PANDA fiber
with heat resistant coating
Fujikura PANDA fibers have a superior optical property in polarization-maintaining because of the symmetrical accuracy in cross section and the uniform constitution of stress applying parts. Based on Fujikura's fiber technology, PANDA fibers have a universal quality with not only low polarization-crosstalk and low attenuation but also the broad suitability for fusion-splice or optical connector.
Features
・The heat resistance has been improved compared with conventional acrylate coatings, and can be used in a wide temperature range of -40 ˚C to +150 ˚C.
・Product for small bending radius (R5 mm)
