A multiple channel optical multiplexing/demultiplexing system utilizes a beam splitter to divide a single multi-wavelength beam of optical energy into two multi-wavelength beams, or to combine a plurality of multi-wavelength beams into a single output beam. In the demultiplexing configuration, a pair of demultiplexers are configured to receive and separate the two multi-wavelength beams into a plurality of wavelength channels. The two multi-wavelength beams are thus demultiplexed in parallel, allowing greater efficiency by avoiding excess beam attenuation. The individual demultiplexers can be incorporated into a single unitary device or can be optically interconnected as separate parts. Alternatively, the demultiplexing system can use multiple beam splitters to divide a single input multi-wavelength beam into a plurality of multi-wavelength beams for parallel demultiplexing in a plurality of demultiplexers.
