1 Introducing the FTB-5800
Chromatic Dispersion
Analyzer
In today’s advanced optical network, chromatic dispersion management
has become an important issue. Present-day networks must deal with high
data rates, high channel counts and long distances between
optical-electrical-optical regenerators.
Main Features
The FTB-5800 Chromatic Dispersion Analyzer is a reliable solution to
chromatic dispersion management. It uses the phase-shift measurement
method to measure phase variations at fixed frequencies and combines
them relative group delays.
Fitting equations are then applied to the computed data to calculate
chromatic dispersion. This method allows for more accurate and precise
results in the C and L bands.
