Plastic optical fiber (POF) or polymer optical fiber is an optical fiber that is made out of polymer. Similar to glass optical fiber, POF transmits light (for illumination or data) through the core of the fiber. Its chief advantage over the glass product, other aspect being equal, is its robustness under bending and stretching.
Hard-clad silica (HCS) or polymer-clad fiber (PCF) is an optical fiber with a core of silica glass (diameter: 200 μm) and an optical cladding made of special plastic (diameter: 230 μm). In contrast to all-silica fiber , the core and cladding can be separated from each other.
Optical fiber is an intrinsic part of the light-transmitting concrete building product LiTraCon. Optical fiber can also be used in structural health monitoring. This type of sensor can detect stresses that may have a lasting impact on structures. It is based on the principle of measuring analog attenuation.
In telecommunications and fiber optics, a plastic-clad silica fiber or polymer-clad silica fiber (PCS) is an optical fiber that has a silica-based core and a plastic cladding. [1] The cladding of a PCS fiber should not be confused with the polymer overcoat of a conventional all-silica fiber.
Polymer optical fibers have generated increasing interest in recent years. [ 20 ] [ 21 ] Because of low cost, ease of handling, long wavelength transparency, great flexibility, and biocompatibility, polymer optical fibers show great potential for short-distance networking, optical sensing and power delivery.
Generally, such fibers are constructed by the same methods as other optical fibers: first, one constructs a "preform" on the scale of centimeters in size, and then heats the preform and draws it down to a much smaller diameter (often nearly as small as a human hair), shrinking the preform cross section but (usually) maintaining the same features.
