POLARIZATION-MODE DISPERSION EMULATOR

摘要

Techniques and devices for emulating polarization-mode dispersion in an optical signal that transmits through an optical fiber by using multiple birefringent wave-guiding sections (110-N) that are interconnected to have adjustable polarization-changing connectors (120). The polarization of light transmitting from one section to another adjacent section can be modified differently between different adjacent sections according to a distribution function to produce one PMD state to represent one possible PMD state of a real PMD fiber. The connectors (120) can be adjusted to produce different PMD states to represent different possible PMD states of the real PMD fiber.
