For coupling to LED and laser sources, these larger core diameter fibers connect more efficiently and less expensively than Single-mode or Graded-Index fibers. For medical applications, they are USP Class VI non toxic, biocompatible, and sterilizable. Part of the HCS fiber family, the 200 and 400 µm sized fibers are compatible with crimp and cleave termination.
