Cisco HWIC-1GE-SFP network card Internal Ethernet 1000 Mbit/s

The single-port Cisco Gigabit Ethernet HWIC provides Gigabit Ethernet optical and copper connectivity in a compact form factor for all Cisco Integrated Service Routers (ISRs).
The Gigabit Ethernet HWIC enables branch offices to cost-effectively use high-speed uplinks in numerous environments (Figure 1). The enhanced performance of Gigabit Ethernet in Cisco ISRs to enable new applications and services, as well as provide greater capacity for existing inter-VLAN routing and bridging capabilities. Additionally, branch offices can now connect to metropolitan-area networks (MANs).

For flexibility, the HWIC includes one Small Form-Factor Pluggable (SFP) slot to carry any Cisco copper or optical SFP (Table 1), allowing customers to use different SFPs for special distance, cost, existing infrastructure, and future expansion requirements.
Cisco IOS Software provides enhanced capabilities such as quality of service (QoS), Multiprotocol Label Switching (MPLS), IP Security (IPSec), and Layer 3 VPNs. Since this is a true routed port card, the user can configure an IP address directly on the HWIC-1GE-SFP interface and does not have to configure the port for VLAN trunking as is done in Switched Virtual Interface (SVI) configurations.
