<p>Methods, apparatus, and systems for optical communication channels. A data signal is preconditioned prior to transmission over a fiber optic cable to minimize signal distortion and then transmitted. During reception, the data signal and clock are recovered. A transmitter and transceiver for the optical communication channel may include a data encoder, a partial response (PR) precoder, a pulse filter, and an electrical-to-optical converter to transmit a spread pulse signal over an optical communication channel. The transceiver may further include an optical-to-electrical converter, an automatic gain controller, a matched filter, a PR finite impulse response equalizing filter, a maximum likelihood sequence estimation detector, and a data decoder in order to decode and recover the data. The system includes an optical channel having a channel response, a pulse- shaping transmitter coupled to a first end of the optical channel, and a receiver coupled to a second end of the optical channel.</p> |
