Abstract
A transceiver for fiber optic communications. The transceiver can include a transmitter module having a transmitter host interface configured to receive an input host signal; a transmitter framer configured to frame the input host signal and to generate a framed host signal; and a transmitter coder configured to encode the framed host signal to generate an encoded host signal for transmission over a communication channel. The transceiver can also include a receiver module having a bulk chromatic dispersion, fiber length estimation, and coarse carrier recovery circuit configured to equalize a digital input ingress signal to generate an equalized ingress signal; a receiver framer configured to frame the equalized ingress signal to generate a framed ingress signal; and a receiver host interface configured to output the framed ingress signal. The receiver host interface is compatible with a framing protocol of the receiver framer.
