Sprint, Cisco and Ciena Fuel Next-Generation Services With 40-Gbps Circuits

July 16, 2008

Sprint, Cisco and Ciena, engaged in network transition, have announced that they are implementing 40-gigabits-per-second network capabilities on the Global Sprint Tier 1 IP Network using a technology called Internet Protocol over dense wavelength-division multi-plexing, or IPoDWDM for short.

The implementation supports the needs of Sprint customers who are looking to adopt next-generation services, grow their businesses and enable their employees to conduct day-to-day tasks, simply and immediately.

In 2004, Sprint and Cisco used CRS-1 routers to conduct the first 40-Gbps technology trial with live-production traffic. Sprint began deploying them in its IP core network in 2006. Today, Sprint CRS-1 routers are deployed in more than 25 US cities, and Sprint is working to ensure this leading-edge infrastructure technology is enabled domestically and internationally.

Sprint is further enhancing its network by deploying 40-Gbps circuits and expanding available capacity for its customers. Earlier this year, Sprint completed final testing of the 40-Gbps IPoDWDM technology and enabled their first production 40-Gbps circuit. This converged solution used the Cisco CRS-1 Carrier Routing System with built-in transponders along with Ciena’s CoreStream Agility platform to transport the wavelength across the fiber-optic network.

The implementation of IPoDWDM drives efficiencies by eliminating client connections between the router and DWDM system and increasing bandwidth four times by transmitting 40-Gbps across an existing 10-Gbps DWDM system. The integration of router and DWDM transponder components reduces network complexity and increases the scalability and resiliency of the backbone. IPoDWDM can also position Sprint to rapidly move to higher data rates (e.g., 100-Gbps) without overhauling the network infrastructure.
