An
optical fiber that has a
silica -based
core and a plastic
cladding . Note 1: The cladding of a PCS fiber should not be confused with the polymer overcoat of a conventional all-
glass fiber. Note 2: PCS fibers in general have significantly lower performance characteristics, i.e., higher
transmission losses and lower bandwidths, than all-glass fibers. Synonym polymer-clad silica fiber .
