SDN Always Growing With Fiber's Future

One bundle of fiber cable (not much thicker than a pencil) can carry ALL of the world’s current communications traffic. But because of exploding business data and research needs, multiple simultaneous HD channels and possibly 3D “holographic” HDTV and games on the market, there is a need for more. Much more. How much bandwidth is enough? Think 20 to 30 Gigibits per second to homes and businesses in a decade. Obsolete copper technology can’t do even 1/1000th of that bandwidth, and then not for more than a few hundred yards. SDN Communications is seeing the trend. Equipping an existing fiber network with newer electronics and with lasers that pulse light faster (or lasers using different wavelengths of light) can vastly increase the available bandwidth without changing the fiber itself. That’s why fiber networks, like SDN’s, are said to be “future proof.” What does the future hold? A standard-definition TV signal requires a bandwidth of about 2 Mbps — two million bits (zeros and ones) per second. HDTV requires as much as 8 Mbps. New compression technology, such as MPEG4, 3D-immersive HDTV (a technology already being used in some academic and industrial settings) will require 100 to 300 Mbps. This comparison may help show how 1Gbps could look small a decade from now. We have absolutely no reason to think that innovation will stop. Neither will the need for more bandwidth. That’s why SDN is ready for the future. We’ve already built the Research Education and Economic Development (REED) Network across our eight-state network. How powerful is SDN’s REED Network?

  • It can offer bandwidth of 50,000 Mpbs to universities and research institutions.
  • It’s so fast, it can download the entire text of the U.S. Library of Congress in 12 minutes.

Bandwidth needs are always increasing. SDN Communications embraces the opportunity to expand its reach beyond the hundreds of businesses and communities we already serve, delivering the best and most reliable network in the region.
