What are the effects of excessively high optical module temperature
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. High temperature impacts several internal parts in different ways: Laser diodes (DFB, VCSEL): Output power and wavelength shift with temperature. Excess heat can push the laser outside its optimal wavelength and reduce optical power. Heavy data traffic, poor heat dissipation, high ambient temperature and component aging easily overheat optical transceiver, resulting in signal degradation, higher bit error rates, shorter transmission distance and even module failure. As the demand for higher speeds grows, the heat generated by optical devices poses increasing challenges.
