An apparatus includes a multi-channel optical transmitter and an all-optical transmission line. The multi-channel optical transmitter is configured to produce optical data streams having double-sideband formats in each of a series of channels. The all-optical transmission line has a sequence of spans of transmission optical fiber and one or more sequences of optical bandpass filters and is configured to receive from the optical transmitter optical data pulses in the series of channels. One of the sequences of optical bandpass filters is configured to pass one of the sidebands and to block the other of the sidebands of the optical data stream in an associated one of the channels and is also configured to block one of the channels adjacent to the associated one of the channels.
