The cost effective demultiplexer based on POF is reported in this study. The demultiplexer is fabricated by combining optical splitter with the suitable filter for wavelength selection. Therefore this study we 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. Power reduction analysis has been carried out for special filter used in the configuration. Characterization testing and analysis is done based on recorded data. Demultiplexer components are categorized by Same Filter Different Sources (SFDS) scheme and then performance of transmitted signal by the presence of interference is studied. Demultiplexer developed is effective in short range communication, using low cost components and simple techniques. Communication range for short range communication is maximized. 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 parameters contributing to loss. Best filters are selected based on their ability to block certain wavelengths while letting others or pass through efficiently.

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.
