Cisco EHWIC-1GE-SFP-CU Enhanced High-Speed WAN Interface Card

The Cisco EHWIC-1GE-SFP-CU Enhanced High-Speed WAN Interface Card is a modular expansion for Cisco routers that adds a single Gigabit Ethernet port through a copper SFP transceiver, enabling flexible WAN connectivity without replacing the core platform and designed for routers that support EHWIC modules. This card presents a copper-based 1 Gbps Ethernet link via the SFP-CU module, suitable for connecting to edge devices, switches, or WAN links that rely on copper cabling, and it slots into standard Cisco EHWIC bays to extend WAN capability within existing Cisco routing architectures. Part number 73-13295-01, revision V00. It supports incremental upgrades in networks that already rely on Cisco WAN connectivity, allowing administrators to modulate bandwidth and interface availability without a full hardware replacement. The product title identifies it as an Enhanced High-Speed WAN Interface Card, aligning with Cisco’s EHWIC lineup and the 1GE-SFP-CU designation, which confirms one Gigabit Ethernet port delivered through a copper SFP transceiver.
