Verizon: Optical Equals Cheaper LTE
At this week's Light Reading Live New York event about the quiet wonders of "Packet-Optical Transport Evolution," much of the talk was concerned with the difficulties of actually upgrading these key networks to 40 Gbit/s and beyond. (See LR Live: Verizon Plots 100 GigE RFP.) Unstrung couldn't pass up the opportunity, however, to question Stuart Elby, the Verizon Communications Inc. (NYSE: VZ) vice president of network architecture and enterprise technology, about how packet-optical technology relates to mobile networks.
Reducing costs, he says, will be one big effect of packet-optical, even at the edge of the radio network. See Elby's full comments by watching the video below:
Verizon isn't saying exactly how much it will spend on the optical upgrades. Its overall capital expenditures for 2008 were "a little over $17 billion," according to CTO Dick Lynch, and the company is expecting to spend around the same this year. (See MWC 2009: Verizon Picks LTE Vendors.)
"Recognize that's not all in the frontend," Elby said about the capex numbers. "We just don't talk about the other spend as much -- it's not the sexy stuff."
