Cost has been the barrier to using fiber optic links in low datarate, short haul applications of less than 5 Mbaud and up to 150 meters. New fiber optic links using plastic (acrylic) fiber, however provide a cost effective alternative to coaxial cable and twisted wire pairs in such applications. The large core fibers with a diameter of 1 mm do not require the tight alignment tolerances needed in glass- or plastic clad silica fibers for reasonable light coupling at the source and detector interfaces. Looser alignment tolerances also let manufacturers package transmitters and receivers in plastic housings, thus lowering component costs.
