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.
