Fixed Grid & Flexible Grid

The traditional 40- or 80-wavelength DWDM system uses the fixed grid (fixed spectrum) mode, which features a fixed center frequency and fixed channel spacing of 50 GHz or 100 GHz.

Modulators & Fixed Frequency Shifters

Acousto-optic modulators are used to vary and control laser beam intensity. They can also be used as fixed frequency shifters due to fact that the diffracted order is frequency shifted by the amount of the

Fiber-coupled AOM (Acousto-Optic Modulator)

These fiber AOM''s are also used as a fixed frequency shifter. They have the ability to slightly shift positively or negatively the central optical wavelength by a fixed value equal to the RF frequency
