Abstract

Problem statement: Huge capacity for data transmission and bandwidth are becoming a need nowadays. High cost of implementation using optical fibers prevents utilization of the technology as wide as possible. Approach: Wavelength Division Multiplexing (WDM) was a technique that offers the solution for providing better bandwidth. WDM technique allows several signals that have different wavelengths to be transmitted in a single optical fiber to the receiver without any external interference or internal interruption between the signals transmitted simultaneously. WDM technique requires splitting of signals at reaching the receivers and one of the solutions presented in this study will provide a method using inexpensive filtering device that functions efficiently as a demultiplexer that can be develop without any complication. There were a lot of systems that provided demultiplexing techniques in the industry; all the systems are expensive to be implemented. Here the study provides an effective and easy to construct demultiplexer by using colored thin films. The WDM-POF system studies the performances of thin-films to be used as demultiplexer and red thinfilms will be focused. Results: In theory, the thin-films will filter out any undesired signals that pass through the fiber and the desired signal will be carried to the end-receiver. The effectiveness of each red thin- films were characterized by analyzing the insertion losses (dBm) and power output (μW). Characterization analysis in this study includes the characterization test of using the same sources towards different types of red thin-films to obtain the best film that could filter out any undesired wavelength and let only the desired wavelength to be transmitted at high percentage. An initial stage of selecting different colored films by analyzing the energy spectrum distribution curves for the potential red thin- films will then be characterized where red, blue and green LED sources were injected through the films. Small insertion loss of the signal transmitted for the same wavelength of the source and high power output will be preferred. High insertion loss and small power output are preferred for filtering out the undesired wavelengths. Comparison and characterization analysis through the samples and graph simulations provides the efficiency of the thin films that were used in the optical WDM-POF short-haul communication system. Conclusion: Optimum performance can be observed through the end-receivers that have been connected to the device developed such as the Ethernet connectivity and the result of video image received the signals as desired.
