TRANSPONDER AGGREGATOR WITHOUT WAVELENGTH SELECTOR COLORLESS AND DIRECTIONLESS MULTI-DEGREE ROADM NODE
摘要
<p>A method for transponder optical channel selection of optical signals from a transponder aggregator includes choosing wavelength division multiplexing channels to be dropped from a transponder aggregator receiving optical input signals, splitting all dropped wavelength division multiplexing channels into at least one transponder having a coherent receiver and transmitter, and tuning a local oscillator laser of the coherent receiver to a wavelength of one of the all dropped wavelength division multiplexing channels for selecting one of the all dropped wavelength division multiplexed channels.</p>
