Sumitomo Electric Opens a Special Web Page for ITU-T G.654.E Terrestrial Ultra-low Loss Optical Fibers and Cables, “PureAdvance™” Series

Sumitomo Electric Industries, Ltd. has established and opened a special web page for ITU-T G.654.E terrestrial ultra-low loss optical fibers and cables, PureAdvance™ series, on its website that introduces broadband solutions. （https://global-sei.com/fttx/）

 

 

 

PureAdvance™, compliant with the international standard ITU-T G.654.E, is an optical fiber that realizes low transmission loss by using pure silica for the core part, through which optical signals propagate in the optical fiber. Sumitomo Electric has been developing and mass-producing pure silica core low loss optical fibers for more than 30 years and has achieved a world record for low transmission loss of 0.1419 dB/km in its development, followed by success in mass production of ultra-low loss optical fibers of 0.144 dB/km.

 

 

 

With the introduction of 5G services, the increasing use of various internet contents, and the spread of working remotely, the demand for info-communication traffic continues to increase around the world. For this reason, the needs for high-performance optical fibers capable of transmitting large-capacity optical signals over a long distance efficiently has been increasing. Sumitomo Electric will continue to develop high-performance optical fibers and cables, and provide products that meet the demands of society.
