If you know the model or type of an optical module, you can view the section "Pluggable Modules for Interfaces" in the Hardware Description to look up parameters of the optical module, including the center wavelength, transmission distance, fiber types supported, receive optical.

SFP (Small Form-factor Pluggable) optical modules are compact, hot-pluggable transceivers that enable network equipment to connect seamlessly to fiber and copper links. The five parameters have basically decided whether the opti al module can work normally. If one of the five parameters is abnormal, ONU registration will be abnormal or packet nt are all for the PON port. The light reception power is for an ONU, that is, it is for a. Optical module is a key optical fibre communication device, its main function is to convert electrical signals into optical signals and transmit data through optical fibre media. Theoretically, the greater the optical power, the farther the optical signal. The optical module, known as Optical Transceiver in English, is a general term for various module categories, including optical receiver modules, optical transmitter modules, optical transceiver modules, and optical forwarding modules.
