Buying Fiber Couplers

Some fiber couplers can combine inputs from several input fibers (e.g., pump and signal) to produce one or more outputs. Others are devices for coupling light from free space into a fiber. Fiber couplers are used in a variety of applications including telecommunications, sensor networks, and laser systems.
