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
