Abstract

This study aims to evaluate the effectiveness of selected color filter film for demultiplexer construction where only signals with certain wavelengths are allowed to pass through the demultiplexer while the other signal that carrying different wavelengths are absorbed. Characterization testing and analysis is done based on recorded data. Demultiplexer components are characterized by the Same Source at Different Filters (SSDF) and performance of transmitted signal are measured. The developed demultiplexer is effective in short range communication, using low cost components and simple techniques. Communication range for short range communication is maximized by combining wavelengths and send through a single strand of fiber by means of Wavelngth Division Multiplexing (WDM). Only signals with certain wavelengths are allowed to pass through the multiplexer. The rest are absorbed. Several measures are made to ensure efficiency, such as testing and measurement on parametres contributing to loss. Best filters are selected based on their ability to block certain wavelengths while letting others ro pass through efficiently. The blocking feature is important to avoid phenomena of crosstalk occurs in the system.
