SpaceABLE SL 50G (full duplex) and 150G 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-lane transmitter, or a 12-lane receiver. All modules operate at 12.5 Gbps per lane from −40 °C to 100 °C at ultra-low bit error rates of 10-15. 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.
