Abstract
Systems and methods for restoring or recovering linear polarization state of an optical signal as it exits the far end of an optical fiber are disclosed. The optical signal may have an expected pattern of polarization states through a birefringent material of the optical fiber from a first node to a second node. The optical signal may be received by the second node and resulting polarization states may be measured. In certain non-limiting examples, the measured polarization states may be compared to expected polarization states to determine a characterization angle indicative of an axis of the optical fiber.
