How to distinguish between good and bad optical modules
Optical modules are classified by package type, rate, laser type, center wavelength, mode, connector type, modulation format, transmission distance, interface operation mode, and pluggability. These classifications determine compatibility, performance, and application. There are so many factories providing optical modules at big difference price for the same module, so how to judge the quality? 1. The optical transceiver module must comply with the MSA multi-source agreement with CE, ROHS, FCC certification, etc. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. As illustrated in the Optical Module.
