Polarization-maintaining fiber patch cords (tail fibers) are fiber optic connectors featuring standard fiber optic connectors at one or both ends. They are manufactured using polarization-maintaining fibers with precise stress-axis alignment to create fiber patch cords (tail fibers). Our polarization-maintaining fiber patch cords utilize imported polarization-maintaining fiber connectors, offering low loss, high extinction ratio, and low return loss. Optional AR coating on fiber end-faces is available upon request to optimize fiber-to-free-space coupling.
