Bidirectional link mock-up for avionics applications

Abstract

We demonstrated an avionic-representative link at 1 Gb/s with a span of 100 m. The performances are compliant with IEEE GbE specifications and tolerant to ldquoproduction breaksrdquo. In order to validate the reliability of this solution, additional connectors influence on the link performances need to be checked. Also, temperature in the [-40, +85degC] range, and vibrations constrains need to be tested. At term, we expect the transceiver to be improved to include the MMF coupling function, which will help controlling the return losses. Avionic standards, namely ARINC 800 requirements, shall finally be taken into account in link specification.
