Abstract
One embodiment of the present invention provides an optical transceiver. The transceiver can include a transmitter and a receiver. Each of the transmitter and receiver can include a plurality of space-division multiplexing (SDM) channels configured to transmit or receive spatially separated optical signals. A respective SDM channel can include a plurality of wavelength channels and an optical wavelength multiplexer or demultiplexer configured to multiplex or demultiplex optical signals to or from the plurality of wavelength channels.
