Performance modeling and analytical verification of POF transmissive star couplers for avionics system applications

Abstract

We discuss the performance modeling of transmissive star couplers based on plastic optical fibers which are designed for avionics system applications. Simulation is based on a commercial software tool where the concept of supermodes is introduced. Results are validated using an analysis which expands on prior work based on multimode couplers in polymers.

Transmission Performance of Plastic Optical Fibers Designed for Avionics Platforms

“…P LASTIC optical fibers (POF) have become a rapidly emerging media for transporting high-speed at low cost in the short-haul environment. Applications in automobiles and in-house systems and networks [1]- [3] have led this development and the airplane is the latest arena where they are becoming a serious alternative to glass fibers [4], [5]. More recently, POF has been suggested for the avionic platforms [6] by our industrial collaborator The Boeing Inc. Their increased diameter allows higher tolerance to vibrations and to dust particles that can totally obstruct light propagation in glass fibers; airplane cargo bays are generally dusty environments.…”

Characterization of a Y-Coupler and Its Impact on the Performance of Plastic Optical Fiber Links

“…As a result, the need to design and manufacture POF-specific components, and particularly passive devices, arises. In this context, multi-port couplers are key elements to implement different layouts that require combining or splitting optical signals, whereas similar designs are needed for sensor applications and for power monitoring in network management and testing [1][2][3]. Thus, depending on their function, several coupler designs based on different technologies have been developed: waveguide plates, injection molding, fused-tapered, thermally bended/glued or misaligned fibers and beam-splitter cubes [4][5][6][7][8].…”
