Network cabling and installation
Have you ever wondered what connects computers and networks? Network cable in conjunction with related hardware (network switches, hubs, delimitation devices) enables computers to connect and transfer data to computers intranet (internal network) and the Internet. Today network cabling is used for many purposes other than computer networking. It can be used to carry video for security camera systems as well as video for cable TV and AV (audio / visual) applications. Network cabling is also used as a control cable in building maintenance systems and access control systems. There are several types of cables used for this purpose, including unshielded twisted pair, shield twisted pair, fiber optic and coaxial. In some cases, only one type of cable is used in the network, while in other cases, many different types are used. Wireless systems are becoming more and more popular but always remember that you need network cabling for wireless systems. There are still two things that make network cabling better than wireless networks: it’s more secure and reliable.
Understanding cable types
Before you can really understand how cable networking works, you need to know the different cables and how they work. Each cable is different and the type of cable used for a particular network must be related to the size, topology and protocol of the network. Here is a summary of the most commonly used cables for network cabling:
Unshielded / Shielded Twisted Pair – This is a type of cable used for many Ethernet networks. Inside the cable are four sets of wire pairs. There is a thick plastic divider that separates each pair through a cable. Each pair of wires is twisted so that there will be no interference from other devices on the same network. The pairs are rotated at different distances so they will not interfere with each other. In applications that have a lot of electromagnetic interference (EMI), such as mechanical space, you can choose to use shielded twisted pair, which has an outer shield that adds extra protection from EMI. Categories 5e, 6, 6A and 7 are the most common choices today. The twisted pair cable on the horizontal run is limited to 295 ‘. Twisted pair cable is used for many applications. Standard station cabling for computers and VOIP phones, wireless access points, network cameras, access control and building maintenance systems are some of them. This is one of the most reliable types of cables and when used, network breakdowns are less common than other cables used.
Fiber Optic – Fiber optic cable is primarily used as a backbone
Cable although it is increasingly being used as a station cable (consider FIOS). By backbone cable I mean it connects the telecommunication chambers in a space to each other. Fiber optic cable has enormous broadband capabilities that allow it to carry large amounts of information at super fast speeds. Fiber cables can cover long distances (hundreds of meters) as opposed to copper cables. Because these cables require a lot of effort and information travels so far, Fiber optic component have many layers of protective coating. Fiber cables transmit light against an electric current. Fiber optic cable requires much less power than high speed copper. Fiber optic cable is a great choice for high speed reliable communication.
Coaxial Cable – Coaxial cable usually falls within the scope of work of the network cabling installation contractor. Cox will be used for cable television locations in the area where you are laying the cable. The service provider will lay an outside cable at the point of entry. The contractor will operate the extension (usually RG-11) for the local telecom closet in the space. The service will end on a personal station run (RG-6) splitter to connect to the cable. In the center of this type of cable is a copper conductor and a plastic coating that acts as an insulator between the conductor and the metal shield. This cable is covered with a coating, the thickness of which can vary. The thicker the coating, the less elastic it will be. There are some sort of endings to Cox. There are three types of termination: compression, crimp and twist on. As long as they are done properly the best method is compression. Crimp terminations are also reliable and require the right tool for the specific connector you are using. I wouldn’t recommend turning on the twist because they are unreliable and cause problems. F connector, BNC connector and RCA connector are some of the coax connectors.
Network cabling components
Patch panel – This is the panel where all the cables of the station end up in the telecommunication room. They are usually mounted on a wall mount or floor mount telecommunication rack. Usually there are 24, 48 or 72 ports on a patch panel. Are
