Lucent Technologies Delivers Record-Breaking Optical Networking Capacity; Five Times Greater Than Current Systems AT&T is First Customer to Deploy MURRAY HILL, N.J., Jan. 26 /PRNewswire/ -- Lucent Technologies (NYSE: LU - news) unveiled a global optical networking system that delivers five times the bandwidth of today's commercial fiber-optic systems. Lucent's system provides up to 400 gigabit-per-second capacity over a single strand of fiber -- equivalent to carrying the per-second traffic of the entire worldwide Internet over one fiber. AT&T will be the first to test and deploy the new system. Designed by Bell Labs, Lucent's single-platform system, called the WaveStar(TM) OLS 400G, is the first to enable communications providers to grow incrementally from one to 80 wavelengths, or channels. Leapfrogging current competitive offerings, Lucent's new optical networking system can be configured to handle up to eight fibers, each transmitting 400 gigabits per second, to give communications providers a maximum capacity of 3.2 terabits (or 3.2 trillion bits) per second of voice, video and data traffic. That's equivalent to transmitting over 90,000 volumes of an encyclopedia in one second. At this triple-terabit rate, communications service providers can realize equipment cost savings up to 40 percent over lower-capacity systems available today from other vendors. Lucent's WaveStar system is also the first to support a simultaneous mix of multi-gigabit speed rates of 2.5 Gb/s and 10 Gb/s over one fiber, and it's the first to support equipment from a variety of vendors transmitting at a mix of these two rates. These capabilities enable carriers to ''pay as they grow,'' adding capacity as needed while leveraging their existing infrastructure. ''Lucent is driving down the ongoing cost of transmitting a bit of information close to zero while pushing capacity towards infinity,'' said Gerald Butters, president of Lucent's Optical Networking business. ''With other commercial systems offering today a maximum of 80 gigabit-per-second capacity over one fiber, Lucent's 400 gigabit-per-second system takes optical networking to a new level. With this five-fold increase in capacity over a single fiber, we've in essence taken Dense Wavelength Division Multiplexing - DWDM - and created 'Ultra-Dense' Wavelength Division Multiplexing - UWDM.''

LU delivers UDWDM optical system, Part II Lucent's WaveStar OLS 400G builds on the company's pioneering dense wavelength division multiplexing (DWDM) technology, used by carriers worldwide as an economical means of increasing the capacity of their fiber-optic networks. Based on Bell Labs patented research, Lucent's WaveStar system combines up to 80 high-capacity optical channels of 2.5 Gb/s each over a single fiber. The system maintains a high transmission performance, ensuring a low error rate over very long reach of up to 640 kilometers. ''We are continually pursuing new technologies that will allow us to add capacity quickly and cost effectively,'' said Frank Ianna, AT&T's executive vice president of network and computing services. ''Lucent's solution gives us tremendous flexibility in adding new capacity, further improving our unit cost efficiencies.'' WaveStar's fully-open architecture enables carriers to simultaneously mix and match for the first time combinations of 2.5 Gb/s (OC-48/STM-16) and 10 Gb/s (OC-192/STM-64) SONET or SDH channels over one fiber. Adding to its versatility, Lucent's WaveStar OLS 400G is the first system to support a combination of OC-48 and OC-192 equipment from a variety of vendors. The WaveStar OLS 400G is designed as a single broadband platform to be cost effective, even when used in small, start-up configurations. The WaveStar system gives any service provider the flexibility to upgrade up to 80 channels by adding optical DWDM circuit packs two channels at a time, rather than in larger increments. With advanced operational features such as optical add/drop and gain control built into the Lucent WaveStar system, service providers can automatically tailor channel configurations to match bandwidth needs. The WaveStar OLS 400G is available with a network management system for integrated administration of the optical and SONET/SDH layers. With no disruption to existing service, the WaveStar OLS will be upgradable from Lucent's 16-channel unit. Lucent's system, with worldwide commercial availability expected in the fourth quarter, is the first in the WaveStar family of next-generation optical networking products that will be introduced over the next few months.
