Description
Technical Field
The invention relates to the technical field of maintenance of optical communication systems, in particular to a multi-disc multi-interface parallel fiber checking method and a multi-disc multi-interface parallel fiber checking device.
Background
In the process of laying and using a large number of FTTX (fiber to the home, FTTH, FTTB, and the like) optical fiber lines in the past, the lack of scientific and unified line marking and management standards causes the management confusion of the optical fiber lines in the existing optical access network, and the connection relationship of the optical fibers among optical distribution frames of a machine room, optical distribution frames and optical cross-connecting boxes is unclear. It is very difficult to find out the fault line accurately in a large number of mixed optical fibers, and the workload is large. The maintenance time of the optical communication network is precious, and long-time maintenance can cause the local paralysis of the communication network, thereby bringing great inconvenience and huge economic loss for work and life. Meanwhile, in actual life, based on the optimization of city planning, the situations of modifying or replacing the optical fiber line on the current layout are inevitable. Under the influence of many special circumstances, this can result in the non-functioning optical fibres not being removed in time, they still being connected to the optical equipment, forming a large number of dead fibres. These problems bring great inconvenience to the line management, troubleshooting, etc. in the passive optical network, resulting in low efficiency of the management system. The method for checking the optical fiber connection relationship among the machine room distribution frames and between the distribution frames and the optical cross-connecting box is an important ring for optical fiber circuit redeployment, and has important significance for optimizing the optical fiber circuit layout, improving the management efficiency and reducing the operation and maintenance cost of the existing optical network.
At present, researches based on optical fiber connection relations are not many, and mature efficient fiber searching schemes are rare. In order to clear the connection relationship of the optical fibers, the conventional investigation uses a red light pen or directly pulls the optical fibers to confirm the optical fibers one by one. In the face of a large number of disordered optical fiber connections between optical distribution frames, the mode is labor-consuming, and the time cost is greatly increased. The "LFD-300B FiberFinder" manufactured by EXFO, canada is a specialized device designed for fiber optic positioning and consists of two devices, a sending and a receiving device. The staff presss from both sides the transmitting device on waiting to look for the fiber circuit and sends the modulation light signal, and other end staff uses receiving equipment to press from both sides tightly one by one in a large amount of optic fibre of fiber distribution frame and looks for the modulation light signal, and receiving equipment received signal can confirm the fiber circuit route. The scheme is similar to the traditional checking mode, and the checking needs to be carried out in a large number of disordered optical fibers one by one, so that the efficiency is low. An instrument with a spectral analysis function is built in or out of an Optical signal processing single board of Huashi technology limited company, and is used for detecting single-wavelength Optical power to realize detection of an Optical fiber connection relation. On the basis of the existing optical network facilities, the schemes introduce auxiliary equipment such as an optical spectrum analyzer or the like or modify an optical distribution network, so that the economic and time cost of fiber checking is greatly increased.
Therefore, the efficient and convenient parallel fiber checking system and the fiber checking method are designed, the fiber checking cost and the fiber checking time are reduced, the network upgrading, maintenance and management cost in the later period is reduced, and the parallel fiber checking system and the parallel fiber checking method have great practical significance in the operation of the optical access network.

It should be noted that the number of plugging and unplugging the B-side is inversely proportional to the number of fibers to be checked at one time, and the fiber checking time can be significantly reduced by using a multi-disc multi-interface parallel fiber checking method (the fiber checking time is mainly determined by the number of times of plugging and unplugging the optical fibers manually).
Example 2
Referring to fig. 3-4, a multi-disk multi-interface parallel fiber checking method is provided as an embodiment of the present invention, and in order to verify the beneficial effects of the present invention, scientific demonstration is performed through simulation experiments.
In this embodiment, the following two application scenarios are implemented to clear the optical fiber connection relationship on the two optical distribution frames ODF (ODF a and ODF B): (1) The two ODF ports are application scenes of any permutation relation; (2) Two ODF ports are connected according to a certain known rule, but there are application scenarios where p% of the ports are not connected according to the rule.
For any permutation relationship of application scenarios 1, ODF a and ODF B both contain 288 fiber ports, i.e. each optical distribution frame contains 24 fiber trays, each fiber tray containing 12 fiber ports. Now, optical fiber connectors between the ports of ODF a and ODF B are cleaned by using fiber inspectors with n =1, 6, 12, 24, 48, 96 and 144 ports, respectively, where 6, 12, 24, 48, 96 and 144 optical fiber ports correspond to 0.5, 1, 2, 4, 8 and 12 optical fiber disks, respectively. According to the fiber checking method of the present invention, the number of times of plugging and unplugging required by the ODF a end is 288, the plugging and unplugging time is 0.8 hour (assuming that the plugging and unplugging time of each port is 10 seconds, the same applies below), the maximum number of times of plugging and unplugging required by the ODF B end is shown in fig. 3 (a), and the maximum plugging and unplugging time is shown in fig. 3 (B). As can be seen from fig. 3, as the number of ports of the fiber checking device increases, the number of times of plugging and unplugging and the plugging time are significantly reduced, and considering that the fiber checking time of the access network generally should not exceed 6 hours, when performing fiber checking between ODFs in the exchange relationship, the fiber checking device with 24 or more ports should be selected, because the fiber checking time of the fiber checking device with 24, 48, 96 and 144 ports is respectively 5.2, 2.8, 1.6 and 1.2 hours, which is lower than the required 6 hours.
Connecting optical fiber ports according to a certain rule, wherein the port connection relation of an application scene 2,XX (1-p%) with p% not connected according to the rule can be measured at one time according to the rule, wherein the frame A is plugged and pulled for N times, and the frame B is plugged and pulled for N times; the connection relations of the rest Nxp% optical fiber ports are checked according to the parallel fiber checking method adopted by the invention. Now, the conditions of p% =20%, 40%, 60%, 80% and 100% are examined by using fiber inspectors with n =1, 6, 12, 24, 48, 96 and 144 ports, respectively, and the maximum plugging times and plugging times obtained by simulation calculation are shown in fig. 4 (a) and (b), respectively. As can be seen from fig. 4, for all p values, as the number of ports of the fiber inspection device increases, the required plugging times and plugging time both decrease, and when the number of ports reaches 48, the plugging times and the plugging time tend to be horizontal, that is, the fiber connection relationship between the ports can be cleared within 6 hours by using 4 fiber inspection devices with 48 ports.
To sum up, the embodiment of the invention adopts a multi-disk multi-interface parallel fiber checking device and a fiber checking method to check the optical fiber connection relationship between the 288-port optical distribution frames in two application scenarios. The calculation result verifies the effectiveness of the multi-disk multi-interface parallel fiber checking device and the fiber checking method thereof in quickly checking the complex optical fiber connection relation between the ports of the optical distribution frame.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
