Network Cabling Types And Specifications

The network cabling transfers data connect and information between routers, computers, storage area networks and switchers. The following information outlines the types of network cabling and discusses how to choose the right kind for your installation from the network cabling company in Dubai. Learn about Twisted pair, Coaxial, Fiber optic, RS-232, and Ethernet cabling. Once you know which type is right for your installation, you can choose the proper cable for your project.

Twisted pair:

Twisted pair network cabling is available in two main types: shielded and unshielded. Shielded twisted pair (STP) provides better protection against electromagnetic interference and can carry more data per unit. On the other hand, the unshielded twisted pair has no metallic shielding and is used only for short-distance transmission.

Coaxial cable:

There are many kinds of network cabling, and each type serves a different purpose. Coaxial cables carry high-frequency electrical signals. These cables are commonly used for telephone systems, high-speed computer data buses, and cable TV networks. Each pair has a varying impedance and is protected by a plastic sheath or mesh. Coaxial cables have a long history in computer networks and are one of the most common types of network cabling.

Fiber optic cable:

One of the most common types of network cabling is fiber optic cable. This cable type has five distinct parts: a core made from optical fibers and several protective layers around it. These components ensure optimum signal transmission and eliminate electrical interference, making fiber optic cabling the perfect choice for places where electricity is in short supply. The fiber optic cable also resists environmental hazards such as moisture and sunlight and can be used for networks between buildings.

RS-232 cable:

RS-232 is an interface for connecting computer terminals with modems. Its name is derived from the Electronic Industries Association, originally designated as EIA232. Various standard versions have evolved, but the most popular one, RS-232C, defines the cable’s electrical characteristics. The connectors support various functions, including handshake pins, voltage levels, and line impedance.

RS-232 cables can run for over 500 feet. The cable length, however, is not the only parameter to consider. Maximum cable length is usually defined as the total line capacitance. The total line capacitance can be approximated using a simple formula. The sum of the mutual capacitance between signal conductors, conductor-to-shield capacitance, and stray capacitance can be calculated to find the total cable length.
