Claim Text:
1. A fiber optical apparatus comprised of a multiplicity of optical circuits each optical circuit comprised of an arrayed waveguide grating (AWG) operating in the demultiplexing mode having a multiple n of optical channel outputs that are individually connected to an equal number of 1×1 optical switches which are, in turn, connected to either an optical splitter/combiner operating in the combiner mode or another arrayed waveguide grating (AWG) operating in a multiplexer mode, such that each optical circuit is suitable for demultiplexing wavelength division multiplexed (WDM) optical channels on an each input optical fiber and directing one demultiplexed channel at a time over an associated output optical fiber with all such output fibers from all optical circuits connected to a common multiple optical switch which is, in turn, connected to a multiplicity of output ports that connect to optical splitter/combiners that are all operated in the splitter mode for purposes of replicating and rebroadcasting various optical channels.
