Description

technical field [0001] The invention belongs to optical communication test technology, in particular to an optical communication comprehensive tester. Background technique [0002] Digital optical communication system is the most basic and important part of communication network. Testing is required in the opening, daily maintenance and troubleshooting of communication networks, as well as in the development, production and installation of communication equipment. At present, these tests require many different instruments to measure, such as light source, optical power meter, various bit error meters (2M / 8M bit error meter, data port bit error meter, NRZ / RZ bit error meter, A port bit error meter etc.), audio analyzers and channel characteristic analyzers, etc., there are many defects in the test, such as carrying too many instruments, unable to quickly find faults, poor mobility, and low test efficiency. [0003] At present, optical communication comprehensive testers are...

Problems solved by technology

[0004] Due to the traditional comprehensive integration technology, a variety of different test functions are independently designed, which will lead to excessive circuit scale and high power consumption, which cannot be powered by batteries and integrated into a small device

Therefore, the current optical communication comprehensive test instrument has weak test function and large volume, and does not have the ability to comprehensively test the optical communication system, that is, to simultaneously test the optical and electrical parameters of the communication interface, including system transmission index test, voice channel characteristic test and Fiber optic cable maintenance test and other functions
