TEC PANDA fiber
with heat resistant coating
Fujikura's TEC PANDA fibers with heat resistant coating can operate in a wide range of temperature between -40 ℃ and +150 ℃. The fibers have a superior optical property and universal quality with not only low polarization-crosstalk and low attenuation but also the suitability for fusion-splice or optical connector. Thermally-diffused Expanded Core (TEC) technology expand the mode field diameter by the heat generated during fusion bonding.
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.
・Thermally-diffused Expanded Core technology is applied to increase the mode field diameter by the heat generated during fusion bonding.
・Suitable for bonding with silicon photonics devices.
