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
