Designed for Cladding-Pump Applications with CP1500Y Fibercore's CP-IWDM is an integrated isolator and wavelength division multiplexer designed to combine two inputs, high-power multimode pump and singlemode signal, to a single output, SMM900 (105/125) dual-clad pump-signal fiber. With SMM900 the signal is carried in the singlemode core while pump energy is confined within the 105 µm multimode guide. CP-IWDM provides multiplexing and isolation in one small package, thereby simplifying system design and construction. The Fibercore CP-IWDM is designed specifically as a partner for Fibercore's cladding-pump amplifer fiber, CP1500Y, and is ideally suited to systems incorporating Fibercore's other cladding pump component fibers.
