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

Description:

The Cisco EHWIC-1GE-SFP-CU Enhanced High-Speed WAN Interface Card is used in Cisco Integrated Services Routers to provide additional Gigabit Ethernet connectivity through both copper and fiber interfaces for flexible WAN and LAN network integration. Commonly installed in Cisco ISR G2 router deployments such as the 1900, 2900, and 3900 Series used in enterprise branch networks, corporate WAN infrastructures, and business communication environments requiring expanded network interface capacity. Maintenance teams, network engineers, and system integrators use this interface card for router port expansion, infrastructure upgrades, replacement of existing interface modules, and deployment of flexible copper or fiber network connections. 

Applications:

The Cisco EHWIC-1GE-SFP-CU module is deployed in enterprise networking environments where routers require additional Gigabit Ethernet connectivity for WAN or LAN integration. It is commonly used in branch office networks, enterprise WAN infrastructures, and corporate communication systems where routers must connect to fiber or copper network links. Network administrators install this module in compatible Cisco Integrated Services Routers to provide flexible network connectivity options and expand router interface capacity for growing network infrastructures.
