Verizon Sees More Long-Haul Demand for 100G

Verizon Communications has read the traffic trend tea leaves, and upgraded several long-haul backbone routes in the US and Europe to 100G (See Verizon Expands 100G Reach). This move comes after Verizon seemed to shift its 100G attention in recent years from long-haul to metro networks, where it said local traffic needs were heightening demand.

Glenn Wellbrock, director of optical transport network architecture and design at Verizon Communications Inc. (NYSE: VZ), told Light Reading, "We do not expect to deploy 100G on every network route, but only those routes that require higher levels of bandwidth." He added that the new 100G routes were chosen because the carrier saw those traffic needs developing.

The newly upgraded US routes included Seattle to Salt Lake City; Indianapolis to St. Louis; St. Louis to Memphis; Charlotte, N.C., to Nashville, Tenn.; and Cleveland to Detroit. Verizon also upgraded its Brussels-to-Frankfurt route in Europe.

Why this matters
Much of the industry -- not just Verizon -- had shifted 100G attention toward metro networks. Now, it's returning to relevance as a long-haul transport capability. Verizon, which has boasted a number of firsts over the years in regards to 100G in the long-haul part of the network, joins Sprint among US carriers with recent 100G long-haul announcements.

Also, amid all of the excited chatter about 200G (which Verizon has trialed), 400G, and 1T, this news is a reminder that 100G deployment is nowhere near done yet. To Wellbrock's point, carriers are being very selective about where they put 100G, and won't rush to blanket their networks with it.

Re: Is this basically about cost? Verizon said their very cost-sensitive, but that in these particular deployments it was very comfortable with the cost. The implication in this case is with routes being somewhat short (and part of longer routes still in the planning stages), they were less expensive to deploy. For example, regeneration wasn't a factor on any of these routes.

Is this basically about cost? We keep being told that 100G is getting less expensive to deploy, but if they are picking and choosing the long-haul routes on which to deploy this, I'm assuming there is still enough of a cost premium to keep 100G from being the defacto deployment.
