A size-expandable and bandwidth upgradable opto-electronic circuit switch (10) and corresponding methodology for full broadcast routing of a plurality of signals with 100% non-blocking are provided. The opto-electronic circuit switch (10) includes at least two input transmitters (22) for receiving electrical input signals and for converting these electrical signals into a corresponding optical input signal, such that each optical input signal is at a different wavelength carrier. Next, a multiplexer (24) is used to combine these optical signals into a single optical input using wavelength division multiplexing, a fixed equalizer (25) provides the same gain response among all signals, and an amplifier (26) optically amplifies this optical signal received from the multiplexer. A splitter (28) receives this amplified optical signal from the amplifier (26) and transmits it as a plurality of optical output signals to at least two optical receivers (30). Each optical receiver (30) selects one of the optical input signals from the optical output signal by its wavelength, and then converts this selected signal into an electrical output signal. Optional RF and digital subsystems are also provided to maximize the bandwidth utilization and further increase the number of input and output ports.
