Paper Abstract

It is desirable to remove the optical de-multiplexer in reconfigurable optical add/drop multiplexers (OADM) and use coherent receivers instead for channel selection. We set up a wavelength division multiplexed orthogonal frequency division multiplexed system with a raw bit rate of 66.7  Gb/s per channel and a transmission distance of 2,240 km. We show that the OADM can broadcast more than 64 WDM channels to a coherent balanced receiver and can select out a single channel with less than 1 dB of Q-factor degradation.
