Cisco EHWIC-1GE-SFP-CU 1-Port GE + SFP Enhanced High Speed WAN Card EHWIC1GESFPCU

Description:

The Cisco EHWIC-1GE-SFP-CU Enhanced High Speed WAN Interface Card is used in Cisco Integrated Services Router (ISR) platforms to provide additional Gigabit Ethernet connectivity through both SFP fiber and copper RJ45 interfaces for flexible WAN and LAN networking deployments. Commonly installed in enterprise branch routers, corporate WAN edge devices, service provider network equipment, and distributed business infrastructures where additional high-speed Ethernet interfaces are required for network expansion and connectivity. Maintenance teams, network administrators, and system integrators use this module for router interface expansion, infrastructure upgrades, network connectivity improvements, and replacement of existing WAN interface cards in Cisco ISR networking environments.

Applications:

The Cisco EHWIC-1GE-SFP-CU module enables routers to support additional Gigabit Ethernet connectivity using either fiber optic SFP transceivers or copper RJ45 connections. It is frequently deployed in enterprise branch networks, service provider edge routers, and distributed office infrastructures where flexible network connectivity options are needed. The module allows organizations to integrate fiber uplinks, connect to aggregation switches, or extend WAN connectivity while maintaining high-speed data transmission across enterprise network architectures.
