Fiber End Cap (PM or Non-PM)

High Power Fiber End-Caps (FEC) can be used for high power fiber lasers and fiber amplifiers. These devices can be used to reduce the power density at the output of the fiber facet. A mode stripper is incorporated into all Lightel FECs to clean the cladding from unwanted back-reflected light.
