How to separate transmit and receive signals in an optical module
This integration is achieved through the use of wavelength division multiplexing (WDM) filters, which separate the transmit and receive wavelengths within the same fiber. In the era of 5G, AI, and high-speed data centers, optical modules serve as the core bridge for converting electrical signals to optical signals (and vice versa), enabling fast, reliable data transmission across networks. Among various optical module form factors, SFP (Small Form-Factor Pluggable). These modules play a vital role in transmitting and receiving optical signals. At the transmit end of the WDM system, N optical transmitters work on N different wavelengths respectively. In optical fiber technology, an optical fiber link is utilized to transfer analog or digital data in light frequency form via a cable with a highly reflective central core. The role of the highly reflective central core is to act as a light guide for the transfer of light through it through.

Why is there no signal from the optical module when the fiber optic cable is too long
If the receiving power is low (RxPower Low), the signal received is too weak, possibly due to excessive transmission distance or fiber damage.
