The Cisco® CRS-1 Carrier Routing System is the industry's first carrier router offering continuous system operation, unprecedented service flexibility, and system longevity. The Cisco CRS-1 is powered by Cisco IOS® XR Software-a unique self-healing, distributed operating system. As part of a video-enabled IP Next-Generation Network (NGN), the Cisco CRS-1 Series delivers continuous, always-on operation that easily scales to support the massive bandwidth requirements of visual networking experiences such as high-definition IPTV and Cisco TelePresence. These services demand a platform that delivers predictable forwarding performance and efficient, intelligent fabric-based multicast replication. The Cisco CRS-1 Series enables the Internet and NGNs to handle the approaching zettabyte era of carrier IP communications while protecting network investments for decades to come.

Product Overview

The Cisco CRS-1 Series 4-Port 10 Gigabit Ethernet Interface Module (Figure 1) provides four line-rate, IEEE 802.3-compliant 10 Gigabit Ethernet interfaces. Physical connections can be made using modular XENPAK pluggable optics. DWDM wavelengths are supported with the proper XENPAK, enabling the Cisco CRS Series router to be directly connected into an optical filter module, such as the Cisco ONS 15454 reconfigurable optical add-drop multiplexer (ROADM). This allows service providers to increase efficiencies, improve reliability, and reduce operational and capital costs through elimination of expensive and bulky optical transponder equipment, even as video-based applications rapidly increase traffic in their DWDM networks.
