The Cisco 10000 Edge Services Router (ESR) Gigabit Ethernet interface module addresses the growing demand among Internet service providers (ISPs) for Intra-POP interconnect. Gigabit Ethernet technology is preferred by many service providers because it is standards-based, is widely implemented by many vendors and offers excellent performance. The Gigabit Ethernet module in the Cisco 10000 ESR provides a cost-effective high performance uplink to backbone routers such as the Cisco 12000 series Gigabit Switch Router (GSR). By using Gigabit Interface Converter (GBIC) technology, the Cisco 10000 ESR Gigabit Ethernet module provides the interface flexibility customers require in their rapidly evolving POPs.
