Abstract

The invention is applicable for the luminous power monitoring field, and provides a multi-mode luminous power monitoring method and a multi-mode luminous power monitoring device. A monitoring module comprises optical module anode and cathode interfaces, an anode image current source interface and a cathode image current source interface. The method comprises the following steps of determining the pin mode of a to-be-monitored optical device; according to the pin mode of the optical device, selecting one mode from three modes, namely the anode and cathode connection manner of the optical device, the anode image current source connection manner or the cathode image current source connection manner; connecting the anode and cathode of the optical device to the cathode and anode interfaces of the optical device when selecting the anode and cathode connection manner of the optical device, and providing a power supply to the anode interface of the optical module. The purpose that one device is applicable for the luminous power monitoring of the optical device with three pin modes is realized, and the development efficiency is improved.

Description

technical field [0001] The invention belongs to the field of optical power monitoring, in particular to a multi-mode optical power monitoring method and device. Background technique [0002] Now, the optical communication business is developing rapidly, and the role of the optical module is becoming more and more important. The core of the optical module is the optical device. Now there are more and more manufacturers that can produce optical devices, but the pin definition of the optical device is not clear. All are the same, so when designing an optical module, you can often use an optical device from a certain company, but it is not compatible with other versions. When another optical device has a price advantage, you have to redesign a new PCB to The application of the device is satisfied, thereby causing great waste. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a multi-modal optical power monitoring circuit ...
