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.

Features & Benefits

  • 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
  • Standard MT parallel fiber connector
  • RoHS
  • Equalizer, pre-emphasis, adjustable output
  • Monitoring: LOS, RSSI, temperature, etc.
  • Attaches to system board with 1.55 mm LGA interposer

Applications

    Optical Interconnect Design Challenges in Space

    Aeronautical applications face many design challenges that are unique to their intended environment. The best practices for optical interconnect design for space applications include the use of radiation-resistant technology to defend against space radiation, the use of components and devices that are designed to operate in harsh environments, and meeting size, weight, and power (SWaP) and long-term reliability requirements. Finally, it is recommended to follow open standards like VPX and to look for solutions that comply with MIL and quality standards.
