Abstract

A method for screening fiber polarization mode dispersion using a polarization optical time domain reflectometer is disclosed. A pulse radiation is emitted into an end of the fiber under test, and the backscattered radiation is measured by the POTDR and used to obtain an OTDR trace. A pulse radiation is emitted into an opposite end of the fiber under test, and the backscattered radiation is measured by the POTDR and used to obtain another OTDR trace. Either one or both traces are analyzed to compare the variation of intensity of signals along the length of the fiber, the variation in signals relating to the PMD along the length of the fiber.
