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.
