Polarization-maintaining fiber optic patch cords (tail fibers) are a type of fiber optic connector featuring standard fiber optic connectors at one or both ends. They are manufactured using polarization-maintaining fiber and precise stress axis alignment to create fiber optic patch cords (tail fibers). The polarization-maintaining fiber optic patch cords produced by our company utilize imported polarization-maintaining fiber optic connectors, offering low loss, high extinction ratio, and return loss. We can also provide AR coating on the fiber end face according to customer requirements, which is used to optimize fiber-to-free-space coupling.

Main Features
Ultraviolet wavelength polarization-maintaining fiber connectors (visible light polarization-maintaining fiber connectors) support multiple communication wavelengths, including 460 nm, 488 nm, 532 nm, 590 nm, 632 nm, 638 nm, 650 nm, and 680 nm.
The connectors use imported connector components, featuring low loss and high extinction ratio.
They offer fast-axis, slow-axis, and custom-angled alignment options to meet diverse customer requirements.
The connectors are available in various models, including FC, SC, and LC, and support custom polarization-maintaining ends (steel-jacketed pins).
Fiber end faces can be provided with PC, UPC, APC, or custom-ground angles.
