Lucent s Leading-Edge System Uses a Previously Untapped Optical Wavelength Range to Build Cost-Effective, Higher-Capacity Networks
Tokyo, Japan. Lucent Technologies (NYSE: LU) today announced the installation and deployment of a leading-edge optical networking system that will enable NTT Communications of Japan to dramatically increase its network capacity by transmitting information through a wavelength range in its fiber that it could not previously use.
NTT Communications has deployed the Lucent Technologies WaveStar™ OLS 400GL, which uses dense wave division multiplexing (DWDM) technology and a new L-Band optical amplifier to significantly expand the capacity of its long-distance network.
"The L-Band amplifier will go a long way toward not only increasing capacity, but also increasing the number of fiber types across which DWDM can transmit information," said Barry Weinbaum, general manager, optical long-haul solutions, Lucent Technologies. "NTT Communications was among the first to recognize the importance of this technology, and we are honored that NTT Communications entrusted Lucent with bringing this innovative technology to its network."
DWDM technology provides increased capacity by simultaneously transmitting multiple wavelengths -- or colors -- of light across a single fiber strand, with each color carrying a distinct stream of information. While most of today s fiber-optic communications travel through a specific range of wavelengths called the C-Band, the WaveStar OLS 400GL, incorporating the L-Band amplifier, enables service providers to transmit data, voice and video traffic in the L-Band optical wavelength range as well. By opening up this previously untapped wavelength band, this new amplifier allows NTT Communications to dramatically increase the number of wavelengths it sends through its fiber.
The L-Band system being deployed by NTT Communications is specifically designed by Bell Labs to maximize the bandwidth potential of NTT Communications dispersion-shifted fiber. Due to its physical characteristics, dispersion-shifted fiber can carry many more wavelengths in the L-Band than it can in the C-Band.
The Lucent L-Band amplifier will allow the carrier to simultaneously transmit up to 40 10-gigabit-per-second (Gb/s) wavelengths in the L-Band. Therefore, the Lucent system will provide a nearly 16,000 percent increase in network capacity -- enough to simultaneously transmit the data contained on more than 80 CD ROMs each second. This is Lucent s first commercial deployment of a C+L band system.
About NTT Communications
NTT Communications is one of the largest operators, established in July 1999 after NTT (Nippon Telegraph and Telephone Corporation) s re-organization. It provides domestic long-distance communications services, international telecommunications services, and IP network services.
About Lucent Technologies
Lucent s Bell Labs has garnered more than 2,500 patents in optical technology alone. Lucent was first to market with a DWDM system in 1995, and has since shipped more DWDM systems than any other vendor. Lucent also was first to market with an all-optical switch -- delivering the industry s first all-optical switch to a customer in July 2000.
