Have you ever thought about connecting computers and networks to each other? Network cables and associated hardware (network switches, hubs, demarcation devices) allow computers to connect and transmit data over the intranet (internal network) and the Internet. Current network cabling is used for many purposes other than computer networking. It can be used for video with security camera systems, as well as for cable and audiovisual (audio/video) applications. Network cabling is also used as a control cable in building maintenance systems and access control systems. Several types of cables are used for this purpose, including unshielded twisted pair, shielded twisted pair, fiber optic and coaxial cable. In some cases, only one type of cable is used in one network, while in other cases, many types of cables are used. Wireless systems are becoming more popular, but always remember that you still need a network cable (kabelstrumpa) for your wireless system. Network cabling is always better than wireless networks: it’s safer and more reliable.
Understand the type of cable
Before you really understand how wired networks work, you need to understand 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. The following is a summary of the most commonly used network cabling cables:
Unshielded/shielded twisted pair: This is the type of cable used in many Ethernet networks. There are four sets of cable pairs inside the cable. There is a thick plastic separator that keeps each pair isolated by cable. Each pair of cables is twisted to avoid interference from other devices connected to the same network. These pairs are also distorted at different intervals so that they do not interfere with each other. In applications where there is a large amount of electromagnetic interference (EMI), such as mechanical space, you can choose to use shielded twisted pair with external shield to provide additional EMI protection.
Categories 5e, 6, 6A and 7 are current general options. The twisted pair cable is limited to 295′ in horizontal travel. Twisted pair cables are used in many applications. Standard station wiring for VoIP computers and phones, wireless access points, network cameras, building access control and maintenance systems are just a few examples. This is one of the most reliable cable types. When used, network failures are not as common as when using other cables.
Fiber: Fiber optic cable is primarily used as a main cable, although it is increasingly used as a cable (think FIOS). By the main cable, I mean that it connects the telecom rooms in a space separating them. Fiber optic cables have considerable broadband capabilities and can carry large amounts of information, such as very fast speeds. Unlike copper cables, fiber optic cables can cover very long distances (hundreds of meters). Since these cables (kabelstrumpa) must be very rigid and the information propagates over such distances, there are many layers of protective coating on the fiber optic cable. Unlike current, fiber optic cables transmit light. Fiber optic cables require less energy than high speed copper. Fiber optic cables are an excellent choice for reliable high-speed communications.
Coaxial cable: Coaxial cable is usually part of the contractor’s network cable installation work. The coaxial cable will be used in the cable TV slot of the wired space. The service provider will leave an external cable at the entrance. The contractor will expand the local telecommunications cabinet within the space (usually RG-11). Each station (RG-6) will end with a splitter to connect to the service cable.
