INEXIO RELIES ON DWDM TECHNOLOGY FROM ADVA OPTICAL NETWORKING

Virtually unlimited scalability for the same cost as an SDH leased
line

Norcross, Georgia, USA and Martinsried/Munich, Germany.
December 9, 2008. ADVA Optical Networking announced today that
inexio, a service provider in southwestern Germany, has deployed DWDM
technology (Dense Wavelength Division Multiplexing) based on the
ADVA FSP 3000 platform. As a result, inexio has dramatically
increased the transmission capacity of its telecommunications
backbone and is now equipped with a state-of-the-art Ethernet- and
MPLS-based network capable of easily keeping pace with all customer
requirements.

The cost for implementation and operation of the new network is
barely more than that of the previously leased and managed SDH
(Synchronous Digital Hierarchy) connection, while the transmission
capacity has grown from only 2.5Gbit/s to 320Gbit/s. As a further
benefit, the ADVA Optical Networking platform was implemented quickly
and easily, and is now being operated hassle-free by the inexio staff
after just a few days of training.

inexio KGaA operates its own next-generation optical fiber-based
telecommunications network in southwestern Germany, Luxemburg and
eastern France. The network spans a total length of approximately
1,000km and has nodes in major cities in southwestern Germany between
Frankfurt/Main, Karlsruhe and Luxemburg. Additionally, inexio
currently operates three data centers in that same region in
Saarlouis, Luxemburg and Kaiserslautern.

Established in 2007, the startup has already acquired a strong
customer base of more than 150 companies from different branches of
industry that includes Villeroy & Boch, Boehringer Ingelheim, Juris
GmbH and SES ASTRA. The ADVA FSP 3000 provides inexio with an
exceptionally scalable, cost-efficient platform for all the services
and protocols the enterprise supports, ranging from a variety of
different DSL services, VoIP and Ethernet services to enterprise
services requiring the iSCSI and Fibre Channel protocols.

"The future belongs to innovative Ethernet- and MPLS-based networks.
We are firmly convinced of that, and our own next-generation network
is a prime example," said David Zimmer, general partner of inexio.
"With ADVA Optical Networking's DWDM solution, we are now able to
quickly and efficiently meet our customers' growing needs for more
bandwidth. What's better, our costs for the implementation and
operation of the new network come to hardly more than those for the
managed STM-16 lines we used to lease. ADVA Optical Networking has
proven to be an extremely reliable, flexible partner. We are already
planning a number of new network segments that will be deployed based
on ADVA Optical Networking's solutions."

"inexio represents a new generation of alternative business carriers
that opts for future-proof technologies and is very successful
because of their choices," said Christian Cehovin, vice president,
sales for Central & Eastern Europe at ADVA Optical Networking. "The
use of DWDM technology based on the ADVA FSP 3000 guarantees extreme
scalability, reliability and efficient operation, regardless of the
applications and protocols deployed. inexio customers benefit
tremendously as a result."
