Hard clad silica optical fiber
Hard-clad silica optical fiber (short HCS fiber or HCSF , dt. Hard-coated light waveguide ), and polymer clad silica fiber or plastic clad silica fiber (short PCS fiber or PCF fiber ) denotes an optical fiber with an optical core of Quartz glass and an optical jacket made of a special plastic z. B. Tefzel ( ETFE ), core and cladding do not form an inseparable unit as is the case with quartz / quartz fibers (English silica-silica fiber ).
Due to their medium bandwidth and transmission rate of <100 Mbit / s, HCS fibers are suitable for medium ranges of up to two kilometers, e.g. B. in local networks of buildings or in industry. The general rule here is: the higher the attenuation, the lower the range.
For comparison: plastic fiber-optic cables (also POF - polymer optical fibers ) have a data rate of <1000 Mbit / s. The maximum range is around 100 meters. In contrast, fiber optic cables have very high bandwidths and transmission rates up to GBit / s. With fiber optics, ranges of more than 10 kilometers can be achieved. In terms of range, an HCS fiber therefore moves between POF fiber-optic cables and multi- or singlemode fibers .
For HCS cables there are (HCS-F-SMA) and various HFBR plugs, as well as FO5, FO7, SC and FC / PC plugs.
