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 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

Fiber Types for CWDM ApplicationsSingle Mode Fiber is required for CWDMTypes of Single Mode Fiber • Non-dispersion-shifted (NDSF), G.652, G.652.C &
G.652.D– Most common (see next slide)
• Dispersion shifted fiber, G.653– Not commonly deployed– Zero Dispersion area moved to 1550
• Non-zero dispersion-shifted fiber (NZ-DSF), G.655 – Developed to minimize issues (nonlinear effects) in
DWDM systems.

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

Section Summary • CWDM is Cost Effective
– Much less expensive than upgrading switches and routers– Maintain investments in existing equipment
• Rapid Deployments– Passive equipment that is easy to use– Plug and play installations– No disruption to existing service (Spanning Tree / SONET)
Section Summary• CWDM Multiplexers Support Dual and Single-Fiber
– Single Fiber MUXes support ½ the channels of Dual Fiber.
• Wavelength Allocation Provides Design Flexibility– Enables Passing of Legacy 1310nm and 1550nm – Complementing Bands for Expansion Ports– “Workaround” for the 1400nm Water Peak
Section Summary• MUXes and OADMs Provide Flexible Designs
– Add and Drop Linear Bus applications– Pass Band Ports enable overlaying CWDM onto existing
networks– Overlay Channels on SONET and Resilient Ring networks– Expansion Ports provide flexibility for future growth– Expansion Ports also double as 1550 Pass Band,
and enable passing channels to different locations– Both MUXes and OADMs can be used to Connect and
Bypass Nodes on ring networks
