EHWIC-1GE-SFP-CU network

The Cisco EHWIC-1GE-SFP-CU-RFB is a used or refurbished single-port Gigabit Ethernet WAN interface card for Cisco Integrated Services Routers. It adds a choice of optical or copper network connection to a compatible router.

Its dual-mode design combines one SFP slot with one copper RJ-45 port. The SFP connection supports 100/1000 Mbps, while RJ-45 supports 10/100/1000 Mbps. Only one of these ports can be active at a time, so the card lets a router use the connection type suited to its network link.
