Cables in Computer Networks

  1. 1. CABLES USED IN NETWORKS
  2. 2. TWISTED PAIR  Twisted pair cabling is a wiring in which pairs of wires are twisted together for the purposes of canceling out electromagnetic interference (EMI) from other wire pairs and from external sources.  This type of cable is used for home and corporate Ethernet networks.
  3. 3. FIBRE OPTIC CABLE  An optical fiber cable consists of a center glass core surrounded by several layers of protective material. The outer insulating jacket is made of Teflon or PVC to prevent interference. It used fro fast information transfers.  It is expensive but has higher bandwidth and can transmit data over longer distances.
  4. 4. COAXIAL CABLE  Coaxial cables have been installed mostly for transmission of TV signals, but new technologies open the possibility of using home coaxial cable for high-speed home networking applications.  Coaxial lines can be bent and twisted (subject to limits) without negative effects.
  5. 5. PATCH CABLE  A patch cable is an electrical or optical cable used to connect one electronic or optical device to another for signal routing. Devices of different types are connected with patch cords.  It is a very fast connection speed. They are relatively short, no longer than 2 meters.
  6. 6. ETHERNET CROSSOVER CABLE  An Ethernet crossover cable is a type of cable used to connect computing devices together directly where they would normally be connected via a network switch, hub or router, such as directly connecting two personal computers via their network adapters.  Some newer Ethernet devices support the use of cross-over cables in the place of patch cables.
  7. 7. POWER LINES  Power wires are not designed for networking applications, but new technologies like Power line communication allows these wires to also be used to interconnect home computers, peripherals or other networked consumer products. Their main use is to provide power supply for network components.
