摘要： A flexible grid optical transceiver communicatively coupled to an optical network includes a coherent optical transmitter configured to generate a transmit signal at a first frequency/wavelength center and spanning a first one or more bins of optical spectrum; and a coherent optical receiver configured to receive a receive signal at a second frequency/wavelength center and spanning a second one or more bins of optical spectrum, wherein a size of each of the first one or more of bins and the second one or more of bins is based on a required roll off of a wavelength selective component in the optical network.

摘要： A flexible grid optical transmitter communicatively coupled to an optical network includes a coherent optical transmitter configured to generate a signal at a respective center frequency on an optical spectrum and spanning n bins about the respective center frequency, wherein n is an integer greater than 1, wherein the respective center frequency and the n bins are utilized to perform Operations, Administration, Maintenance, and Provisioning (OAM&P) functions. The respective center frequency and the n bins are specified to the coherent optical transmitter by a management system for the OAM&P functions. Each of the n bins can include a same arbitrary size, and the arbitrary size can be greater than or equal to 1 GHz and less than or equal to 12.5 GHz.
