Plastic Optical Fiber (POF) is an interesting alternative optical communication channel to the Glass Optical Fibers (GOF) for some applications which do not require to cover long distances, such as home or automotive networking. However, the reduced low bandwidth of the POF channel imposes big limitations in the maximum data bitrate that can be transmitted through this medium. Consequently, advanced data communication techniques, such as channel equalization, data error correction or data signal modulation, has to be applied to get data bitrates above 1 Gbps. This lecture shows an overview of the use of Plastic Optical Fiber (POF) as a medium for optical data communications and the techniques needed to get high speed data bitrates over POF
