Cat5 cable is a good choice for long distance transmission of PC VGA video within a building. Many buildings are already wired with structured Cat5 cable for the computer network and Cat5 or Cat6 UTP cable is cost effective and manufactured to an industry standard. It is also very easy to install compared with high quality SVGA cable.
Extenders that use Catx UTP cable as the transmission medium can be referred to as Cat5 extenders, VGA extenders or Video extenders. KVM extenders refer to extenders that transmit Keyboard, Video and Mouse data over Catx UTP cable.
CatX extenders are now widely available and work by converting the analogue RGB signal to differential analogue signals for transmission over 3 of the twisted pairs within the cable. The fourth pair in the cable is used for transmission of power or audio and sometimes also for serial data transmission.
CatX extenders include the CatX Mini VP. This transmitter/receiver pair can be powered entirely by the VGA source output, a unique extender product.
CatX extenders work very well in most applications for distances from 1 meter to 300 meters (depending on the model) and at resolutions up to 2048 x 1536. CatX extenders also include receiver that can be daisy chained together using Cat5 to an overall distance of up to 2000m.
