Fully compatible across the entire Fibercore Cladding Pump (CP) product range Suitable for WDM and pump-signal combiner components MM105 is designed specifically to complement Fibercore CP product range. An essential component in pump-signal combiners, the 105 µm silica core of MM105 enables the efficient delivery of pump-light into the gain-fiber. The matching of NAs and MM core diameters throughout the Fibercore CP, SMM and MM fibers enhances system efficiency by minimizing interconnection losses.
