Clock and data recovery (CDR) has two core tasks: recovering the clock signal and recovering the data signal. Through processes like re-amplification, reshaping, and retiming, it eliminates jitter and distortion caused during transmission, ensuring the receiver accurately interprets data. In an era where information travels at the speed of light, optical modules, as the "bridge" of network communications, undertake the important task of converting electrical signals and optical signals, allowing data to be transmitted rapidly in optical fibers. Behind the stable operation of optical. Introduction to Optical Module CDR CDR stands for Clock and Data Recovery. In optical modules, CDR is a very ...
