1×N self-made polymer optical fiber based splitter for POF-650nm-LED based application

This research focuses on fabrication of 1 by N multimode polymethyl methacrylate based step-index polymer optical fiber (PMMA SI-POF) to be proposed on application based on POF-LED combination as a main transmission media. This self-made bundled-fiber splitters have been fabricated by a perform technique. There several systems available on the market, which able to split or couple optical signals transmitted into some different channels, which are all afflicted with certain disadvantages. But all these solutions have one main disadvantage; they are all too expensive for most of the applications. So the goal of the research is to develop an economical splitter for multipurpose application over PMMA-POF. PMMA material here can be seen as one of the best solution in achieving objectives of the research due to it flexibility and cost efficiency deployment. Characterization of the splitter was reported. Red LED with 650 nm wavelength has been injected into the splitter with the aim to analyze power efficiency of the splitter. A coupling efficiency of 80% has been demonstrated. The device performance can be improved gradually through experience and practice. Main point here is the fabrication process is simple, easy and suitable to be used for household.

Novel fused 1 × N polymer coupler for video surveillance applications

This paper demonstrate novel coupler 1 × N coupler based on polymer optical fiber (POF) was fabricated by handwork fusion method using yellow flame burner and metal tube. A new additional process - twisting-effect removal - is demonstrated to enhance fusion quality. For the purpose of performance characterization, LED fiber source with 650 wavelengths was injected into input fiber while optical power in output fibers was measured by optical power meter. The final results showed that the power-splitting performance of the coupler is satisfying since the insertion loss and excess loss is extremely low (< 7 dB and 0.53 dB, respectively). For video surveillance application, the coupler has potential for high quality video transmission in tree-topology communication system.

Low-cost cascaded 1×4 Polymer Optical Fiber coupler for multiplexing wavelengths

The Wavelength Division Multiplexing (WDM) technology considered as the only solution for increasing demand for higher bandwidth in optical communication, whereby several different wavelengths can carry variety information over one Polymer Optical Fiber (POF). Wavelength Division Multiplexer is an essential component to combine several different wavelengths before all wavelengths are carried together over single POF. In most instances, the conventional multiplexers are afflicted with certain disadvantages and one major disadvantage is that they are costly for most of the POF applications. Thus, the goal of this study is to develop self-fabricated POF coupler as an economical optical multiplexer for WDM transmission over POF. The POF coupler has been fabricated by homemade fusion technique. Red LED with a 650 nm wavelength has been injected into the coupler for the purpose of characterization testing to analyze the level of power efficiency of the coupler. The characterization of POF coupler reveals that the maximum power efficiency could be reached up to 70%. The result exhibits that self-fabricated 1×4 POF coupler has great potential to be applied as optical multiplexer for WDM fiber technology due to the character of high-efficiency and low-cost.

Low-cost fused taper polymer optical fiber (LFT-POF) splitters for environmental and home-networking solution

In visible optical communication over the multimode PMMA fibers, the overall cost of optical network can be reduced by deploying economical splitters for distributing the optical data signals from a point to multipoint in transmission network. The low-cost splitters shall have two main characteristics; good uniformity and high power efficiency. The most cost-effective and environmental friendly optical splitter having those characteristics have been developed. The device material is 100% purely based on the multimode step-index PMMA Polymer Optical Fiber (POF). The region which all fibers merged as single fiber is called as fused-taper POF. This ensures that all fibers are melted and fused properly. The results for uniformity and power efficiency of all splitters have been revealed by injecting red LED transmitter with 650 nm wavelength into input port while each end of output fibers measured by optical power meter. Final analysis shows our fused-taper splitter has low excess loss 0.53 dB and each of the output port has low insertion loss, which the average value is below 7 dB. In addition, the splitter has good uniformity that is 32:37:31% in which it is suitably used for demultiplexer fabrication.
