Cisco expands IP over DWDM offerings

JULY 15, 2008 -- Cisco (search for Cisco) has enhanced its Internet Protocol over DWDM (IPoDWDM) technology. Pioneered on its Cisco Carrier Routing System (CRS-1), the technology is also now available at the edge of the network.

In addition to the IPoDWDM enhancements, the company also announced upgrades to its Cisco XR 12000 and 12000 Series routers for service providers. The announcements include:

• Doubling the reach of the Cisco CRS-1 40-Gbit/sec IPoDWDM to 2,000 km (about 1,250 miles) without regeneration. The new 40-Gbit/sec physical line module interface supports deployments in virtually any geographic area, Cisco asserts.
  
• Extending IPoDWDM to the network's edge on the Cisco XR 12000 and 12000 Series Routers with a new 10-Gigabit Ethernet shared port adapter designed to enable instant bandwidth up to 10 Gbits/sec over 2,000 km.
  
• Reducing provisioning on the Cisco ONS 15454 platform with an omni-directional and colorless mesh reconfigurable optical add-drop multiplexer (ROADM). The new functionality will decrease truck rolls and lower the requirements for power, space, and cooling by more than 50 percent, Cisco believes.
  
• Increasing resiliency with proactive protection features that guard video and mission-critical data against fiber cuts by resetting failover benchmarks to 15 msec, three times faster than the industry standard of 50 msec.
  
• Enhancing the ability for service providers to deploy with separate data and transport departments with virtual transponder -- now transport departments can directly manage the optics integrated into the router.
  

"Service provider customers around the world are upgrading their networks to include an IPoDWDM interface module with the Cisco CRS-1 platform," said Kelly Ahuja, Cisco vice president and general manager of the service provider routing technology group. "By incorporating optical technologies directly into its most advanced and highest-capacity routers, Cisco offers service providers with the flexibility, scalability, ease of installation, and management necessary to maximize their returns on network investments."
