The Communication Cables All Over the World

The 21st century is an information age. Information technology is well developed. No matter what time and what place, you can quickly know the latest information around the world. Where to travel during the holiday, when to book the ticket, what happened during your vacation at your hometown, or any other kinds information, you can quickly know because of the strong information network. Then, how does the information travel around the world? Here let's talk something about the basic hardware facility, which we called cables, or wires.

As we can see, the cables http://www.ecvv.com/company/kaile/products.html are made of the one or more root insulated conductors with insulation and protection layer outside, which can deliver electric power or information from one place to another.

The cables always include bare wire and electromagnetic wire, insulation wire, power cable, communication cable and fiber optic cable. They are mainly used for electric power delivery, telecommunications and other related data transportation. "Wires" and "cables", there are no strict boundaries between the two. Usually, the one with less number of core cables, small diameter and simple structure is known as wire. The one without insulation layer is called bare wire. Then the other types are called the cable. Here we will emphasize on knowing the communication cables.

Communication cables are used for the transmission of telephone, telegraph, fax, television and radio programs data and many other kinds of information signals. They are made of one or more insulated wires twisted together. Compared with open wires, they are of larger communication capacity, more stable transmission ability, better security feature, higher ability against natural conditions and external interference, as well as many other advantages.

Cables are called communication cables because they are used for short-range audio communications, high-frequency carrier and long-distance data and signal communication. It is one of China's five major cable products. According to the use purposes and scopes, they can be divided into six series, which are urban communication cable, long distance symmetrical cable, coaxial cable, submarine cable (including undersea and coaxial undersea cable), fiber optic cable and RF(radio-frequency) cable. The production of communication cables developed well. Many manufacturers and suppliers are distributed all over the world. Cables all over the world connected to each other, so that formed a powerful communication data transmission network.

With the development of power industry, data communications, urban rail transit industry, automotive industry and ship building industry, the demand for wires and cables will grow rapidly, so there is great developing potential for the future wire and cable http://www.ecvv.com/product_directory/cable.html industry.
