Abstract
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.
Highlights
As telecommunication traffic increases due to the rapid growth in use of phones, faxes, computer networks and the internet, fiber capacity will have to keep pace
Before the concept of Wavelength Division Multiplexing (WDM) being applied in optical technology of communication system, a single channel is used for sending data over polymer optical fiber, but this technique has a limited bandwidth
At the end of the system, LED light source has been multiplexed through single optical fiber and has separated by demultiplexer
Summary
As telecommunication traffic increases due to the rapid growth in use of phones, faxes, computer networks and the internet, fiber capacity will have to keep pace. The Wavelength Division Multiplexing (WDM) technique increase the value added and arises as a promising technology solution to realize very high capacity long distance transmission systems by exploiting the wide bandwidth available in optical fiber. Because of the dramatic increase in capacity of optical communication using WDM, there has been an increasing interest in the development of particular devices to mange a number of wavelengths.
