HWIC-1GE-SFP Cisco 1-Port Gigabit Ethernet WAN Interface Card

Any Cisco copper or optical SFP fits the single slot of the HWIC-1GE-SFP, a Cisco 1-port Gigabit Ethernet WAN interface card for Integrated Services Routers. Options include the GLC-T 1000BASE-T copper SFP, GLC-LH-SM= for LX/LH fiber, GLC-SX-MM= for SX fiber, GLC-ZX-SM= for 1000BASE-ZX, and the CWDM wavelengths from 1470 to 1610 nm such as the CWDM-SFP-1470 1470 nm CWDM SFP.

The port is a true routed interface. An IP address is set directly on the HWIC-1GE-SFP interface, with no VLAN trunking or switched virtual interface to configure. Cisco IOS adds QoS, MPLS, IPsec and Layer 3 VPNs, and the card handles 802.1Q VLAN tagging, 802.3x flow control and Gigabit EtherChannel for link redundancy. Jumbo frames run up to 9576 bytes, HSRP, VRRP and GLBP are supported, and SFPs can be inserted or removed live on all platforms. The host router limits throughput, and the card does not reach full line rate.

The card is a single-wide HWIC with no slot restrictions. A Cisco 1841, 1861, 1921, 2801, 2811, 2821 or 2851 takes one; a 1941, 1941W, 2901, 2911, 2921, 2951, 3825 or 3845 takes two; a 3925E or 3945E takes three; and a 3925 or 3945 takes four. Typical uses are a fiber uplink in a branch office, inter-VLAN routing, and Layer 3 VPN links across a metro Ethernet network. Other branch router cards are in the Cisco interface card category.
