SpaceABLE28 SL 100G

SpaceABLE28 SL radiation resistant optical transceivers

SpaceABLE28 SL 100G radiation-resistant optical transceivers

The SpaceABLE28SL radiation resistant transceivers are engineered to withstand radiation doses >100 krad (Si). The SpaceABLE28 SL embedded optical modules are rugged devices offering high bandwidth (greater than 100 Gbps, full duplex) in a chip-size package.
Furthermore, all our devices are tested following ECSS process and lot acceptance testing, and component pre-screening is done for every batch of transceivers sold for this application
