TITLE: Cost-Effective Solution for WDM Multimode Transmission in Small World Communication

ABSTRACT：

Polymer Optical Fibers (POFs) replace traditional communication media such as copper and glass step by step within short distance communication systems, mostly because of their cost-effectiveness and easy handling. POFs are used in various fields of optical communication, e.g. the automotive sector or in-house communication. The current “state of the art” are single mode communication systems. These systems use only one wavelength for communication, which limits the bandwidth. For future scenarios, this traditional technology is the bottleneck of bandwidth (e.g. for HDTV with IP-TV).  One solution to surpass this limitation is to use more than one wavelength over one single fiber, a technique known as WDM (wavelength division multiplexing). This multiplexing technology requires two more technical key elements: a multiplexer, which combines the multi-wavelengths signals into one fiber and a demultiplexer at the end of the network to separate the colored signals. This presentation discusses the overall POF technology for small world communication from device fabrication, device types, configurations and applications. Our solution supports the basis of a wavelength division multiplex (WDM) system in the visible spectrum. Discussion will focus on the technologies that have been developed in our laboratory concerning user friendly approach, ease of maintenance, safety and high-performance solution.
