Paper Abstract

Stricter requirements for data transmission, such as harness weight, data bandwidth and attenuation, have caused a rising demand for fiber optical (FO) solutions in the space market. The market is in need of solutions that are able to accommodate a high number of fibers, be highly customizable and have a low assembly, integration and test (AIT) time.

In this context we present the development of the Fiber Optical Flexible Routing Assembly (FOFRA) under the ARTES 5.2 programme. The FOFRA is a thin and flexible optical circuit board that offers a protected layout environment for fibers in a systematic high-density pattern. Today, the FOFRAs are produced for jet fighters and other applications.

Routing a larger number of fibers is a time-consuming and meticulous task which requires an optimized systematic design with a high routing precision. A fiber optical routing machine has been developed together with a routing software for this application. It has been demonstrated that these tools can produce a large variety of FOFRAs regarding size, shape, material and fiber I/O interface. The FOFRAs can be manufactured using materials with good space experience. The MT-ferrule has been selected as the preferred interface option. Several variations of FOFRAs will be presented.
