SpaceABLE SM 50G and 150G radiation-resistant optical transceivers
The SpaceABLE™ SM radiation resistant transceivers are engineered to withstand radiation doses >100 krad (Si). The SpaceABLE SM embedded optical modules are rugged devices offering high bandwidth (greater than 150 Gbps) 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.
