Panda Polarization Maintaining Fiber (PMF)

Panda Polarization Maintaining Fiber (PMF) is a high-performance specialty optical fiber designed to preserve the polarization state of transmitted light over long distances and under varying environmental conditions. Featuring a classic Panda stress rod structure, this fiber provides high birefringence, low insertion loss, and superior polarization stability, making it ideal for precision optical applications.

Panda PM fiber is widely used in fiber optic gyroscopes (FOG), interferometric sensors, coherent optical communication systems, and fiber laser assemblies where stable polarization control is critical. With excellent environmental stability and consistent optical performance, Panda Polarization Maintaining Fiber is a preferred choice for advanced photonic systems.
