Description

technical field [0001] The present application relates to optical communication technology, in particular, to an optical transceiver module with integrated optical fiber detection function and passive optical network (Passive Optical Network, PON) system and equipment, and the present application also relates to a method and system for optical fiber detection . Background technique [0002] With the continuous increase of users' demand for bandwidth, the traditional copper broadband access system is increasingly facing bandwidth bottlenecks; at the same time, the optical fiber communication technology with huge bandwidth capacity is becoming more and more mature, and the application cost is decreasing year by year. The optical fiber access network has become the next A strong competitor of the first-generation broadband access network, especially the passive optical network is more competitive. [0003] Generally speaking, a passive optical network system includes an optica...

Problems solved by technology

[0006] However, in the passive optical network system, the optical distribution network usually uses a passive optical splitter for signal branching / coupling. Due to the large power loss of the optical splitter, it is difficult for the optical transceiver module using the above-mentioned shared optical emission components Direct fault identification and demarcation of branch fibers

Therefore, when using the above-mentioned solution for optical fiber detection, it is still necessary to combine other means, such as adding optical reflectors to branch optical fibers for fault location, etc., which will not only increase the cost, but also increase the difficulty of construction
