Nortel is introducing the industry's first optical technology that
can deliver both 40G and 100G network capacity, enabling four times
the network throughput immediately while providing the foundation to
simply and affordably increase capacity tenfold as required. This
innovative capability equips carriers to keep pace with dramatically
increasing demand from bandwidth-sapping applications like IPTV,
Internet video, HD programming and mobile video phones.
Nortel's 40G/100G Adaptive Optical Engine is a
revolutionary technology platform that enables both 40G and 100G
transmission with the same ease and simplicity of today's 10G
networks. Nortel's technology enhancements allow fiber-optic cables,
thinner than a human hair, to carry vast amounts of information
globally. The current state-of-the-art networking speed is 10G
(Gigabits per second), which can support the bandwidth of 1000 HDTV
channels simultaneously. By increasing that capacity to 40G,
carriers can transmit four times the traffic over the same link and
10 times the traffic when evolving to 100G.
Two customers "TDC and Neos Networks"
have selected the new Nortel solution and trials with other carriers
are currently underway globally. Danish communications solution
provider TDC recently selected Nortel's 40G/100G Adaptive Optical
Engine for its European network and Neos Networks, a leading service
provider in the U.K., is deploying the Nortel 40G/100G Adaptive
Optical Engine solution to provide bandwidth-on-demand to their
customers. (See the related announcements: Nortel 40G Optical

"With Nortel's new 40G/100G optical
technology, carriers can now increase network bandwidth simply and
economically," said Philippe Morin, president, Metro Ethernet
Networks, Nortel. "We are seeing significant demands for
bandwidth as a result of business-to-business VPNs and the
conversion from analog to high-definition video delivery over the
desktop. In addition, every operator's plan to deliver new
revenue-generating services such as IPTV, or to sell the latest
video-enabled consumer devices, will come to nothing if these
exploding bandwidth demands aren't met. With the coming era of
Hyperconnectivity, where every device that should be connected to
the network will be connected, the staggering bandwidth demands will
only continue upwards."
"Our 40G/100G Adaptive Optical Engine
technology not only increases network capacity to accommodate the
looming bandwidth demands, but is the only one that leverages the
carriers' existing network investment to provide the most
cost-effective optical solution," Morin said.
"Growing traffic patterns with the infusion
of video are causing bandwidth constraints in carrier networks
worldwide. This trend has the potential to starve new, innovative
Internet-based websites, applications, and services of the bandwidth
they need, as well as create problems for users accessing real-time
content," said Michael Howard, principal analyst at Infonetics
Research**. "Carriers recognize this situation and are adding
network capacity and also getting in position to add capacity more
rapidly. Nortel's 40G/100G solution is particularly intriguing
because it allows carriers the use their existing 10G network with
minor upgrades to deliver 40G and all of the new capabilities that
affords. The savings in terms of equipment costs, training,
maintenance, and operations are reduced accordingly."
The foundation of the solution lies in Nortel's
breakthrough on developing technology that easily upgrades existing
10G networks to a 40G solution through simple plug-and-play
technology components. Other solutions on the market that promise to
provide 40G require new fiber optic cables to be buried across the
carriers' service area. Among the key firsts of this solution
include Dual Polarization Quadrature Phase Shift Keying with
coherent detection that allows 40G operation over a 10G network as
well as advanced digital signal processing that removes all
compensation requirements from the network, along with their
associated capital and operational expenditures. Other approaches
require costly equipment that can carry the information light
signals less than half the distance of the Nortel equipment.
The solution is built on the Optical
Multiservice Edge 6500 which enables the migration to a more agile,
adaptive, all-optical network. Nortel recently demonstrated the
agility benefits of the new technology at the recent Optical Fiber
Communication Conference and Exposition (OFC) & The National
Fiber Optic Engineers Conference (NFOEC) in San Diego, demonstrating
10G, 40G, and 100G wavelengths carried over adjacent 50GHz channels,
traversing over 1000km of three types of uncompensated fiber.
