Abstract

The invention discloses an optical module and an optical module LOS optimization method, and the optical module comprises an optical detector which is used for converting an optical signal into an electric signal. The limiting amplifier is provided with an LOS signal pin and is used for outputting a high level or a low level; the APD boost circuit comprises a control interface; the power supply interface is connected with the optical detector; and the output interface outputs a power signal of the optical signal. The MCU comprises a detection pin which is connected with the output interface and is used for receiving the power signal; the input pin is connected with the limiting amplifier and is used for receiving the high level or the low level; the adjusting pin is connected with the control interface, and a power signal monitoring value is set in the MCU; and when the operation judges that the power signal is smaller than the monitoring value, and the input pin receives a high level, the adjusting pin sends a signal to the control interface to supply the output voltage of the interface to rise, or the limiting adjusting pin sends a regulation signal to the limiting adjusting end to reduce the LOS threshold, and the LOS performance of the optical module is optimized.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an optical module and an optical module LOS optimization method. Background technique [0002] With the development of cloud computing, mobile Internet, video and other new business and application models, the development and progress of optical communication technology has become more and more important. In optical communication technology, the optical module is a tool to realize the mutual conversion of photoelectric signals, and is one of the key components in optical communication equipment. [0003] In the application, there is a type of optical module whose rate is not high, but requires a long transmission distance. Because of the long-distance transmission, the sensitivity, LOSD, LOSA and LOSH indicators of the optical receiving end are approaching the limit. When the received optical power is very small, the amplitude of the electrical signal gener...
