Plastic-clad silica fiber


In telecommunications and fiber optics, a plastic-clad silica fiber or polymer-clad silica fiber is an optical fiber that has a silica-based core and a plastic cladding. The cladding of a PCS fiber should not be confused with the polymer overcoat of a conventional all-silica fiber.

Benefits

The main applications of plastic-clad silica fiber are industrial, medical or sensing applications where cores that are larger than those used in standard data communications fibers are advantageous.

Limitation

PCS fibers in general have significantly lower performance characteristics, particularly higher transmission losses and lower bandwidths, than all-glass fibers.
