Cisco (NASDAQ: CSCO) and Telefonica Global Solutions say they have successfully completed a trial in which they transported 100-Gbps over a Telefonica submarine network. The total distance of the test fiber-optic route was 4000 km.

Cisco (NASDAQ: CSCO) and Telefonica Global Solutions say they have successfully completed a trial in which they transported 100-Gbps signals over a Telefonica submarine network. The total distance of the test fiber-optic route was 4000 km.

The connections used Cisco’s IP over DWDM (IPoDWDM) technology in the form of coherent 100-Gbps optical interfaces on Cisco’s Carrier Routing System (CRS), alongside DWDM systems. The CRS core router generated a standards-compliant 100G "alien wavelength" directly into Telefonica's submarine fiber-optic network between Boca Raton, FL, and Puerto Rico. The undersea fiber cable link used DWDM transport systems from multiple vendors.

The two parties also tested shorter lengths over terrestrial fibers.

"As a global company with a network spanning Europe, the Americas, and Asia, we're committed to leading the world in high-speed infrastructure that will ultimately give our customers more choice, flexibility and, innovation,” said Alejandro Martínez, vice president of Telefonica Global Solutions, Global Network and Platforms. “Using advanced IPoDWDM technology with our existing DWDM investment ensures that Telefonica can cost-effectively scale our network."

"Integrating long-haul transport interfaces such as coherent 100-Gbps IPoDWDM into routers lowers capital expenses while helping to ensure that bandwidth demands on service provider core networks can easily be met,” asserted Bill Gartner, vice president and general manager, High-End Routing and Optical business Unit at Cisco. “Proving that our nLight silicon works to 4000 km shows that IPoDWDM is ready to be deployed on many of the world's submarine and terrestrial links."
