The Cisco 12000 Series One-Port 10-Gigabit Ethernet Line Card (1-Port 10-GbE) increases the speed of Ethernet connections by a factor of ten, enabling service providers to more cost-effectively scale their distribution networks to higher traffic capacities and simultaneously deliver more sophisticated and higher value services without increasing complexity.Supported by the Cisco 12000 Series distributed system architecture, the 1-Port 10-GbE Line Card provides one dedicated 10-Gigabit Ethernet port that offers 10-Gigabits-per-second (Gbps) line-rate performance for IP and Multiprotocol Label Switching (MPLS) traffic. This interface operates in all Cisco 12400 Series Internet Routers, offering service providers platform flexibility in architecting their networks.
