In this paper, we report experimental demonstration of a polymer optical fiber (POF) based solutions in wavelength division multiplexing (WDM) network and some effects on placement of interference filters as a demultiplexer for the system. Optical signals with different wavelengths can carry different information through one fiber. All the wavelengths will be multiplexed and have to be split at the receiver to regain the information. The main idea is to develop a demultiplexer by employing the principle of WDM. The transmitter will emit three different sources (λ = 470 nm, 520 nm and 665 nm) of light and be multiplexed into single white light. However, the light has to be separated at the receiver in order to recover back the information by using demultiplexer. In this experiment, step index POF fused optical splitter is used to realize the concept of multiplexer. A handmade demultiplexer is realized by using color films for the filter. The specialized designed interference films are used to filter out any other wavelength (color) that is not within the range. It will only allow one wavelength to get through the filter and thus conveyed the data carried at the receiver. Several readings using optical power meter are taken to record the losses and power outputs for efficiency and characterization process. LEDs are injected through the fiber and the demultiplexed signals at the end receiver are analyzed. The efficiency of the demultiplexer is about 70%. Fabrication of the demultiplexer using color filters and epoxy-resin is simple although it needs meticulous concentration for certain parts. The performance shows that the system can be used for short distance data communication in larger bandwidth and faster data rate .

The implementation of three channels wavelength division multiplexing (WDM) network using a low cost and all POF components are developed. A low cost and high performance of 1x3 POF fused coupler/splitter using POF polymethyl methacrylate (PMMA) is fabricated as the multiplexer/de-multiplexer. Three visible LED light source transmitters; 470 nm, 520 nm and 650 nm are utilized in sending three data inputs; the CCTV and DVD video and audio signal. The optical lights are multiplexed into a single POF link and de-multiplexed back at the receiver end. The unwanted wavelengths are performed using thin color film filter before the receivers. With link margin 5 dB, the maximum POF link length is 25 meters which is suitable for informatics, infotainments, triple play in the field of last miles communications.

Injection molding of a WDM system for POF communication
Proceedings - Electronic Components and Technology Conference
Polymer Optical Fibers (POFs) possess some advantages compared to copper and glass fibers. Primarily, POFs are inexpensive, space saving, easy to handle, and not susceptible to electromagnetic interference. Therefore, POFs are a reasonable alternative in short distance data communication. Due to their specific advantages POFs are applied in a wide number of applications. The main applications include automotive communication systems and in-house-networks. Currently, only one channel is used for data transmission, which limits the bandwidth. To improve the data transmission rate over POF, the Wavelength Division Multiplexing (WDM) technique is used. Therefore an integrated Multiplexer (MUX) and Demultiplexer (DEMUX) are designed and developed in order to use multiple channels. To make the elements available to a broader market, a cost-effective mass production of MUX and DEMUX is needed. Injection molding is the only technology that allows this. However, designing the elements with r...
