Spectral Bands and Grids

“Grids” are used for location of nominal central frequencies in WDM fiber systems. The grid is divided into bands.

Channel Spacing in DWDM, CWDM and WWDM Fiber-Optic Systems

Capacity of WDM Systems

The ultimate capacity of a WDM system depends on how closely optical channels can be packed in the wavelength domain.

Number of Channels in DWDM and CWDM Systems

Number of WDM Channels

In a given spectral band, the number of channels in a WDM system depends on the particular channel spacing of the grid.

Unidirectional & Bidirectional WDM

Unidirectional only allow transmission in one direction, while bidirectional allow transmission in two opposite directions.
