The objective of this presentation is to show how important and critical optical interconnect is becoming in the development of high-performance embedded systems.

Embedded Systems To Reach $133B by 2020*

Eyes and ears everywhere

Command, Control, Compute, Communicate, Intelligence, Surveillance, Reconnaissance

ISR Process

ISR embedded systems provides unparalleled advantage

  • Intelligent: learning machines
  • Data rich: real-time and historical data
  • Secure: hack-resistant communications
  • Reliable: no single point failure
  • Small: more payload for other systems
  • Scalable: simple upgrades, long life
  • Multipurpose: target ID, weather, communications.
Computerized Command, Control, Communications, Intelligence, Surveillance

Embedded Optics Benefits

Performance

  • Scalable BW – up to 28G
  • Low bit error rate: 10-15
  • Low loss – 0.003 dB/m (OM3 @10G)
  • Reach – 300 m (OM3 @10G)
480G full duplex I/O card

SWaP-C

  • Chip size optical transceivers
  • Small light weight glass fiber
  • High I/O density – 48 fibers in MT connector
  • Lower power – 100 mW/10Gbps  
Optic fiber offer much better I/O density that copper interconnect.

Rugged

  • -40 ºC to 85 ºC operation @ 10 Gbps
  • MIL-STD-810xx Shock and vibration
  • Moisture resistant
  • EMI and EMP immune
Optic fiber are immune to electro magnetic interferences.
