SpaceABLE28 SL 100G (full duplex) and 300G

Radiation-resistant optical transceivers

The SpaceABLE®28 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 either a (4+4)-lane transceiver (100G full-duplex) or as separate 12-channel transmitter and 12-channel receiver modules (300G half-duplex as a pair) that operate at 28 Gbps per channel from −40°C to 85°C at ultra-low bit error rates of 10-9.

 

Features & Benefits

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..
