Verizon completed a field trial carrying 100G Ethernet traffic on a metropolitan Ethernet infrastructure.
The trial, which ran from June 14 – 18, used existing Alcatel-Lucent 7450 switching equipment with new plug-in cards to place native 100GE traffic on a single fiber, creating the high-speed links. The tests were completed over 12.7 km (7.9 miles) of field fiber in the company’s Dallas area network. Alcatel-Lucent’s 7450 ESS nodes used 100 GE service interfaces with 100GBASE-LR10 optics, which are rated for distances of up to 10 km.
“With this 100G Ethernet trial, Verizon is preparing for the future and the need to meet our customers’ bandwidth needs in the metro Ethernet space,” said Jean McManus, executive director of technology for Verizon. “The network of tomorrow will include building blocks such as 100G Ethernet that allow us to scale our switched Ethernet core as access speeds and customer demands increase.”
Verizon’s SES network supports Ethernet LAN (E-LAN) and Ethernet Virtual Private Line (EVPL) metro services. E-LAN is a multipoint-to-multipoint bridging service designed for any-to-any connectivity between dedicated ports. EVPL is an all-fiber optic network service that connects subscriber locations at native LAN speeds using point-to-point Ethernet virtual connections.
This latest trial follows Verizon’s deployment of the first live 100G commercial system on its European optical core network between Paris and Frankfurt as well as a series of successful 100G technology trials the company has previously completed.
In November 2007, Verizon and Alcatel-Lucent successfully completed the industry’s first field test of 100G optical transmission on a live network route between Tampa, Fla., and Miami. In October 2008, Verizon and Nortel proved 100G transmission could perform with better tolerance for signal distortion than typically found in today’s standard 10G wavelength. In September 2008, Verizon and Nokia Siemens Networks announced they had successfully transmitted data at 100G on a single wavelength for more than 1,040 kilometers, setting a new distance record over deployed fiber and demonstrating better performance than conventional transmissionhttp://www.verizon.com

- In December 2009, Verizon began carrying live, commercial traffic over a 100 Gbps ultra-long-haul optical system on the company’s European optical core network between Paris and Frankfurt. The accomplishment marked the first time for deployment of ultra-long-haul 100G using a single channel on a production network. Specifically, Verizon deployed Nortel’s 100G solution to carry live Private IP traffic between Verizon’s core routers over the 893-kilometer (555-mile) route without modifying the system. Verizon sent a true 100G signal by using the same spacing between wavelengths that is used for a single wavelength, demonstrating the company’s drive to promote 100G in a serial fashion on just one information channel. The 100G transmission was conducted on a Verizon ultra-long-haul optical system carrying other live 10G wavelengths.
