400g optical transceivers play a vital role in the process of constructing a 400G network system. It is used for photoelectric conversion with a transmission rate of 400Gbps. The electrical port side employs 8 channels of 53Gbps PAM4 electrical signals, packaged in OSFP or QSFP-DD formats. Optical wavelength categorizes 400G optical transceivers into multi-mode (MM) and single-mode (SM), transmission distance classifies them as SR, DR, FR, and LR, and modulation methods usually PAM4.
