AT&T confirmed its selection of Ciena as one of its Domain Suppliers for optical and transport equipment. 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 were not disclosed.
AT&T’s Domain Supplier program, launched last September, facilitates a more collaborative relationship with its equipment and software suppliers. 
AT&T noted that its network is now carrying 18.7 petabytes of IP and data traffic on an average business day. Its 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.
