A multi-mode wavelength-division multiplexing (WDM) receiver includes a receiver head to receive a free-space optical (FSO) signal. A multi-mode demultiplexers (demux) is coupled to the receiver head via a multi-mode fiber to generate a number of optical signals based on the FSO signal. A number of...
