Radiation hardening of advanced fiber optic systems for space missile and avionic applications

We describe performance testing results of a quad transceiver module developed for harsh environment applications. This 850 nm VCSEL-based transceiver operates over 4 independent transmit and receive channels using multi-mode fiber. We present characterization of performance and built-in-test (BIT) features over temperature as well as initial Total Dose and Single Event Upset radiation data.
