A line of radiation-resistant optical modules with a bandwidth of up to 28 Gbps per lane consists of the SpaceABLE28 transceiver and the SpaceCONEX28 board-edge, active optical blind mate interconnect.
The radiation-resistant or "Space-grade" transceivers are engineered to withstand radiation doses >100 krad as per the European Cooperation for Space Standardization ECSS-Q-ST-60-15C. The qualification program of the SpaceABLE28 includes the following protocols:
- Heavy-ion test (Single Event Effect & Latch-up (SEE and SEL)).
- Cobalt 60 electron source test (MIL-STD-883G, method 1019.7) Total Ionizing Dose (TID).
- High and low energy protons test (Total Non-Ionizing Dose (TNID)).
The small, lightweight, high-bandwidth SpaceABLE28 parallel optical transceiver and SpaceCONEX28 interconnects offer extremely high aggregate data rates (over 100 Gbps, full duplex), with optical modules that are less than 1.5 cm3, weigh less than 5 g and consume less than 120 mW/lane.
