Verizon Unleashes 100G on Metro Network

Driven by increased demand from online video consumption – as well as cloud and Ethernet services – Verizon is implementing 100G technology in its metro and regional networks in the U.S. where traffic demand is highest.

The carrier says this will provide the same benefits of increased capacity, superior latency and improved scalability in its metro network as it has from deploying 100G technology in its long-haul network.

Verizon is using the Fujitsu FLASHWAVE 9500 platform and the Tellabs 7100 in its metro deployment, which is the “last-mile" connectivity from the network to the customer.

“Metro deployment of 100G technology is the natural progression of Verizon’s aggressive deployment of 100G technology in its long-haul network," said Lee Hicks, vice president of Verizon Network Planning. “It’s time to gain the same efficiencies in the metro network that we have in the long-haul network. By taking the long view, we’re staying ahead of network needs and customer demands as well as preparing for next-generation services."

Verizon says the benefits of 100G scalability are especially relevant for signal performance, which is improved by using a single 100G wavelength as opposed to aggregating 10-10G wavelengths. Also, less space and reduced power requirements are needed to support 100G technology, compared with traditional 10G technology, so fewer pieces of equipment are needed to carry the same amount of traffic.

Verizon plans to expand 100G deployment as growth happens.
