TEC SM fiber
with heat resistant coating
Fujikura fibers have a structure suitable for fusion splicing and optical connectors based on fiber design and manufacturing technologies developed over many years.
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.
