Wiring in Computer Networking

Wiring in Computer Networking

In the installation of a computer network, it takes a useful medium for connecting multiple nodes such as computers, hubs, switches, routers, etc.. Media can be either wired or radio (wireless).

For media in the form of cable, which is like Coaxial Cable, Fiber Optic and Twisted Pair. And to be wireless like Bluetooth, Infrared, Wi-Fi, etc..

For now I will explain about the media cable used in computer networks.
Coaxial Cable

Coaxial cable is a cable is a cable that uses two conductors. The center of the coaxial cable in the form of wires in the cable core covered by a bulkhead and then dliliti again by webbed conductor wire. This cable has high bandwidth power

For coaxial cable, before the data is sent computer is sent, the data is first converted into an electrical signal. And then after the electrical signals reach the destination computer, the electrical signals are converted into digital signals again. This cable has a maximum distance along the 2000km installation.
Construction Coaxial Cable

The main conductor

Conductor cables should be made of solid copper cylindrical high conductivity seamless. For the diameter of the wires are not allowed to exceed 0.02 mm and 1.53 mm. As for the resistance of the conductor that is located in the (inner conductor) is 1/58 per 1 meter.

Isolation

Cable insulation made of homogeneous polyethylene and wrapped around the main conductor. For the nominal diameter of 0.97 mm and is also not allowed to exceed 0.05 mm.

Outer conductor

The conductor is made of copper tape with 0.25 mm thick with a maximum tolerance of 0.2 mm in the longitudinal position and overlapping slightly. For prisoners amounted to 1/52 per meter. At the top is wrapped in copper tape helikod with two layers of steel tape with 0.15 mm thick were used as pelindungelektromagnetik.

Hanger

Hanger here consists of seven steel wires wrapped bubbling with a size of 2 mm and a power of 3.010 kgf tensile strength.

Outer

Outer cables made of polyethylene mixed with 2% carbon black. For thick flat - flat wrappers are not allowed to exceed 2 mm and must not be less than 1.6 mm. As for the thickness of the hanger to the cable is 3.4 mm and with a height of 3 to 4.5 mm.
