Digital Diagnostic Monitoring (DDM) is a common feature in optical modules that provides real-time monitoring and diagnostic information about module performance and status.  DDM enables network administrators to better understand the operation of optical modules, enabling troubleshooting and performance optimization. The five real-time measurement parameters monitored by DDM are:  How does DDM work? DDM functionality is achieved by embedding a set of monitoring parameters and sensors in the optical module. These parameters include transmit power, receive power, operating temperature, voltage and other related indicators. The optical module communicates with external devices such as switches through internal digital chips, and transmits real-time…

The purpose of the battery charging performance test is to check the charging ability of the lithium-ion battery in different states. Battery charging performance test includes battery slow charging performance test and battery fast charging performance test. Among them, battery slow charging refers to a mode of charging at a lower rate. The battery slow charging performance test is performed at a specific temperature, including low temperature, normal temperature and high temperature environment, focusing on charging capacity, charging energy and charging time. The specific test procedure is as follows. 1) Discharge the battery to the specified discharge cut-off conditions in a…

The purpose of the battery charging performance test is to check the charging ability of the lithium-ion battery in different states. Battery charging performance test includes battery slow charging performance test and battery fast charging performance test. Among them, battery fast charging refers to the mode of charging at a higher current rate. Fast charging is usually the act of charging at high current rates in a low SOC state of the battery system. Battery fast charging performance tests were conducted at designed current rates in low, normal and high temperature environments. The specific test procedure is as follows. 1) Discharge the…
