Radiation-resistant optical transceivers

The low profile SpaceABLE® SL screw-in module (4.5 mm) mounts to the board via an LGA connector. 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 lane from −40 °C to 100°C at ultra-low bit error rates of 10-12. The optical module includes equalizers and pre-emphasis to compensate long traces; these features can be turned off for short traces (less than 10 cm) to reduce power consumption.
