Examination of Plastic Filter on 1×N Fused-Taper-Twisted Polymer Optical Fiber Demultiplexer

Problem statement: In this study we propose the examination of the plastic filter on 1×3 POF demultiplexer. Approach: Three wavelengths are injected to the device which then split into three branches. Each branch is filtered by using specific color according to the pass through wavelength. Results: The developed demultiplexer is tested by transmitting signals through the polymer fiber-optic (10 meters length) and the resultingsignalis detectedusing anoscilloscope. The detectedsignalhas anoutputpower of1.68V from peaktopeak. Conclusion: From the results, it is shown thatthe WDM system has solved this problem by increasing the bandwidth in order to send larger data in faster and effectively way. System performance that use WDM concept has influenced this method especially in short-range communication system.
