Presentation Transcript

  1. 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

  2. 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

  3. Narrow Spectral Linewidth before OPLL linewidth measured with Er laser 3+

  4. Narrow Spectral Linewidth with OPLL linewidth measured with Er laser 3+

  5. Short Term Frequency Stability before OPLL phase noise measured at Dt = 150ms

  6. Short Term Frequency Stability with OPLL phase noise measured at Dt = 150ms

  7. How it is done OPLL Block Diagram

  8. 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

  9. 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!

  13. Roadmap To Coherent 2000 Narrow linewidth, direct modulation laser (prototype) 2001 Fiber RIN Model (Phase I) Long term stable, external modulation laser • 2.5 Gbps, sub-kHz linewidth Optical frequency standards • Sub-kHz accuracy, 10 GHz resolution 2002 Fiber RIN Model (Phase II) Heterodyne receiver • DBR laser, 2 THz tunability, 10 GHz resolution 2003 Coherent WDM • 128 – 256 ls, 10 GHz spacing

  14. Roadmap To Market Entry 2001 Direct modulation laser transmitter • targeting metropolitan networks • simultaneously supports on each laser • Gigabit Ethernet • SONET (OC-48) • Fibre channel 2002 External modulation laser transmitter • targeting long haul networks 2003 Coherent WDM

  15. Opportunities Along The Way • Narrow linewidth laser transmitters provide • improved dispersion performance • low intensity noise (high SNR) • low bit error rate • Market opportunities to be exploited • low cost metropolitan networks • high performance long haul networks • wide bandwidth WDM

  16. Direct Modulation Transmitter • Existing prototypes • Lowest cost solution for metropolitan networks • Improved QAM transmissions over short to moderate links • up to 70 km proven (without amplifiers) • up to 400 km possible (with amplifiers)
