Abstract

Fiber-optic data links enable high-speed
communications onboard satellites and spacecrafts. VTT has
developed ruggedized optical transceivers for multi-gigabit
interconnections in harsh environments, including also multi-lane
links. The transceiver developed for the SpaceFibre optical
physical layer supports full-duplex communication up to
6.25 Gb/s so far and is upgraded to 10 Gb/s. The hermetic
packaging approach results in a compact and robust transceiver.
It has passed stringent mechanical and thermal tests, as well as
gamma radiation tests. Recently also heavy-ion and proton
single-event-effect radiation tests were performed demonstrating
that the transceiver is latch-up free and not sensitive to single
event functional interrupts or destructive effects. Moreover, the
effect of single bit-errors or error strings induced by energetic
particles is estimated negligible in the in-orbit applications and
with the normal encoding and error-correction schemes
