Media polymer optical fibers

Since all commercially available POF have been of the step-index (SI) type, the modal dispersion limits the possible bit rate of POF links to less than 100 megabit per second (Mb/s). Because of this, it has been thought that POF cannot be utilized for high speed transmission medium. Recently, however, we proposed a large core, low loss, and high bandwidth graded-index polymer optical fiber (GI POF) (7,2) for the first time and we confirmed that 2.5 Gb/s signal transmission for 100 m distance was possible in the GI POF (2,5). 

Recent work has investigated conductive polymers [69,70], sol-gels [71], and chemoresponsive dyes [72] for use as the gas-sensitive transduction medium in fiber optic sensors. In general, fiber optic sensors can be divided into two different sensing architectures extrinsic and intrinsic. If the transduction of the chemical signal into an optical signal occurs within the fiber...
