摘要： An apparatus comprises an uncooled laser; a splitter coupled to the laser; a first wavelength component coupled to the splitter; a local oscillator (LO) port coupled to the first wavelength component; a modulator coupled to the splitter; a second wavelength component coupled to the modulator; and a signal port coupled to the second wavelength component. A method comprises emitting an input light; splitting the input light into a first local oscillator (LO) optical signal and a first unmodulated optical signal; modulating the first unmodulated optical signal using polarization-multiplexed, high-order modulation to produce a first modulated optical signal; transmitting the first LO optical signal to a first duplex fiber; and transmitting the first modulated optical signal to a second duplex fiber.

摘要： An optical transceiver comprises a transmitter configured to transmit a first signal, and a receiver coupled to the transmitter and configured to receive a first compensation, wherein the first compensation is based on a pattern-dependent analysis of the first signal, and provide the first compensation to the transmitter, wherein the transmitter is further configured to compensate a second signal based on the first compensation to form a first compensated signal, and transmit the first compensated signal. An optical transmitter comprises a digital signal processor (DSP) comprising a compensator, a digital-to-analog converter (DAC) coupled to the DSP, a radio frequency amplifier (RFA) coupled to the DAC, and an electrical-to-optical converter (EOC) coupled to the RFA. An optical receiver comprises an optical-to-electrical converter (OEC), an analog-to-digital converter (ADC) coupled to the OEC, and a digital signal processor (DSP) coupled to the ADC and comprising a calibrator.
