SUMITOMO ELECTRIC LIGHTWAVE INTRODUCES FUTURE FLEX® HYBRID FIBER BUNDLES Bundles offering multimode and single-mode fibers allow for even greater network capacity and scalability CHICAGO, NXTcomm – June 20, 2007 – Sumitomo Electric Lightwave, a leader in optical fiber product and developer of North America’s first air-blown fiber system for the LAN, today announced the introduction of Hybrid Fiber Bundles (HFB) to its FutureFLEX® Air-Blown Fiber® (ABF) product line. As enterprises prepare to use more video-based applications, from product demos to security surveillance, the ability to control network capacity and quickly meet bandwidth requirements in real-time is rapidly becoming essential to the success of the enterprise network. Sumitomo is meeting this market demand by expanding FutureFLEX’s fiber product line to include hybrid fiber bundles. “As enterprises ready their networks for the burgeoning demand of bandwidth-rich video and IPTV applications, Sumitomo is now offering our customers unprecedented solutions crucial to enabling enterprises in developing a ‘ready-for-anything’ network,” said Kurt Templeman, product manager, enterprise networks, Sumitomo Electric Lightwave. “End-users ensure future network expansion and immediate scalability by utilizing only a portion of the tube cells, filling the remainder as needed, effectively controlling bandwidth requirements as projects arise.” Hybrid fiber bundles can yield a three-fold increase in efficiency for each individual tube in the LAN infrastructure, as 50 and 62.5 micron multimode, single-mode, and the latest laser optimized 10 Gigabit 50/125 micron multimode fibers can now share one of FutureFLEX’s 19 tubes. Previously, either single-mode or multimode fiber bundles were blown in one or more of the inner tube cells, requiring a two-step fiber insertion. As ABF typically requires one-tenth the time and labor cost of a traditional fiber optic infrastructure, the introduction of HFB drives costs down even further. FutureFLEX’s air-blown fiber system consists of a point-to-point infrastructure of empty compact tubes, available in a variety of configurations, through which fiber bundles are blown using a pressure source of either compressed air or nitrogen. Fiber bundles can be blown through tubes at speeds of 100-to-150 feet per minute to any location within the LAN. Blowing in bundles usually takes only minutes or hours, compared with the days, weeks or months using conventional methods, allowing for quick and easy network upgrades and reconfigurations.
