DWDM is a Fiber Optic Transmissiontechnique that employs light wavelengthsto transmit data Parallel-by-bit or Serial by
Character.
Increased service Needs
Fiber exhaust
Layered bandwidth management
Laying more fiber
Time Division Multiplexing (TDM)
Dense wavelength Division Multiplexing (DWDM)
Economic solution where cost of fiber laying is minimal
May not be able to provide new services or utilize bandwidth management capability of a unifying optical layer.
