You need to read about the different cables and how they operate before you can fully understand how cable networking functions. Each cable is different, and it is important to relate the type of cable used for a specific network to the network size, topology and protocol. Here is a rundown of the most widely used cables for network cabling: Have a look at Cabledan, Watford to get more info on this.
Unshielded/Shielded Twisted Pair – The type of cable used by many Ethernet networks is this. Inside the cable are four sets of pairs of wires. There is a dense plastic separator that holds the cable running isolated from each pair. Each pair of wires is twisted so that no interference from other devices on the same network can occur. At distinct intervals, the pairs are often twisted so that they will not cause interference between themselves. You may opt to use a shielded twisted pair in an application where there is a lot of Electromagnetic Interference (EMI), such as a mechanical room, which has an external shielding that adds additional EMI protection. The general options today are Category 5e, 6, 6A and 7. On a horizontal sprint, the Twisted Pair cable is limited to 295 ‘. For several applications, Twisted Pair Cable is used. Standard machine and VOIP phone station cabling, wireless access points, network cameras, access control and construction maintenance systems are only a couple. This is one of the most stable cable types, and network faults are less frequent when used than when other cables are used.
Fiber optic cable is mostly used as a backbone cable, although it is increasingly used as a station cable (think FIOS). I mean that it links telecommunication rooms within a space to each other via a backbone cable. Fiber optic cable has huge broadband capacities that allow it to carry as super-fast speeds large amounts of information. In comparison to copper cables, fibre cables can cover wide distances(hundreds of metres). Since these cables have to work very hard and the data travels such distances, on fibre optic cables, there are several layers of protective coating. As compared to electrical current, fibre cables relay light. Fiber optic cable requires a lot less energy than high-speed copper does. Fiber optic cable is a perfect choice for secure communication at high speeds.
Coaxial Cable – Coaxial cable is typically part of the network cabling construction contractor’s scope of work. Coax would be used within the room you are cabling for the cable television locations. At the point of entry, the service provider will drop off the outdoor cable. An extension (usually RG-11) to the local telecommunications closet inside the room will be operated by the contractor. To link to the service cable, the individual station running(RG-6) will terminate on a splitter. There is a copper conductor in the centre of this type of cable and a plastic coating that serves as an insulator between the conductor and the metal shield. This cable has a coating that can vary in thickness. The thicker the coating, the less it will be flexible. There are a few kinds of coax terminations available. The three types of terminations are compression, crimp and twist on. As long as they are done properly, the safest technique is compression. For the specific connector you are using, crimp terminations are often reliable and need the right tool.
