The Versatility of Network Cable

network-cableNetwork cable, also known as twisted-pair cable and usually designated Cat5e, Cat6 or Cat7 (also known as CatX cable) has many uses other than just for connecting computers to the internet.

Because of it’s construction CatX cable is very good at rejecting noise. Other cable types, such as co-axial cable, need to use expensive and bulky screening such as copper braid, copper foil and a polyethylene or PTFE dielectric insulator.

CatX cable doesn’t need this because the pairs are twisted around each other they automatically cancel out any interference that may be introduced. This makes the cable cheaper, more flexible and less bulky which in turn makes it more affordable and easier to install.

Because of this noise rejection CatX cable is particularly suitable for long runs of video, audio, control signals and extra-low voltage power:

CCTV A single cable can deliver power and control to the camera as well as trasmitting video back to the DVR. Distances of up to 300m are possible but with some loss of quality.
Video Using the HDBaseT protocol allows full 1080p HDMI v1.4 signal to be transmitted up to 100m, fair in excess of the widely accepted maximum cable length of 15m for a standard HDMI cable.
Audio Although using CatX cable for speakers is possible it isn’t advised. However CatX cable is ideal for transmitting digital audio and optical signals can be converted to CatX cable and back again.
Control CatX cable can be used to transmit IR signals from a TV to hidden AV equipment, or it can be used to control blinds, curtains, lighting and so on.
 Power CatX must not under any circumstances be used to carry 230Vac power as this constitutes a significant and real danger. However it can be used for 12Vdc and 24Vac power for applications like CCTV and automation.
