AT&T Selects Additional Domain Network Equipment Supplier

Ciena Selected for Optical Transport Network and Metro & Core Transport Domains

Dallas, Texas, April 20, 2010

newsrelease

AT&T Inc.* today announced the selection of Ciena as one of its Domain Suppliers for optical and transport equipment needed for its industry-leading IP-based network.  

The multi-year selection covers equipment used to expand and maintain AT&T’s metropolitan and long-haul network infrastructure, including use of coherent 100G wavelength capability and OTN switching.

Financial terms of the supplier agreement were not disclosed.

“After conducting an extensive review of multiple optical and transport equipment suppliers, we’re pleased to extend a long-standing relationship with Ciena.” said Tim Harden, President of AT&T’s Supply Chain and Fleet Operations organization.

AT&T’s Domain Supplier program, launched last September, facilitates a more collaborative relationship with its equipment and software suppliers, enabling AT&T to have the best technologies in place to serve its customers.  The program is also designed to ensure that the company’s network technology investment accelerates AT&T’s move toward a network that is well-equipped for the future. 

Domain Suppliers will support AT&T in its continual efforts to innovate and invest in one of the world’s most advanced and powerful networks.  The AT&T network carries 18.7 petabytes of IP and data traffic on an average business day, the equivalent of transporting the entire digitized Library of Congress more than 250 times.  This traffic volume has doubled over the last four years.  The network includes more than 880,000 route miles of fiber-optic cable. 

AT&T in January announced total 2010 capital expenditures are expected to be between $18 billion and $19 billion, a level framed by the expectation that regulatory and legislative decisions relating to the telecom sector will continue to be sensitive to investment.
