Polarization Maintaining Fibers
High Performance Polarization Maintaining Fibers (400 - 2000nm)
PANDA PM Fiber design uses two stress applying parts to create an extremely high birefringence, resulting in fiber with excellent polarization maintaining properties. This design was invented and patented by Corning Incorporated in cooperation with Fujikara Ltd.
Our range of PM Fibers are designed with the best polarization maintaining properties including low attenuation and excellent birefringence for high performance applications. Available in a wide range of standard operating wavelengths up to 1550 nm, and with a variety of coating designs, PANDA PM Special Fibers are optimal for high performance polarization retaining fiber applications. This field-proven fiber supports high growth applications and performs well over a wide temperature range.
