Cisco Systems announced enhancements to its much-debated IP-over-dense wavelength division multiplexing technology, and also landed another major carrier customer--Sprint--for a 40 Gbps CRS-1 IPoDWDM deployment. The improvements to the IPoDWDM modules include, according to a story at Network World, a doubling of reach in a 40 Gbps CRS-1 deployment to about 1,250 miles without regeneration; the extension of IPoDWDM to Cisco's XR 12000 and 12000 routers with a new 10 Gigabit Ethernet shared port adapter; the addition of a reconfigurable optical add-drop multiplexer to reduce provisioning on the Cisco ONS 15454 optical transport platform; the re-setting of failover benchmarks to 15 milliseconds; and the enabling of direct management of optics integrated into the router.
Meanwhile, Sprint becomes Cisco's second major CRS-1 IPoDWDM customer for a 40 Gbps project. Cable TV giant Comcast was the first. The enhancements, in particular the 15 ms. faliover--more than three times faster than the industry standard of 50 ms.--might help Cisco's cause with other carriers.
