Network cables

• Network cables - are used to connect and transfer information between computers, routers, switches and storage area network.
• Two basic type of twisted pair:

  • Unshielded twisted pair ( UTP )
  • shielded twisted pair ( STP )
• Unshielded twisted pair - is the cable that has two or four pairs of wires. It is the most popular and is generally the best option for school networks
• Coaxial cable - is a copper - cored cable sorrounded by a heavy shielding.
• Types of coaxial cable exist:

  • Thicknet ( 10BASE5 ) makapalnet
  • Thinnet ( 10BASE2 ) manipisnet
  • RG-59
  • RG-6
• Thicknet ( 10BASE5 ) - is coxial cable used in network operating at 10 Mbps, with maximum length of 500 meters
• Thinnet - is a coxial cable used in network operating at 10 Mbps, with maximum lenght of 185 meters
• RG-59 - is most commonly used for cable television in the U.S
• RG-6 - is higher- quality cable than RG-59, with more bandwidth and less suscepibility to iterference
• Fiber òptic cable - is a glass or plastic conductor that transmit information using light and it also has one or more optical fibers envlosed in a sheath or jacket.
• Two types of glass fiber- optic cable:

  • Multimode
  • Single - mode
• Multimode - is the cable that has a thicker core than single- mode cable
• Single - mode - is the cable that has very thin core
• Straight through cable - is atype of twisted pair cable that is used in local area networks to connect a computer to a network hub such as a router

  • A type of cable also called patch cable
• Crossover cable - is a type of ethernet cable that is used to connect computing devices together directly
