Monitoring system and monitoring method for transmitting power of SR4 optical module

Abstract

The invention relates to the field of optical transceiver, and in particular relates to a monitoring system and a monitoring method for transmitting power of an SR4 optical module. The monitoring system comprises a transmitting device and a monitoring device, wherein the transmitting device transmits input light beams, and the monitoring device receives the reflected light beams; the monitoring system also comprises a reflection device, a main control device and an inclined optical fiber end face, wherein the transmission device sends the input light beams to the reflection device, the reflection device reflects the input light beams to the optical fiber end face, the optical fiber end face reflect a part of reflected light beams to the reflection device, the reflection device reflects thereflected light beams to the monitoring device, the monitoring device detects a power parameter of the reflected light beams and sends the power parameter of the reflected light beams to the main control device, and the main control device controls the transmitting power of the transmitting device according to the power parameter of the reflected light beams. According to the system and the method provided by the invention, direct monitoring on the transmitting power of the SR4 optical module is achieved by detecting the reflected light beams and controlling the transmitting power of the transmitting device, and monitoring accuracy of the transmitting power is prevented from being influenced by aging or temperature variation of the SR4 optical module.

Description

technical field [0001] The invention relates to the field of optical transceivers, in particular to a monitoring system and method for transmitting power of an SR4 optical module. Background technique [0002] At present, unlike people who pay attention to spectral efficiency and distance-bit rate product in long-distance networks, in the internal network of high-throughput data centers, the optical fiber used to connect servers is only a few meters to a few kilometers, and people pay more attention to The intra-site interconnection is realized by means of high-speed short-distance optical modules. [0003] The existing SR4 optical module (4-channel parallel-optical-module for short reachoptical links, 4-channel short-distance optical module), usually adopts the solution of integrating four transceiver chips on the PCB board, and the single-channel rate is 25Gbps, that is, Can achieve up to 100Gbps aggregate rate. In this type of device, the transmitting power of the trans...
