Optical Networking using Ns2 simulation | Ns2 Projects

Optical fibers are essentially very thin glass cylinders or filaments which carry
signals in the form of light
DWDM - Dense Wavelength-division multiplexing
DWDM Provides enormous bandwidths at much lower cost
The Rate at which the laser is turned on and off is the rate of communication.it is called the bit rate.
Decrease The Bandwidth cost
a number of optical signals at different carrier wavelengths may be simultaneously carried by the same fiber.
Low signal attenuation ,Low signal distortion ,Low power requirement ,Low material usage , Small space requirements ,Low cost.
