SpaceABLE 10G SL Series 4TRX, 12TX, and 12RX

Radiation-resistant optical transceivers

The SpaceABLE^® 10G SM 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.

Small: Less than 6 mm high (module and interposer)
Rugged: withstand radiation doses >100 krad (Si) and qualified per MIL-STD 883 shock and vibration
Expected life: up to 20 years
Performance: up to 10.3125 Gbps/channel over a recommended operating temperature range of –40 ºC to 85 ºC
Sensitivity: –9 dBm for BER 10^–12
Low power consumption: 115 mW/lane (<10 pJ per bit)
4 TRX (4+4)-lane per device (40G, full duplex)
12 TX or 12 RX channel per device (120G, half duplex)
Multimode 850 nm wavelength laser
Over 100 m reach on OM3 ribbon fiber
