Abstract: A coherent receiver comprises an ingress signal path having an ingress line-side interface, and an ingress host-side interface. The ingress signal path is configured to receive an analog signal vector at the ingress line-side interface, to demodulate the analog signal vector, and to output a digital data signal Fat the ingress host-side interface. The coherent receiver also comprises clock and timing circuitry configured to receive a single reference clock signal and to provide a plurality of modified ingress path clock signals to different components of the ingress signal path, the plurality of modified ingress path clock signals derived from the single reference clock signal and the plurality of modified ingress path clock signals having different clock rates. The receiver, transmitter, or transceiver can operate in a plurality of programmable operating modes to accommodate different modulation/de-modulation schemes, error correction code schemes, framing/mapping protocols, or other programmable features.

Abstract: Methods of operating an optical communication system in coherent optical transmissions for metro applications. Relative to conventional solutions, the optical communication system can be implemented with reduced cost and can operate with reduced power consumption, while maintaining high data rate performance (e.g., 100 G). Furthermore, a programmable transceiver enables compatibility with a range of different types of optical networks having varying performance and power tradeoffs. In one embodiment, the optical communication system uses 100 Gb/s dual-polarization 16-point quadrature amplitude modulation (DP-16QAM) with non-linear pre-compensation of Indium Phosphide (InP) optics for low power consumption.

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.
