Optical Fiber

Advancing Your Network at the Speed of Light  — with the Pioneer and Industry Leader
in Optical Fiber Manufacturing

All optical fiber is not created equal. That statement is more true today than ever as the network evolves with increasing high-speed, high-bandwidth, quadruple play (voice, video, data, and wireless) services that require the highest quality and most reliable optical transmission properties, signal integrity for optimum latency, and fail-proof performance.

The advancements in communications that we witness today are largely attributed to Sumitomo Electric’s invention in the 1970s of the patented Vapor Phase Axial Deposition (VAD) manufacturing process — yielding superior optical geometrical strength characteristics and attenuation that approaches the theoretical minimum of germanium doped silica core glass for the most reliable optical fiber transmission and connectivity properties in the industry.

Sumitomo also developed the world’s lowest attenuation Z-fiber with a record of 0.154dB/km and pioneered the industry’s first bend insensitive fiber (BIF), PureAccess®. PureAccess fiber is the world’s best selling brand of BIF with over 6 million km deployed.

With our superior quality zero water peak single-mode and non-zero dispersion shifted fibers — PureBand®, PureMetro®, PureGuide® and PureAccess® and other optical fiber types — you’ll be deploying the industry’s best optical fiber whether for Long Haul, Metro, Access, or Undersea.

Committed to continuous innovation to keep our customers at the forefront of leading edge technology, Sumitomo continues to introduce new fiber types for the ongoing advancement of communications and information networks.
