JDS Uniphase's Dynamic Gain Equalizer extends system reach reduces cost for 10 and 40 GB/s optical systems

摘要

The key feature of the DGE is that it simultaneously provides a smooth optical attenuation profile of wavelengths (low wavelength resolution) and compensates for local spectral features (high wavelength resolution). This feature differentiates the DGE from similar products that are not as effective at modifying the attenuation of one part of the spectrum without compromising the other portions of the profile. The wavelength resolution of the DGE is 2.6 nanometers.
