Fiber port line sequence tester of fiber access network

Abstract

The invention relates to a testing device of a fiber-optic communication system, in particular to a fiber port line sequence tester of a fiber access network. The fiber port line sequence tester is composed of a launcher and a receiver. The launcher comprises a plurality of lasers capable of inputting optical signals from the launching ends of a plurality of optical fibers to be tested respectively and a launching end central processing unit (CPU) capable of loading port information at the launching end of each optical fiber through the lasers. The receiver comprises a plurality of detectors capable of receiving port information transmitted from each optical fiber to be tested from the receiving end of each optical fiber to be tested. The signal output end of each detector is connected with a receiving end CPU, and the signal output portion of the receiving end CPU is connected with a receiving end data communication port capable of communicating with an external network management system and uploading data. By means of the fiber port line sequence tester of the fiber access network, a fiber port line sequence of the fiber access network can be tested, optical power detection can be conducted simultaneously, testing efficiency is high, and a detection result is precise.

Description

technical field [0001] The invention relates to a test device for an optical fiber communication system, in particular to a line sequence tester for an optical fiber port of an optical fiber access network. Background technique [0002] With the large-scale development of FTTX construction, there are more and more node devices in the optical fiber access line. From ODF to optical switch and optical fiber distribution box at the user end, there are a large number of optical fiber access ports, and the fiber routing information is becoming more and more huge. , It is difficult to maintain and manage, especially the office connection route between the upper and lower node devices. The traditional operation method is: the port correspondence between the upper and lower node devices uses a red light source to send red light from one port in turn, and the operation and maintenance personnel observe and record the port correspondence at the other end. The insertion loss of the fib...
