Claim:
1. A multiplexed optical communication system comprising: a transmission optical fiber having a first end, a second end and a longitudinal axis; at least one TDM multiplexer, able to time division multiplex a plurality of individual input baseband signals, and having an output comprising a resulting time division multiplexed data stream; a first set of WDM multiplexers comprising at least one WDM multiplexer each WDM multiplexer comprising: wherein each TDM multiplexer is in electrical communication with one optical source of said first set of WDM multiplexer optical sources, such that each time division multiplexed data stream is communicated to a unique optical source; wherein each WDM output optical fiber has a longitudinal axis and is placed in proximity to said first end of said transmission optical fiber, and wherein said longitudinal axis each of said WDM output optical fibers is disposed at an angle θ said multiplexed optical communication system further comprising a WDM demultiplexer in communication with said transmission fiber and able to separate each unique optical wavelength of each optical source, producing an SDM optical output signal onto an optical fiber, and wherein each of said SDM optical output signals is communicated to a unique SDM demultiplexer; wherein each unique SDM demultiplexer comprises photodetectors for separating each SDM optical signal from the other SDM-separated optical signals and converting each SDM optical signal to an electrical signal, producing a unique electrical TDM signal output for each SDM-separated optical signal, wherein each of said unique TDM signal outputs is communicated to a unique TDM demultiplexer able to demultiplex each TDM signal outputs, and also able to reconstruct each of said individual input baseband signals, producing a unique electrical output data stream for each individual input baseband signal.
