What is Network Cabling?
The cable is the channel through which information typically moves from a single network device to another. There are different types of cable which are usually utilized with Local Area Networks. In some situations, a network will employ just one type of cable, but some networks will utilize a variety of wire types. The kind of cable selected for a network is associated with the network’s size, protocol, and. Knowing the properties of different kinds of cables and how they relate to other aspects of a network is essential for the development of an effective network. The kind of cable employed in any network infrastructure is one of the most important factors of networking in many industries.
1. Coaxial Cable
A coaxial cable has a single copper conductor in the center. A plastic layer gives padding between the inner conductor and the braided metal shield. The metal shield prevents exterior interference from fluorescent lights, motors, and other computers.
Coaxial cabling is incredibly resistant to signal interference, but it is well known that installing coaxial cables is complex. It can support great cable lengths between network devices than the twisted pair cable. The two kinds of coaxial cabling are thick coaxial and thin coaxial.
- Thin coaxial cable (also known as thinnet). This type of coax cable has been popular in school networks, especially linear bus networks.
- Thick coaxial cable (also known as thicknet). This kind of cable has an extra protecting plastic cover that helps keep moisture away from the inner conductor. This characteristic makes thick coaxial an excellent option when running longer lengths in a linear bus network.
2. Shielded Twisted Pair (STP) Cable
This type of cable is a unique kind of copper phone wiring employed in business connections and installations. An outer shield that works as a ground is added to the traditional twisted-pair telephone lines. This type of cable may be the solution if you need to place the cable in an area with possible interference and risk to the electrical current in the UTP. Shielded cables could also help in extending the distance between the cables.
3. Fiber Optic Cable
This type of cabling consists of a central glass core enclosed by several layers of shielding materials. It eliminates the problem of electrical interference by transmitting light instead of electronic signals. This makes them ideal for special atmospheres which contain a large amount of electrical disturbance. It has converted in the standard for connecting networks between buildings due to its resistance to lighting and moisture.
Fiber optic cable has the capacity to transmit signals over longer distances than other cables like coax and twisted pair. It also can carry information at higher greater speeds.
4. Unshielded Twisted Pair
This is the type of cable that is employed for both; conventional computers and phone networking.
This cable consists of two unshielded wires twisted around each other. Because of its low cost, UTP cabling is employed for local-area networks and telephone connections. UTP cabling does not provide as high bandwidth or as good protection from interference as other cables including coaxial or fiber optic cables, but it is much less expensive and it is also easier to work with.
