Abstract
As spacecraft begin to unlock the potential of fiber optic systems for spaceflight applications, system level bit error rates (BER) become of great concern to the system designer. Fiber optic data busses running up to 1 Gbps data rates require an uncorrected BER to meet system specifications. With emerging high speed and low power devices such as 3 V CMOS and GaAs ICs being utilized in the system design to interface the electronic subsystems to the fiber optics, the BER contribution of these emerging technology devices in the space Single Event Effect (SEE) arena may outweigh that of the fiber optic components. We present data on several emerging technology devices and the implication of their usage in fiber optic systems in the space SEE environment.
