Abstract
Abstract The implementation of three channels wavelength division multiplexing (WDM) network using a low cost and all POF components are developed. A low cost and high performance of 1x3 POF fused coupler/splitter using POF polymethyl methacrylate (PMMA) is fabricated as the multiplexer/de-multiplexer. Three visible LED light source transmitters; 470 nm, 520 nm and 650 nm are utilized in sending three data inputs; the CCTV and DVD video and audio signal. The optical lights are multiplexed into a single POF link and de-multiplexed back at the receiver end. The unwanted wavelengths are performed using thin color film filter before the receivers. With link margin 5 dB, the maximum POF link length is 25 meters which is suitable for informatics, infotainments, triple play in the field of last miles communications.
