چکیده (انگلیسی):

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.
