 begins by being "Our Own Guaranteed Source of Fiber." Because we manufacture one of the world’s best fibers ourselves, and have for the past couple of decades, we are our own guaranteed source of fiber . . . and yours.
Sumitomo fiber optic cables, whether loose-tube or ribbon, contain fibers manufactured by us with the fully synthetic Vapor Phase Axial Deposition (VAD) process. This process, first developed by Sumitomo Electric Industries Limited, produces optical fiber yielding outstanding geometrical and strength characteristics, with attenuation that approaches the theoretical minimum of germanium-doped silica-core glass. Excellent control of geometrical characteristics makes our optical fiber ideal for all forms of connectivity, including mechanical and mass fusion splicing.
Sumitomo cables comply with TL 9000, ISO 9001 manufacturing, and Telcordia testing (e.g., GR-20 and GR-409), RUSPE-90, and ICEA standards. The cables also undergo Sumitomo’s own aggressive environmental and mechanical testing that reaches beyond conventional industry standards.
With Sumitomo, you can rest assured that you have purchased the best constructed cables with fibers yielding the most reliable transmission in the world.
