CRS-1 Continues To Prove Its Mettle

Cisco, Sprint (and hardware partner Ciena) achieved their 40 Gbps coup by tapping a technology called Internet Protocol-over-dense-wavelength-division-multiplexing (IPoDWDM); according to Sprint, customers are clamoring for beaucoup throughput to support triple-play and other next-gen services.

It's part of a phased adoption of CRS-1 on Sprint's part: When Cisco first introduced CRS-1 four years ago, it teamed with Sprint to conduct a 40 Gbps technology trial with live-production traffic. Two years later, Sprint started rolling CRS-1 out across its core IP network. The upshot, Sprint officials said, is that it's now deployed Cisco's routing behemoth at more than 25 U.S. locations.
