Telefonica and Cisco completed the Internet protocol over wavelength-division multiplexing (IPoDWDM) trial using integrated coherent 100 Gbps optical interfaces in the Cisco® CRS Carrier Routing System (CRS) to prepare Telefonica's network for growth and services. IPoDWDM is an advanced technology that enables high-speed Internet services over existing DWDM networks, thereby eliminating the need for network upgrades and accelerating the introduction of new higher-speed, Internet services.

With the explosive growth of IP traffic driven by video, mobile and cloud services and business applications, service providers are looking for ways to increase network capacity while also increasing network availability and reliability to deliver Next Generation Internet experiences. The recently completed trial used Cisco's CRS core router generating a standards-compliant 100 Gbps "alien wavelength" directly into Telefonica's existing submarine network between Boca Raton, FL., in the USA and Puerto Rico. The total distance was a record-setting 4,000 kilometers (nearly 2,500 miles). The underwater round trip span consisted of DWDM transport systems from multiple vendors -- the longest such IPoDWDM test ever completed. Additional shorter tests using only terrestrial fibers were also successful.
