Measurement of the group-delay difference between the principal states of polarization on a low-birefringence terrestrial fiber cable.
We report some results of measurements of the frequency dependence of the state of polarization at the end of a low-birefringence long-cabled (50-km) optical fiber. The principal states of polarization and their group-delay difference were determined by making use of the Poincaré sphere representation.
