A remote trigger fiber-to-fiber device

Abstract

The invention provides a remote trigger type optical fiber alignment device, which comprises a remote trigger type optical fiber alignment instrument and a hand-held terminal used together. The remote trigger type fiber alignment instrument includes a laser, a laser drive unit, a first main control unit and a first wireless communication unit; the signal connection between the first main control unit and the first wireless communication unit; the first main control unit passes through the laser The drive unit controls the opening and closing of the laser; the signal output end of the laser is connected to a group of optical fiber connectors through an optical switch; each optical fiber connector is equipped with a connector number for distinguishing other optical fiber connectors one-to-one. The handheld terminal includes a second main control unit, a second input unit and a second wireless communication unit, the second wireless communication unit is used in conjunction with the first wireless communication unit, and the second input unit is used in conjunction with each of the optical fiber connectors . The invention is used for improving the efficiency of fiber sequence testing work and improving the reliability of fiber sequence testing results.

Description

technical field [0001] The invention relates to the field of operation and maintenance of power communication optical cables in urban distribution networks, in particular to a remote trigger type optical fiber-to-fiber equipment. Background technique [0002] With the continuous development of the urban distribution network, the investment in maintaining the huge distribution network is getting higher and higher, and the environment in the communication lines of the distribution network is complex, and there are various uncertain factors, which make it difficult to measure the fiber sequence of the communication fiber optic cable, and the power supply Communication operation and maintenance personnel caused a lot of inconvenience in construction and maintenance. [0003] The traditional fiber sequence matching method requires at least two people to complete it. Among them, one person is required to send optical signals to the cores of the tested optical cable according to th...

AI Technical Summary

Problems solved by technology

[0004] (1) At least two people are required to cooperate to complete the work. When the staff is insufficient, it is basically impossible to carry out the fiber core test work, which may easily cause a delay in the construction period

[0005] (2) It is necessary to test the real-time voice communication between the two parties through the communication tool in the whole test process. Because the communication between the two parties remains unchanged, the communication takes a long time, which leads to the low efficiency of the optical fiber sequence test.

[0006] (3) The two sides of the test use communication tools to communicate, and there are situations where there are errors in the communication between the two parties, which leads to errors in the test results of the fiber sequence of the optical cable, and poses a safety hazard to the operation and use of the optical cable
