ABSTRACT:
A method and apparatus of switching a digital signal from a single input optical fiber to one or more optical fibers comprising the steps of providing an input signal into the input optical fiber, splitting the input optical fiber to form a plurality of split optical fibers each carrying the input signal, amplifying the signal in at least one of the plurality of split optical fibers with a laser activated amplifier, and then attenuating the signal in all of the split optical fibers to produce at least one output signal in one or more of the designated split optical fibers.
