    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
