that each minute wave optical signal handles the discovery of the annexation of the delivery outlet of upstream and downstream annexation between veneer and single wavelength light signal processing veneer and partial wave processing veneer and single wavelength light signal processing veneer, need not external OSA instrument or annexation is checked in built-in OSA unit, avoid introducing the risk that new optical fiber connects and introduce the fine mistake of new company, can not increase the cost of external OSA instrument or built-in OSA unit, handle the centre wavelength of veneer by fine setting transmitting terminal list wave optical signal, detect the situation of veneer receiving optical signals, prevent that wide range from receiving the judgement that veneer influences optical fiber connection relation, further improve optical fiber and connected the accuracy of checking, simultaneously in the embodiment of the invention when the connection of each veneer that detects a network element device inside, do not need to rely on upstream network element and send light signal, just can realize the inspection of the interior veneer annexation of each network element device yet at the networking initial stage to this network element.

For the ease of understanding, with concrete application scenarios the foregoing description is described in detail below:
Referring to Fig. 7, Fig. 7 is the schematic diagram that should use scene 1, and it is correct connection that solid line connects, and dotted line is to use connection wrong in the scene,
Step 701, switch control module 51 turn-offs the output port of each light signal processing veneer (U1, U2, U3 and U4 veneer) in the network element device.
Step 702, light signal output module 52 selects a light signal to handle veneer U1, and control is given U1 from the light signal of the state variation of light source;
Step 703, optical signal detecting module 53 detect the light signal that other those light signals processing veneers U2 receives and the variation of light source light signal condition is consistent except that the light signal of selecting is handled veneer U1;
Step 704, the reception condition U2 that optical signal detecting module 53 is handled veneer according to each light signal receives the light signal U3 of variation and the light signal that U4 does not receive variation, the upstream and downstream annexation that obtains light signal processing veneer is: U3 and U4 are the non-downstream veneers of U1, and the downstream of U1 connects U2.
Wherein the relation of the upstream and downstream between U3 and the U4 does not detect, thereby second control module 55 control light signal output modules, optical signal detecting module and first control module are carried out the upstream and downstream annexation that step 702-704 obtains U3 and U4 again, annexation acquisition module 56 obtains all light signals according to above-mentioned situation about detecting and handles the accurate upstream and downstream annexation of veneer, error checking module 58 judges whether these annexations are consistent with the correct annexation that presets, the inconsistent connection error of then exporting.
Scene 2, same, can be referring to Fig. 8, Fig. 8 is the schematic diagram that should use scene, and solid line is the connection of user expectation, and dotted line is that factual error connects.
The optical fiber of user expectation is connected to: the delivery outlet 1 of single wavelength light signal processing veneer 1 (OTU1) and U3 is connected, and the delivery outlet 2 of OTU2 plate and U3 is connected, by that analogy.And actual optical fiber to connect be wrong, the OTU1 plate is connected with the delivery outlet 2 of U3, the delivery outlet 1 of OTU2 plate and U3 is connected, and utilizes the whether method of mistake of optical fiber connection relation checking method inspection connection in this case:
Step 801, light signal output module 52 are sent the light signal that wavelength is λ 1.
Step 802, optical signal detecting module 53 detects finds that receive λ 1 wavelength light signal is single wavelength light signal processing veneer OTU2.
Step 803, (λ 1 is from delivery outlet 1 output according to the characteristic of the wavelength and the U3 veneer itself of tunable optical signal for optical signal detecting module 53, λ 2 is from delivery outlet 2 outputs, the rest may be inferred), obtain the corresponding annexation of λ 1 wavelength light signal and U3 delivery outlet, OTU2 is the downstream veneer that the branch wave optical signal is handled veneer, and can know that OTU2 is connected with the delivery outlet that divides wave optical signal to handle the λ 1 of veneer U3; The delivery outlet 1 that can know OTU2 and U3 links to each other, error checking module 58 output optical fibre connection errors.
Can check the annexation that obtains OTU1 and U3 delivery outlet with above-mentioned same method, regulate the wavelength of the light signal of secondary light source output, travel through all single wavelength light signal processing veneers, repeat above-mentioned steps, can obtain all OTU plates and the annexation of closing glistening light of waves processing unit U3.Judging whether this connection is consistent with the connection of expection, is then to export to connect correctly, otherwise output connection error.

Step 901, light signal output module 52 control secondary light sources send the light signal that central wavelength lambda 1 is changed and handle veneer OTU1 for single wave optical signal.
Whether step 902, optical signal detecting module 53 detect has light signal to handle veneer to have received the consistent light signal of change in optical signal that wavelength change and secondary light source send.It is the downstream veneer of OTU1 that the light signal of determining to receive the consistent light signal of change in optical signal that wavelength change and secondary light source send is handled veneer U4.
In like manner, can find that U3 is the downstream veneer of OTU2 and OTU4 in reality connects, U4 is the downstream veneer of OTU1, OTU3.
Step 903, according to each the single wavelength light signal processing veneer determined and the annexation of downstream veneer, the annexation of contrast user expectation, under inconsistent situation, the prompting of output annexation mistake.
The present invention sends tunable optical signal to veneer by the adjustable secondary light source of control, reception condition according to each veneer, obtain the upstream and downstream annexation of each veneer, avoid introducing new optical fiber connection and cause the testing result mistake, can not increase the cost of external OSA instrument or built-in OSA unit.Guaranteeing to close under the correct situation of the fine connection of the glistening light of waves, can also detect single wave optical signal and handle the annexation of the delivery outlet of veneer and each partial wave processing veneer, handle the centre wavelength of veneer by fine setting transmitting terminal list wave optical signal, detect the situation of veneer receiving optical signals, prevent that wide range from receiving the judgement that veneer influences optical fiber connection relation.Further improve optical fiber and connected the accuracy of checking.
