• Hard Polymer Cladding Fiber (HPCF)
  • HOME > PRODUCT > Special Fiber > HPCF


  • Large core fiber with low OH provided by OptoNest is suited for apparatus and systems using 850nm wavelength.
    The hard polymer cladding provides higher tensile strength and greater resistance to moisture than the conventional one. These features together create a fiber widely used in fields of telecommunication and industry, and near-IR spectroscopy. Large core with 200μm~600μm diameter provides an excellent coupling efficiency for data links and connectors.
