MPTB Radiation Effects Study on the DR1773 Fiber Optics Data Bus

We present a description of the Microelectronics and Photonics Test Bed (MPTB) Dual-Rate 1773 (DR1773) Fiber Optics Experiment, the radiation hardening techniques utilized, as well as the associated radiation ground test results and analysis. A large increase of single event upset (SEU) hardness was observed beyond expected simple photodiode models. I. Introduction and Background The NASA Goddard Space Flight Center (GSFC) along with the Naval Research Laboratory (NRL) have been at the forefront of the space community in terms of the use of fiber optic systems in the space radiation environment.
