SpaceABLE 28G SL Series 4TRX, 12TX, and 12RX

SpaceABLE 28G SL Series high-speed radiation-resistant optical transceivers

The SpaceABLE® 28G SL Series radiation-resistant onboard embedded optical transmitter and receiver modules offer radiation hardness, robustness, longevity, and high I/O density. The SpaceABLE line of products with their intrinsic radiation resistance, are well suited to provide optical interconnect within space vehicles. These devices are extremely rugged and deliver bandwidth in excess of 300 Gbps in a chip size part.

The SpaceABLE 28G SL Series radiation resistant transceivers are engineered to withstand radiation doses >100 krad (Si). The SpaceABLE 28G SL Series low profile screw-in module mounts to the board via an LGA connector (interposer). 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 up to 28 Gbps per channel over a recommended operating temperature range of –40 ºC to 85 ºC at ultra-low bit error rates of 10-9.
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.
