In this paper, we describe the development of a diffuse infrared optical backplane technology for small satellites. After an overview of the system architecture and previous work, we discuss the design and implementation of a radiation tolerant interface ASIC. This ASIC, which is fabricated in a silicon-on-sapphire process, contains test circuits for the interface between the photonic components (VCSEL and PiN photodiode) and the transceiver's digital logic. In addition, we describe further work towards the improvement of our system's range and the creation of a fully integrated digital node.
