Verizon Brings 100G Networking to US Due to Cloud & Video

By - Source: Verizon

Verizon is bringing 100G connectivity to its US metro network with the help of Fujitsu and Tellabs technology. The telecommunications company had previously introduced 100G in Europe in March 2011 with its long-haul network. The backbone network ran for 555 miles between Paris, France and Frankfurt, Germany.

"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," said Lee Hicks, vice president of Verizon Network Planning.

100G networks are fast, but so are 10x10G networks; where 100G connections really shine is in reliability. Running only one cable means improved performance and fewer transmission errors. Another obvious advantage to a single cable network is the need for fewer pieces of hardware, meaning reduced space and power consumption.

Verizon is running its metro 100G network on a combination of the Fujitsu FLASHWAVE 9500 Packet Optical Networking Platform (ONP) and the Tellabs 7100 Optical Transport Series. Fujitsu's Packet ONP is a modular platform with integrated ROADM, or reconfigurable optical add-drop multiplexer, support that includes 88 wavelengths. Tellabs' 7100 Series includes the 7100 Optical Transport System, the 7100 Nano Optical Transport System and the 7100 Intelligent Network Manager.

"We see the value today of starting deployment of 100G in the metro since 100G technology has performance improvements over 10G," said Hicks. "But the cost per bit of 100G in the metro currently isn’t as cost-effective as it is in the long-haul network so 100G in the metro won’t be the default technology for a while."

Verizon sees the consumption of streaming online videos and cloud services as the biggest contributors to bandwidth demand. The company is currently selectively implementing 100G technology where bandwidth demand is highest but says it will "expand deployment as growth occurs."
