Meeting metro capacity with cost-reducing fiber infrastructure

摘要

Though difficult to quantify, signs indicate that some level of infrastructure growth is likely the latter half of this year and into next year. Networks are running at historically high capacity utilization levels. Worldwide Internet traffic, which is continuing to double every , year, is forecast to reach 5,175 petabits per day in 2007 from 180 petabits per day last year. In addition, the Federal Communica-tions Commission's initial rulings in February freeing the incumbent local-exchange carriers from unbundling fiber to the home (FTTH) loops and the Defense Information Systems Agency-led GIG-BE project point to increased telecommunications spending in the access and government sectors.
