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.
