摘要： Embodiments for optical communication are provided in which tunable receiver selects and demodulates a first channel of a WDM signal. An example receiver includes a tunable local oscillator for generating a local oscillator signal approximately centered at a first channel wavelength. An optical hybrid of the receiver receives at a first input a wavelength-division-multiplexed (WDM) signal with a M-ary modulation scheme, wherein M is an integer greater than 2, and at a second input the local oscillator signal. A plurality of detectors detect in-phase and quadrature components of the first channel wavelength output of the optical hybrid, which are digitizing by a plurality of analog-to-digital converters. A digital signal processor processes the digitized in-phase and quadrature components in order to recover data carried by the first channel of the WDM signal.

摘要： A multi-degree cross connector system, an operating method and an optical communication network using the same are provided to reduce system costs and simplify a structure by performing optical/electric conversion and electric/optical conversion only for a signal which will be dropped/coupled, increase extensibility of a network by reproducing a degradation signal, and use a bandwidth efficiently by grooming an electric digital hierarchy unit signal of low speed. A multi-degree cross connector system comprises optical couplers(500,500-1,500-2,500-3), WSSs(Wavelength Selective Switches)(510,510-1,510-2,510-3), demultiplexers/multiplexers, an electrical cross connection/grooming switch(520), an optical transceiver(530) and a control system. The optical couplers drop an inputted multi-wavelength optical signal into plural paths. The WSSs extract at least one single wavelength optical signal from the dropped optical signal and transmit the extracted signal to at least one output port or extract at least one single wavelength optical signal from the dropped optical signal inputted through at least one port and transmit the extracted signal to one output port. The cross connector control system controls wavelength components of an optical signal inputted into the WSS or outputted wavelength components.
