Cisco® Gigabit Ethernet WAN Modules bring high-density Small Form-Factor Pluggable (SFP) and copper (RJ-45) 1 Gigabit and 10 Gigabit Ethernet (GE) connectivity to the Cisco 4000 Series Integrated Services Routers (ISRs). Providing maximum flexibility, the modules accelerate applications such as Ethernet WAN access, inter-VLAN routing, and high-speed connectivity to LAN switches and servers. The ports on these modules work as routed Layer 3 ports. Layer 2 switching between local ports on the module or between ports on the module and other ports within the router system is not supported. The port terminates Layer 2 trunks from externally connected switches, and Layer 2 trunk and VLAN information is not switched onto other ports in the system. The host router routes all traffic entering these modules. Cisco Gigabit Ethernet WAN Modules do not support Power over Ethernet (PoE). Supports twisted pair cables for durability and improved signal transfer while ensuring smooth and seamless data transfer,Up to 10x faster than standard Ethernet connection and provides high-performance,With 1000Base-T technology, get up to 1000Mbps data transfer rate over supported network cable.
