ADVA OPTICAL NETWORKING'S FSP 3000 DEPLOYED BY P&TLUXEMBOURG TO OFFER NEXT-GENERATION BUSINESS STORAGE SERVICES

Solution delivers the power efficiency, flexibility and reliability
needed to support demanding enterprise customers

Paris, France and Martinsried/Munich, Germany. April 15, 2009. ADVA
Optical Networking today announced that P&TLuxembourg, the leading
fixed and mobile telephone operator in Luxembourg, has deployed the
ADVA FSP 3000 to offer competitive storage services to enterprise
customers.

Enterprises have rigorous requirements for dedicated connections,
especially for those based on Wavelength Division Multiplexing (WDM)
technology and needed to link remote data centers. With its huge
installed base and experience with the FSP 2000, P&TLuxembourg sought
a universal platform that enables the same level of functionality,
including high power efficiency. P&TLuxembourg also sought new
state-of-the-art features that can drive deployments over longer
distances using Raman amplification, support transmission speeds up
to 40Gbit/s, enable network automation via ROADMs (Reconfigurable
Optical Add/Drop Multiplexers) and offer improved security via
sophisticated and powerful encryption technology. Important for
P&TLuxembourg was also that new equipment be qualified with solutions
from all major storage vendors.

"The increasing growth in data-intensive, high-speed networking
applications, particularly in storage environments, drives the demand
for Ethernet and Fibre Channel solutions at higher bitrates and
longer distances," said Carlo Richartz, head of backbone deployment
at P&TLuxembourg. "ADVA Optical Networking understands this demand
and with the FSP 3000 has developed an industry-leading solution that
enables us to quickly respond to the demands of our customers."

The FSP 3000, with its unique set of low-latency cards covering a
large range of protocols, is now the main building block of the
successful high-speed enterprise connectivity business services
delivered by P&TLuxembourg. Fully managed from its Network Operations
Center and tightly integrated into P&TLuxembourg's data center
offering, the FSP 3000-based solution has already drawn numerous
customers from sectors like finance, transportation and public
institutions.

"With the successful deployment of the ADVA FSP 150 in early 2008 for
intelligent Ethernet services, the FSP 3000 constitutes another key
element of our next-generation enterprise service offering. Our
customers value the speed, stability and high availability of this
WDM solution," explained Frank Mathieu, head of enterprise solutions
at P&TLuxembourg. "It was also critical for our decision-making
process that ADVA Optical Networking's FSP 3000 holds all key vendor
qualifications in the areas of open systems, including 1-, 2-, 4-, 8-
and 10Gbit/s Fibre Channel and mainframe applications, including
ESCON, FICON and InfiniBand."

"P&TLuxembourg is always at the forefront of innovation, continually
looking for advanced and competitive network solutions that ensure
the highest customer satisfaction," commented Fabrice Jean, vice
president of sales western Europe and Latin America for ADVA Optical
Networking. "By deploying the ADVA FSP 3000, P&TLuxembourg benefits
from state-of-the-art optical features, providing a powerful and
universal solution that is easy to manage and reduces operational
expenses."
