This book demonstrates the implementation of an automated measuring
system for very efficient measurement of chromatic dispersion, which
uses a modulation phase shift method over long haul of optical single
mode fiber. The authors show how a new scheme for measuring chromatic
dispersion is adopted in conjunction with a tunable laser (TLS),
providing the optical power at required wavelength and digital
oscilloscope (DOSC) for measuring the phase difference between microwave
signals from transmitter and microwave signals at the receiver. This is
a novel approach for real-time chromatic dispersion in optical systems
such as optical fibers. The setup used is very simple, accurate and cost
effective, compared to other methods such as direct measurement,
differential mode delay, polarization mode dispersion measurement and
phase delay method.
