The AT-GS2002/SP Ethernet bridging converters are designed to extend the distance of your network by interconnecting LAN devices that are physically separated by large distances. These bridging converters have the functionality to connect any managed/unmanaged 10 Mbps, 100 Mbps, or 1000 Mbps (1 Gbps) switch or hub using standard 10/100/1000T RJ-45 connections & convert the electrical signal to fiber optical signal via its SFP port.
