Analysis of Optical Receiver Module
As signals travel in a fiber, they are attenuated and distorted, and it is the function of the receiver circuit at the other side of the fiber to generate a clean electrical sig. In other words, any noise added to a signal at the first stage will be amplified by subsequent stages, and thus it will be hard (if not impossible) to remove. As discussed earlier, an optical receiver typically requires a clock and data recov-ery (CDR) circuit to extract the clock signal from the received serial data. In practice, TIAs also need to be modified to accommodate burst mode traffic.
