  • $ 14.95 or
  • per meter

Corning 980nm 6.6/125/250µm polarization maintaining fiber with 250µm dual acrylate coating. This PM fiber is based on Panda stress applying structure which was invented and patented by Corning. Corning has a manufacturing partnership with Fujikura Ltd. Working wavelength: 980nm. Mode field diameter: 6.6+/1 µm. It has high pull strength of 200kpsi.

Corning's PANDA PM Specialty Fibers, designed with the best polarization maintaining properties in the world today, offer 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 different coating designs, Corning PANDA PM Specialty 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. In addition, PANDA PM fiber is available with High numerical Aperture, Reduced Claddings (80 µm), Low Birefringence, Erbiµm-doped and Dispersion Shifted designs as well as Polyimide and Flame Retardant Coating options.
