The working temperature of the optical module has a greater impact on the use of optical modules, if the working temperature of the optical module is too high or too low, there will generally be a decline in optical power, low sensitivity, poor eye. The working temperature of the optical module has a greater impact on the use of optical modules, if the working temperature of the optical module is too high or too low, there will generally be a decline in optical power, low sensitivity, poor eye. The working temperature of the optical module has a greater impact on the use of optical modules, if the working temperature of the optical module is too high or too low, there will generally be a decline in optical power, low sensitivity, poor eye diagrams, in addition to accelerating the aging of. The performance of an optical module is influenced by a variety of factors, including temperature. If an optical module operates at too high or too low temperature, it can negatively impact its performance and lead to system failure. If these situations occur, it may be caused by the following conditions: ②Used optical module: The performance of the second-hand optical module has not reached the factory standard when it is used. In addition, it will accelerate the.
