AT&T's 100GigE Field Trial Tests Cisco CSR-3

AT&T has completed a live network environment field trial of 100 Gbps backbone network technology using the newly-announced Cisco CRS-3 core router, Opnext's 100 Gigabit CFP client side modules, and Ixia's "K2" 100 Gigabit traffic generator and analyzer.


AT&T said its trial demonstrated a single-carrier 100-Gigabit transmission with real-time coherent processing on a 900-kilometer deployed ultra long-haul transport link between Louisiana and Florida using Opnext optical equipment.


Highlights of the trial include:

  • Successful single-carrier 100-Gigabit transmission with real-time coherent processing.

  • Demonstration of 100-Gigabit Ethernet single-flow router capacity.

  • Field demonstration of 100-Gigabit technology with a standards-compliant 100GBASE-LR4 single-mode MSA interface.

  • Field demonstration of a 100-Gigabit traffic generator.


"This successful field trial is a key milestone in our ongoing effort to deliver the industry's most advanced and capable IP backbone network," said John Donovan, AT&T's Chief Technology Officer. "The AT&T IP backbone network today carries nearly 19 petabytes of traffic on an average business day, supporting our wireless, wired and enterprise customers' ever-growing demand for wireless and wired broadband applications. Research and development milestones like our 100-Gigabit trials help to ensure that the AT&T network is always ready to meet our customers' needs."http://www.att.com
  • In October 2008, AT&T completed the transition of IP traffic to its next-generation, consolidated IP/MPLS backbone network. At the time, AT&T described its new full-mesh optical platform as the world's largest deployment to date of 40 Gbps transport. The company's entire U.S. ultra-long haul network -- more than 80,000 fiber-optic wavelength miles -- was transitioned to 40 Gbps technology, also known as OC-768. AT&T began turning up 40-gigabit service in volume in its network in the second half of 2006 after completing multiple field trials.
