Abstract

The present application relates to an optical module monitoring system and method. The system comprises an I2C master and a programmable logic device, the programmable logic device includes a first I2C interface and a plurality of second I2C interfaces, the I2C master is based on the first I2C interface and is connected with the programmable logic device through a group of two-wire serial I2C buses, and a second I2C interface is connected with an optical module through a group of I2C buses. The I2C master is used for gating the target I2C interface corresponding to the first I2C interface andthe target optical module through the programmable logic device, a target address is written into the memory of the target optical module through the first I2C interface and the target I2C interface,and the status parameters stored in the target address returned by the target optical module are received. The system can realize the efficient monitoring of multiple optical modules through the simple communication logic scalability, and has the very high practicability.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a system and method for monitoring an optical module. Background technique [0002] With the development of digital technology and optical fiber communication technology, digital optical modules are widely used in communication systems. Therefore, the monitoring requirements of the operating status of optical modules are put on the agenda, so as to facilitate on-site and remote analysis of optical communication faults and communication quality. With the release of the SFF Committee (Small Form Factor Committee) SFF-8472 protocol, many optical module manufacturers have launched optical modules that support this protocol, providing a technical basis for real-time monitoring of optical modules. [0003] SFF-8472 stipulates that all optical modules supporting this protocol use the I2C bus interface to communicate. In I2C interface communication, it is stipulated...
