    Are Stretching the Capacity of Fiber Infrastructure

  • Expanding Capacity of Fiber NetworksThree Options1) Install New Fiber

    New links for each location/application/data type Expensive and time consuming installation

    2) Protocol Converters / Aggregation Circuit Emulation converges the different applications

    into TDM or Ethernet Expensive and complicated equipment

    3) Wavelength Division Multiplexing

  • WDM OverviewWavelength Division Multiplexing Overlaying multiple wavelengths on one fiber link

    Each wavelength is a secure and an independent data channel Each channel is protocol and speed transparent (up to 10 Gig) Increases the capacity of the fiber infrastructure

    Inexpensive when compared to alternatives Installing new fiber (costly and time consuming) Circuit Emulation (costly and complex training and support)

    Implementation has no impact to existing network Legacy 1310nm or 1550nm network treated as additional

    CWDM channel

  • WDM Single Fiber

    Single-Fiber utilizes Bi-Directional (BIDI) WDM technology

  • WDM Overview

    WDM technology enables a fiber optic cable to carry multiple Wavelengths (Lambdas)

    Each Wavelength is an independent data Channel that can transport any network protocol or data rate

    Additional Channels can be added if the Wavelengths are unique

    Dual Fiber Links

  • DWDM and CWDMDense Wavelength Division Multiplexing

    Coarse Wavelength Division Multiplexing

  • CDWM and Standard Wavelengths

    Standard 1310nm or 1550nm have wider tolerances and utilize more of the spectrum than CWDM wavelengths

    Standard wavelengths can be used in conjunction with the CWDM wavelengths (through Pass Band ports)

    Standard wavelengths are not precise enough for the 20nm filters used in CWDM multiplexers

    Standard wavelengths can be converted to CWDM wavelengths with Transponders or SFPs

    Standard 1310

    Standard 1550

  • CDWM Wavelength Band AllocationDifferent Bands or groupings of wavelengths ITU Bands 5 bands defined by ITU Lower Band = lower 10 wavelengths

    Legacy 1310 is a subset of Lower Band (1270nm to 1360nm.)

    Upper Band = upper 8 wavelengths Upper 1 (1510, 1530, 1550, 1570) commonly used for CWDM MUXes Upper 2 (1470, 1490, 1590, 1610) compliments Upper 1

    G.652.D Most common (see next slide)

    Dispersion shifted fiber, G.653 Not commonly deployed Zero Dispersion area moved to 1550

  • Fiber Types for CWDM Applications

    1) Know the type of fiber installed in your network Contact the manufacturer Test your fiber links

    2) Plan accordingly Determine the areas of the spectrum that have the

    highest attenuation in the fiber link Use the optimum attenuation areas of the CWDM

    spectrum in your design
