OPLL vision...

  • Coherent WDM systems:
    • INCREASED BANDWIDTH BY > 10 X
    • LOWER COST PER BIT
    • Closely spaced, long haul WDM systems
      • 2.5 Gbps per l
      • 5-10 GHz spacing
      • 4000 km
    • HIGH OPTICAL BANDWIDTH EFFICIENCY
    • TRANSPARENT OPTICAL NETWORK
opll competitive advantage
OPLL Competitive Advantage
  • OPLL narrow linewidth laser
    • patented and proven DFB laser technology
    • narrows spectrum from > 10 MHz to < 10 kHz
    • reduces phase noise by > 1000 X
  • Low intensity noise laser for today
    • increased signal to noise ratio
    • improved receiver sensitivity
    • reduced fiber network cost
  • Stable, low phase noise laser for tomorrow
    • required for coherent applications
    • current solutions are expensive, fragile and unstable

what is coherent communications
What Is Coherent Communications?
  • Direct detection systems
    • currently deployed
    • sensitive only to INTENSITY of light
    • detects whether the light is ‘on’ or ‘off’
  • Coherent systems
    • sensitive to PHASE of light
    • received light mixed with local laser oscillator
    • optical gain at the receiver
  • Analogous to AM versus FM radio
    • substantial technology advancement
    • increased transmission distances
    • significantly improved signal quality
why coherent
Why Coherent?
  • Improved receiver sensitivity
    • “Up to 20 dB”1 improvement over direct detection
    • “Up to an additional 100 km”1 in transmission distance at same power

(1) Govind Agrawal - Fiber Optic Communications.

  • Efficient use of fiber
    • l spacing of 5-10 GHz are required to get
    • 10 X MORE DATA within existing dispersion limits
  • High flexibility transparent optical network
  • REDUCED COST PER TRANSMITTED BIT!
