SpaceABLE 10G SL Series radiation-resistant optical transceivers
The SpaceABLE® 10G 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 120 Gbps in a chip size part.
The SpaceABLE 10G SL Series radiation resistant transceivers are engineered to withstand radiation doses >100 krad (Si). The low profile SpaceABLE 10G SL Series screw-in module mounts to the board via an LGA connector (interposer). It is offered as a (4+4)-lane transceiver, a 12-channel transmitter, or a 12-channel receiver. All modules operate at 10.3125 Gbps per channel over a recommended operating temperature range of –40 ºC to 85 ºC at ultra-low bit error rates of 10-12.
