kvm extenders with different connections

KVM extenders

Besides the KVM which allows you to take control of multiple servers, there are also extenders. These devices enable you to locate a single server's or KVM's keyboard, screen and mouse from a remote location (optionally sometimes with a serial port and sound). In most cases, the connection is established via two units that are connected by a copper or fibre cable, one at the server side and the other on the user side. The connection is usually dedicated but may also be established over an IP network. These extensions accept all types of video output (DVI, DisplayPort, VGA, etc.).
