A History of Innovation
The corporate culture of OFS today is rooted in the historic achievements of AT&T, Bell Labs and Lucent Technologies. For 12 decades, brilliant inventors and engineers from these companies poured their creativity and ingenuity into the OFS legacy.
The history of OFS Labs dates back to the earliest days of optical fiber communication and, through its corporate heritage, to the invention of the telephone by Alexander Graham Bell. Starting with the development of MCVD (modified chemical vapor deposition), the entire technology for preform fabrication, fiber draw and fiber design and characterization was developed within the Bell Labs research group and moved into manufacturing in Norcross, Georgia, U.S.A. The origins of optical fiber manufacture - and the very foundation of OFS - can be traced directly back to the group.
Today, OFS Labs is staffed with many former Bell Labs scientists and engineers. The current staff participated directly in many of the exceptional innovations mentioned below - and some served under mentors who pioneered optical fibers decades ago.
When Furukawa acquired OFS from Lucent Technologies, scientists brought more than their Bell Labs legacy to OFS Labs. They also transferred a substantial base of intellectual property running the full gamut of optical technologies. We continue to build on that asset and now hold more than 600 key domestic and foreign patents. Many of these patents have had a substantial impact on the global application of optical technologies.

The story begins in 1880
After inventing the telephone, Alexander Graham Bell built what he considered his greatest invention - the photophone. Patented in 1889, the world's first optical transmission system could carry voices over short distances using sunlight and a crude assortment of mirrors and electric gadgetry.
However, the corporation Bell co-founded - the Bell Telephone Company - remained focused on commercializing the telephone. Although Albert Einstein foresaw laser technology in 1917, the field of optical communications languished for decades.
How can light turn corners?
During the 1950s, scientists around the globe were closing in on the mysteries of lightwave communications - a technology with a stunning array of applications still emerging today. Two problems bedeviled them: How to get lightwaves to travel around corners, and how to create a reliable transmission path immune to adverse weather conditions.
At Bell Labs, engineers knew that transparent rods of glass or plastic could be stretched into long, flexible optical fibers. These "waveguides" could solve the weather interference and line-of-sight problems. The real challenge, though, was to design a waveguide system that could carry lightwaves as economically as copper transmits electrons.
A leap forward to lasers
A major breakthrough occurred in 1958, when two researchers associated with Bell Labs published a paper on the principles of amplifying light. Even before their patent was issued in 1960, the paper triggered a gold rush of innovations related to the laser, the first light source powerful enough to transmit information. Looking back at that era, Scientific American noted, "Patent piled on patent [as] Bell Labs and others churned out a stream of innovations that continues unabated today."
Introducing optical fiber to the marketplace
AT&T, Bell Labs and Lucent didn't stop at the patent office - they pioneered the application of optical fiber technology to real-world situations. A few examples of these milestones:
1977: Field testing of the first commercial use of optical fiber in a Chicago telephone system
1980: Construction of “the Northeast Corridor,” a Bell-designed lightwave route from Boston to Washington, D.C.
1987: Manufacture of fiber for the first trans-Atlantic optical fiber cable
1988: Manufacture of fiber for the first trans-Pacific optical fiber cable
1999: Demonstration of ultra-dense WDM transmission of 1,022 channels on a single fiber
OFS takes the helm
Following in the steps of our corporate predecessors, OFS and OFS Labs will continue to shape the future of optical communications and optical fiber technology. We don't know what the next 120 years will bring, but we know this: We'll still be making waves.
