Small-Diameter Polarization-Maintaining Fiber for Devices

The small-diameter polarization-maintaining fiber for devices is a specialty PM fiber designed for miniaturized polarization devices and bend-sensitive polarization devices. It adopts an 80 μm cladding diameter design, offering a smaller structural size than conventional fibers, which facilitates compact device design and integration. It also provides excellent polishing performance, geometric consistency, polarization-maintaining performance, full-temperature stability, and mechanical reliability. The product is available at two operating wavelengths, 1310 nm and 1550 nm, and includes configurations with different bend resistance to meet requirements under different bending radii and device structures.
