SpaceABLE 10G SM 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). These modules are 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.

Features & Benefits

  • Small: Less than 6  mm high (SMT version)
  • 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: 85 mW/channel (<10 pJ per bit)
  • 4 TRX (4+4)-lane per device (40G, full duplex)
  • 12 TX or 12 RX channel per device (120G)
  • Multimode 850 nm wavelength laser
  • Standard MT parallel fiber connector
  • Surface mountable or pluggable
  • RoHS or tin-lead
  • Monitoring: LOS, RSSI, temperature, etc

Applications
