Description
Technical field
The present invention relates to PON (Passive Optical Network, passive optical network) resource alignment technique fields, especially
It is related to a kind of acquisition methods and device of PON network resource data.
Background technology
Swift and violent growth and the development of optical communication technique and the reduction of cost with access net to service bandwidth demand, light
Fiber communication with it, long lifespan transparent to business, bandwidth bearing capacity is virtually limitless, adapts to ever-increasing bandwidth and new business
The characteristics of growth requirement, becomes the important way of access layer network construction, and " light entering and copper back ", optical node gradually moves down, and optical fiber arrives
Guard station (FTTP：Fiber To The Premise), Fiber To The Building (FTTB：Fiber To The Building), optical fiber arrives
Office (FTTO：Fiber To The Office) and optical fiber until arrive family (FTTH：Fiber To The Home), at
For the inexorable trend of access layer network development.
PON technologies are a kind of point-to-multipoint transmission technologys, and the data terminal equipment being connected on trunk is known as optical link
Terminal (OLT：Optical Line Terminal), the data terminal equipment being connected on branch is known as optical network unit (ONU：
Optical Network Unit).OLT is typically disposed in service provider side, and ONU is generally placed upon user side.OLT and
It is connected by ODN (Optical Distribution Network, optical distribution network) between ONU, generally according to user
Apart from computer room distance, user distribution situation, ODN is using 1 grade or 2 grades light splitting.
The characteristics of due to PON network, any one port that an ONU is connected on optical splitter can work.For example, one
Optical splitter has 8 ports, is 1,2,3 respectively ... 8, this optical splitter has met 8 ONU respectively, is A respectively, B ... H users, this
A little users are exchanged port or are possible using a not used port.Which port of the corresponding optical splitter of user is usual
It is recorded in money guard system.
In early stage, lot of domestic and international operator is very extensive to the management of ODN, and there is no perfect money guard systems to manage
ODN and user.Although there are perfect money guard system in some operators, but data are imperfect, do not record user and optical splitter it
Between connection relation；Even if the data having are very complete when just beginning setting up, but as the network operation time is elongated, network
Service engineer is replacing optical fiber to user or is replacing port, does not synchronize and modifies inside money guard system, or replaces light
Not making label after fibre marks this user to be used by whom, or the label aging on optical fiber falls off or user's cancellation after a long time
Corresponding fiber port is not removed afterwards, the above variety of problems, is eventually led to operator and is not aware that a user uses point
Which the port of light device is, inside money guard system, has a large amount of idle ports inside optical splitter, but no one knows which is empty
Spare time can not be used for open-minded to new user；When ODN breaks down, do not know that this is repaired from which port yet.

Fifth embodiment of the invention, the present embodiment are on the basis of the above embodiments, one to be introduced in conjunction with attached drawing 5~9
The application example of the present invention.
As shown in figure 5, the acquisition system of the PON network resource data of the present invention includes：The acquisition of PON network resource data
Device and mobile phone.
The embodiment of the present invention application scene be：Money guard system on store accurate PON mouthfuls to a secondary light-splitting device it
Between connection relation, also store ONU under which PON mouthfuls and the corresponding user informations of these ONU, but there is no final stage
Connection relation between optical splitter and ONU, or have connection relation, but connection relation might not be correct.
Check and correction server has interface with money guard system, PON EMS (i.e. PON webmasters), cell phone application, completes the receipts of data
Collection and correction.
Cell phone application is to proofread the tool of engineer, completes scanning final stage optical splitter serial number, starts check and correction.
PON webmasters：The webmaster of OLT network elements
Macrobend presss from both sides：Decaying is manufactured by pressing from both sides a bending less than fiber bending radius on optical fiber.
Macrobend accompanies a variety of embodiments, and the most common type structure has been drawn in Fig. 7~9 of the embodiment of the present invention.
As shown in fig. 6, the acquisition flow of the PON network resource data of the embodiment of the present invention is as follows：
Step S1, engineer reach final stage optical splitter position, are scanned using cell phone application or input optical splitter ID, and input waits for
The optical splitter port numbers of check and correction.
Step S2 starts the check and correction in cell phone application.
Optical splitter ID, optical splitter port numbers to be proofreaded are sent to check and correction server by step S3, cell phone application.
Step S4, it is PON mouthfuls corresponding that check and correction server to money guard system inquires this optical splitter.
Step S5, money pipe server return to PON messages breath.
Step S6, OLS information of the check and correction server to current this PON mouthfuls lower whole ONU information of PON EMS inquiries.
Explanation：OLS data are photosphere link monitorings, include the following parameter of the optical module of ONU：Received optical power, temperature,
Electric current and voltage, the embodiment of the present invention only use the received optical power of the optical module of ONU.
Step S7, check and correction server notify cell phone application：OLS information before macrobend, which has obtained, to be finished.
Step S8, cell phone application notify engineer：It please manufacture macrobend.
Step S9, engineer manufacture tool using macrobend：Macrobend presss from both sides, this root fibre clip on this port of optical splitter
Go out a macrobend, macrobending loss about 1dB, and the lowest power needed for the business of user operation is 2~3dB.
Step S10, engineer click cell phone application interface：Macrobend completes.Cell phone application notice check and correction server：Macrobend
It completes.
Step S11, OLS information of the check and correction server to current this PON mouthfuls lower whole ONU of PON EMS inquiries.
Step S12 compares the OLS information of this 2 groups of ONU of step S6 and step S11：
If a) not finding light or finding there is that ONU is offline, this offline ONU is just attached to this optical splitter
The ONU of port.
B) if it find that there is received optical power obviously to weaken, it is more than threshold value, illustrates that this ONU is just attached to this light splitting
The ONU of device port.
Step S13, check and correction server identifies ONU, optical splitter mark, optical splitter port numbers are sent to money piping blanket insurance
It deposits.If carrying label machine, label can be pasted onto on the optical fiber of this port by engineer with print label.
Step S14, engineer unclamp macrobend folder, carry out the check and correction of next optical splitter port.
It is repeated in the above action, completes the check and correction of each optical splitter upper port.
By the explanation of specific implementation mode, should can to the present invention for reach technological means that predetermined purpose is taken and
Effect is able to more go deep into and specifically understand, however appended diagram is only to provide reference and description and is used, and is not used for originally
Invention limits.

The received optical power or OLT of the ONU becomes insignificant values for the received optical power of the ONU from virtual value.
10. the acquisition device of PON network resource data according to claim 6, which is characterized in that described device is also wrapped
It includes：
Be bent control module, for using macrobend folder the optical fiber of the port is bent and to the optical fiber of the port into
The bending radius of row bending is less than the extreme flexion radius of the optical fiber；
After being bent to the optical fiber of the port, the received optical power or OLT of the ONU are directed to the reception light of the ONU
The decaying of power is less than lowest power needed for business.
