Different cables can be used in different circumstances and under different conditions. Some cables are better than others. Fiber-optic cables are expensive but can be used as the trunk or backbone of your network. Standard cables are slower and take just as long to run. Optic fiber can be used to speed up Ethernet networks that normally use thin Ethernet cables or twisted-pair cables. Fiber-optic cables can also be used between floors or buildings.

Different types of Cable
There are four types of basic cables. Some cables are only suitable for certain types of installations, while others can be used in most installations. Some require very little maintenance, while others need to be maintained.
1. Coaxial cable:
There are two types of coaxial cables. The thick coaxial cable isn’t much used anymore, except in some applications. Thin Ethernet is a term for coaxial cable that is used mainly to connect networks requires a lot of maintenance, breaks easily, is bulky, and can be difficult to use. This is one of the most cost-effective choices you have.
2. Twisted-pair cable.
There are two types of twisted pair cable: unshielded twist-pair and shielded twisted pair. Twisted-pair cables are stronger than coaxial cables and can be run around corners and through walls. This type of cabling can be installed and maintained quickly and easily, which will help you save time and money.
3. Fiber-optic cable
is a type of cabling system that uses a conductor made of a special type of plastic or glass. Fiber-optic cables transmit electrical signals while other types of cables do the same. However, fiber optic cable uses laser light to carry its signal. Although fiber-optic cable is faster than other types of cables, it is still expensive and prone to being damaged. This type of cabling requires skilled technicians to install.
4. IBM cable:
This cable was created by IBM to support IBM Token Ring networks. It is a twisted-pair cable that was specifically designed to meet IBM specifications.
Coaxial cable and UTP cable should not be confused. They have slightly different specifications and properties. It’s very difficult to work with coaxial cables. UTP cable is much easier to handle. UTP cable bends easily and uses a different type of connector. UTP cable is similar to telephone cabling, and it’s frequently used for this purpose. Coaxial cable can be used for TVs, VCRs, DVD players, and CBS as well as computer networking applications.
Packaging
Different packaging options are available for cables. A coaxial cable usually has one conductor. It is typically wrapped with insulation, an aluminum foil shield layer, and fine wire (braid protection) around the aluminum outer layer. A jacket is usually added. This configuration is called simplex cable. Duplex cables typically have two conductors or fibers. This means that one fiber transmits one way and the other transmits the opposite. Multifiber cabling is cabling with a single jacket and more than one conductor. While fiber-optic cables can have thousands of these fibers in them, most electrical cables only have a handful.
Specifications for cable
There are several commonalities among all cables. First, all cables must contain either a copper conductor (or a glass tube) through which light or electrical signals can be transmitted. Insulation is required to keep the signal flowing and limit interference. Insulation also controls moisture, heat, as well as other environmental factors. Every cable must have an outer shell (or sheath) that protects and encases its inner components.
Considerations for installation
Crosstalk and attenuation are important considerations when choosing and installing cables. You can increase signal strength by placing repeaters, but it is important to place repeaters at sufficient intervals to address this issue. The signal strength and cleanliness of the network are also boosted by the workstations or nodes.
Coaxial cable connectors
A typical network using coaxial cable consists of one run of cable (also known as the backbone or backplane) and terminator connectors at each end. Grounding must be done at one end of the cable. Through a T-connector, each workstation or node in the network is connected directly to this cable.
T-connectors are used to connect thin Ethernet (RG58) cabling directly to the backplane. Every T-connector should have a terminator connector or butt, and at least one end must be grounded. This is why you should use a 50-ohm terminating resistance. Next, connect the cables using bayonet nuts connectors (BNCs). You can also use BNCs for connecting two devices or components. These connectors are protected from liquids and dirt by having several layers of black electrical tape around them. This network is also the easiest to maintain.
Conclusion
It doesn’t matter if it’s fiber optic, coaxial or twisted-pair or IBM cabling, it can make or break an installation. This quick overview of the basics of network cabling will help you to install your cables.
