Abstract:
An optical transceiver may include an optical transmitter and an optical receiver. The optical transmitter and receiver may each include a grid including one or more lanes spaced apart. Each lane may correspond to a predetermined optical signal, or wavelength. The optical transmitter may include one or more sets of lasers to output one or more optical signals corresponding to the grid. Each set of laser may output a set of optical signals. Each set of lasers and, therefore, each set of optical signals may have a different passband. For example, the multiplexing and/or demultiplexing architecture may have a wide passband for the first set of optical signals and a narrow passband for the second set of optical signals. The narrow passband may be determined based on the space between two wider passbands.
