(PR NEWSWIRE) Bell Labs Sets World Record With 10-Gigabit Serial Transmiss Bell Labs Sets World Record With 10-Gigabit Serial Transmission Over 1.6 Kilometers Of Lucent's New LazrSPEED(TM) Multimode Fiber HOLMDEL, N.J., Oct. 11 /PRNewswire/ -- Scientists from Bell Labs, the research and development arm of Lucent Technologies (NYSE: LU), have set a new world's record for multimode fiber transmission, sending 10 gigabits (billion bits) of data per second over 1.6 kilometers of Lucent's new LazrSPEED multimode fiber for local area networks (LANs). "They said it couldn't be done," said Janice Haber, vice president of Systems Engineering and Offer Development in Lucent's Network Products Group. "Bell Labs' breaking the 'kilometer distance barrier' demonstrates the robustness of our recently introduced LazrSPEED fiber at very high data rates, and it's a great example of Lucent's speed to market." Last May, in a system using worst-case field conditions, the team demonstrated 10-gigabit serial transmission over 300 meters of prototype multimode fiber that was later introduced as LazrSPEED. To simulate rigorous real-world conditions, their demonstration was done with four worst-case optical connections, plus worst-case cabling stress effects and alignment tolerances of low-cost transceiver packaging. "We're bringing the religion of reliability to local area networks," said Martin Nuss, head of Bell Labs Optical Enterprise Networks Research, noting that the performance level for both the 300-meter and 1.6-kilometer distances showed an error rate of less than one in one trillion. Before the Bell Labs 10-gigabit/300-meter transmission demonstration in May, transmission over much less than 300 meters was considered to be the maximum capacity for practical multimode systems. Both demonstrations used an 850nm vertical cavity surface emitting laser (VCSEL) transmitter, which has been projected to offer the lowest total system cost while retaining cost effective backwards compatibility to lower speed legacy applications. "In our 300-meter demonstration we established the specifications for a robust, practical 10-gigabit system for in-building networks with guaranteed performance levels in real-world conditions. Now, the 1.6-kilometer link has demonstrated what might be the ultimate capability of LazrSPEED fiber," said Nuss. Lucent introduced the LazrSPEED offer, an end-to-end 10-gigabit structured connectivity solution, in August and expects to begin accepting orders in January. Lucent Technologies, headquartered in Murray Hill, N.J., designs, builds, and delivers a wide range of public and private networks, communications systems and software, data networking systems, business telephone systems, and microelectronics components. Bell Labs is the research and development arm for the company. For more information on Lucent Technologies, visit its Web site at lucent.com .
