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 optic connectors, offering low loss, high extinction ratio, and low return loss. We also provide optical fiber end-face AR coating upon customer request to optimize fiber-to-free-space coupling.
