Polarization scrambling using a short piece of high-birefringence optical fiber and a multifrequency laser diode

Describes a technique for avoiding system performance degradation and outages in an optical fiber system due to state of polarization mismatch between signal and polarization-sensitive system components. The technique uses a short piece of high-birefringence fiber and a multifrequency laser to create a depolarized source that can be used to transmit data without fading.<
