Verizon last week said it conducted a successful test of an 800Gbit/s connection across 400 miles of its ultra-long-haul fiber route between Dallas and Atlanta using ICE6 equipment from Infinera.
The effort reflects Verizon's intention to prepare its fiber backbone for the traffic increases it expects over the next few years from enterprise customers, 5G users and other Internet surfers.
Fiber remains "key to everything we're doing," Kevin Smith, Verizon's VP of technology development and planning, told Light Reading.
But some analysts argue that the noise around 800G may not ultimately result in a widespread push toward the technology when other options like 400G are on the table.
Smith explained that Verizon plans to install increasingly advanced fiber technologies, ranging from 400G to 800G, into its metro, long-haul and ultra-long-haul fiber networks. The goal, he said, is to stay ahead of the overall growth in Internet traffic, driven in large part by Verizon's big enterprise customers but also by the growing number of consumers with Verizon's 5G smartphones.
However, Smith explained that Verizon has no intention of deploying 800G fiber technology across its entire backbone. Instead, he said that over the next two to five years he expects the company to strategically deploy 800G equipment in locations where it is needed, based on the growth in traffic over Verizon's network. He declined to provide any financial details about Verizon's fiber network upgrade efforts.
Verizon has indicated it will begin commercially deploying 800G in parts of its fiber network as soon as the second half of 2020.
Over the next two years, approximately 60% of service providers (both large and small) will adopt virtualization on a wide scale across their networks, according to the latest survey report from Ovum. Why are providers making these moves? Is there an easy way to start?
Learn how and why service providers are using virtualization to transform their networks. This webinar will look at how providers are leveraging virtualization to create more flexible and agile networks while also providing a better customer experience. Expert speakers from netElastic and Heavy Reading will address the industry drivers for network virtualization, the benefits that can be realized, the challenges to face and the results of virtualization being achieved by providers today.
Key topics will include:
Current network infrastructure and the move to virtualization
Benefits and challenges of network virtualization
How providers can get started
Service provider success stories: the decision to virtualize, the solution, and results
