Ihab Tarazi, vice president of global network planning at Verizon, discussed with Lightwave the drivers for increased bandwidth demand in Europe, how Verizon has expanded its optical network capabilities in France and the UK, and the roles 40- and 100-Gbps technology will play in Verizon’s network.
“We have the ability to do 40G,” Tarazi told Lightwave. “But in reality, because most of the demand is driven by the IP connectivity, although some customer demand is there the driver for 40G is probably not as strong as 100G. We feel comfortable that we’re going to be able to do 100G Ethernet directly into the IP routers, compared to 40G, where most of it is 40G SONET or SDH. So with 40G, whatever efficiency you gain on optics, you lose it and more on the IP side, having to go to SONET interfaces or SDH.”
