Cisco offers the three-port Gigabit Ethernet line card for the Cisco 12000 series family of Internet routers to address the needs for interconnecting devices within points of presence (POPs) at gigabit rates. The three-port Gigabit Ethernet line card is the second Ethernet-based product for the Cisco 12000 series family of Internet routers, providing a cost-effective, high-bandwidth solution. This compelling solution is sought by Internet service providers (ISPs) with large Web hosting equipment such as servers, caches, edge routers, Gigabit Ethernet switches, and so on, who are looking for cost-effective links between their Cisco 12000 series platforms and other network equipment.This new line card can be configured with up to three of the following interface types: a 1000BASE-SX multimode fiber interface with up to a 550-meter reach, a 1000BASE-LH single-mode fiber interface with up to a 10-km reach, or a 1000BASE-ZX single-mode fiber interface with up to a 70-km reach.
