Standard Panda Polarization-Maintaining Fiber For Optical Devices
Fiberlink’s standard polarization-maintaining (PM) fiber adopts classic Panda-type structure with symmetric dual circular stress rods, where the fiber core and two stress rods are aligned on a straight line. It delivers superior birefringence, outstanding polishability, low attenuation and highly consistent geometric dimensions.
Description
Product Overview
Fiberlink's standard polarization-maintaining (PM) fiber adopts classic Panda-type structure with symmetric dual circular stress rods, where the fiber core and two stress rods are aligned on a straight line. It delivers superior birefringence, outstanding polishability, low attenuation and highly consistent geometric dimensions.
Manufactured with tight dimensional tolerances and fully compliant with RoHS & REACH standards, this series covers 780nm, 980nm, 1310nm and 1550nm mainstream communication wavelengths, widely used as pigtail fiber for fiber optic gyroscopes, lasers and general polarization-sensitive optical devices.
Fiberlink's standard PM device fiber serves core infrastructure applications including coherent optical communication backbone, quantum communication, data center interconnect (DCI) and CPO co-packaged optics.
Key Features
