Standard PM Fiber for DevicesStandard PM Fiber for Devices

The standard PM fiber for devices is a dedicated specialty fiber designed for various polarization-sensitive devices. It uses a mature and reliable Panda structure with symmetric, regular dual circular stress elements, offering high birefringence, excellent grindability, low transmission loss and good geometric consistency, meeting the precision fabrication and stable operation requirements of polarization-sensitive devices.

To meet diverse application needs, the series offers flexible specification options. It covers operating wavelengths of 780 nm, 980 nm, 1310 nm and 1550 nm, with a standard size of 125 μm cladding and 250 μm coating. In the core 1310 nm and 1550 nm telecom bands, it also extends to a compact 200 μm coating size and a thin 80 μm cladding / 165 μm coating size, suiting miniaturized devices and high-density array integration. These combinations flexibly adapt to various polarization-sensitive devices and PM arrays, and are widely used in AI computing infrastructure, data center interconnection (DCI), coherent optical communication backbones, quantum communication and other frontier optical communication fields, providing a reliable optical transmission medium for stable operation and technological iteration of high-end optical communication systems.
