SpaceABLE28 SL 100G (full duplex) radiation-resistant optical transceivers
The SpaceABLE28™ SL radiation resistant transceivers are engineered to withstand radiation doses >100 krad (Si). The SpaceABLE28 SL low profile screw-in module (4.5 mm) mounts to the board via an LGA connector. It is offered as a (4+4)-lane transceiver that operates at 28 Gbps per lane from −40 °C to 85 °C at ultra-low bit error rates of 10-12.
Furthermore, all our devices are tested following ECSS process and lot acceptance. Component pre-screening can be done for every batch of transceivers sold for this application.
