ABSTRACT:
A method of switching from a single input optical fiber to one or more output fibers comprising the steps of providing an input signal into the input optical fiber, splitting the input signal and the input optical fiber to form a plurality of optical fibers and a plurality of split input signals each of the optical fibers carrying a single one of the plurality of the split input signals, attenuating the plurality of the split input signals, amplifying at least one of the plurality of the split input signals with a laser activated amplifier to produce at least one output signal, and outputting the at least one amplified split input signals through corresponding at least one output fibers.
