Cable and optical fiber

The cable is generally considered to be made of insulation and protective layer of conductors insulated from one or two wires, and transmit electricity or information from one to another. In the broad sense, the equipment with metal as a Transmission signal.

Youjie said that the cable is used to conduct electricity.

Generally made by the following metal: copper electricity after silver, heat conductivity after gold, silver; Corrosion resistant, there is no, good plasticity, easy to welding, useful. Copper alloy is primarily progressive copper wear resistance, corrosion resistance and mechanical physical properties.

The metal has the highest conductivity and thermal conductivity, with excellent corrosion resistance and oxidation resistance, easy to welding; First for coating and clad sheet; Gold, nickel, used as a High Temperature Wire agent.

Iron ( steel ), often made of reinforced materials, such as gangxinlv, copper clad steel, aluminium cladding steel wire, etc. Zinc, used as a wire / steel tape / tiedaoti coating to protect against corrosion. Tin, made of steel wire / copper wire, used for corrosion protection and is conducive to the welding of copper wire.

Optical cable

Optical fiber, short for optical fiber, is a fiber made of glass or plastic, and can be used as a tool of light. The transmission principle is' full reflection of light'.

General fiber and optical fiber terms will be confused. Most fiber must be covered by a few layers of protection before application, the cable is called fiber cable. The protective layer and insulation layer of the optical fiber can prevent damage to the fiber from the surrounding environment, such as water, fire, electric shock, etc. Optical cable is divided into: cable sheath, fibers, buffer layer and fiber. Fiber and coaxial cable are similar, just no mesh shield. The base is the glass core of light.
