  3. 630nm band PANDA fiber


630nm band PANDA fiber

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.
