Four Types of Cables You Should Know in Telecommunication Industry

If you think untangling shoelaces is complicated, it’s nothing compared to untangling and deciphering the mess of wires and cables your network uses. As we know, cables are transmission mediums in communication network. And there are many kinds of cables used for different applications or different demands. As cable is a basic topic of us guys work in telecommunication, to learn cable types well is very necessary. Here are four types of cables that we should know.

Coaxial Cable
Coaxial cable is called “coaxial” because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as a ground. Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with repeaters, can carry information for a great distance. Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feedlines connecting radio transmitters and receivers with their antennas, computer network (Internet) connections, and distributing cable television signals.

Ethernet Cable
Ethernet cable is one of the most popular forms of network cable used on wired networks. Ethernet cables connect devices on local area networks such as PCs (Personal Computers), routers and switches. Ethernet cables normally support one or more industry standards including Category 5 (Cat5) and Category 6 (Cat6) etc.

Fiber Optic Cable
Fiber optic cable consists of one or more optical fibers, each of which is capable of transmitting messages modulated onto light waves. Fiber optic cables come in lots of different types, depending on the number of fibers and how and where it will be installed. With the increasing demands of higher broadband, fiber optic cables are widely used in many modern networks.

Phone Line
A telephone line is a single-user circuit on a telephone communication system. This is the physical wire or other signaling medium connecting the user’s telephone apparatus to the telecommunications network, and usually also implies a single telephone number for billing purposes reserved for that user. Telephone lines are used to deliver landline telephone service and Digital subscriber line (DSL) internet service to the premise. Telephone lines are connected to the public switched telephone network.
