Abstract
In an optical communication system using polarization scrambling of the transmitted optical signal, the scrambling causes the polarization vector to rotate. The scrambler includes a modulator to modulate either the phase or the wavelength of the optical signal. A polarization dispersion device converts the phase modulation or wavelength modulation into polarization modulation. This polarization dispersion device consists of the optical communication fibers on the output side of the modulator.
