4 The Only Constant is Change Enterprises Service Providers Utilities & Energy Government Education

5 The Challenge Convergence, New Applications and Services, and Migration to the Next Generation Network Video Data Center Connectivity High Definition TV Internet Video IP Security & Traffic Video Distance Learning Wireless Backhaul 3G and 4G Services SaaS Cloud Computing Remote Backup Carrier Ethernet Ethernet Business Services Migration from Legacy Protocols Are Stretching the Capacity of Fiber Infrastructure

6 Expanding Capacity of Fiber Networks Three Options 1) 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

7 Recession-Proof Consulting Services with CWDM Network Design Introduction WDM Technology Overview CWDM and Fiber Cabling Multiplexing Equipment Application Examples Wavelength Conversion

8 WDM Overview Wavelength 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

9 WDM Single Fiber Dual Fiber utilizes one wavelength over two strands of fiber Rx 1310nm Tx Tx 1310nm Rx Single-Fiber utilizes Bi-Directional (BIDI) WDM technology Tx / Rx 1310nm 1550nm Two independent wavelengths over one strand of fiber Rx / Tx

10 WDM Overview Dual Fiber Links 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

11 DWDM and CWDM Dense Wavelength Division Multiplexing Coarse Wavelength Division Multiplexing

12 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

13 CDWM Wavelength Band Allocation Different 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 Lower 10 Upper 8 Upper 2 Upper 1 Upper 2 O Band E Band S Band C Band L Band ITU Bands

15 Fiber Types for CWDM Applications Single Mode Fiber is required for CWDM Types 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.

16 Fiber Types Optimized for CWDM Non-dispersion-shifted fiber (NDSF) 1.0 Water Peak Loss (db/km) G.652 G.652C G.652D nm

17 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
