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 8-Port 10 Gigabit Ethernet LAN/WAN-PHY Interface Module (Figure 1) provides eight line-rate, IEEE 802.3-compliant 10 Gigabit Ethernet interfaces. Physical connections can be made using modular 10-Gbps Small Form-Factor Pluggable (XFP) pluggable optics.

This data sheet provides detailed product specifications for the Cisco CRS-1 Series 8-Port 10GE LAN/WAN-PHY Interface Module (8-10GBE-WL-XFP). For more information about the Cisco CRS Family or about other available interfaces, visit:
