PHYSICAL TRANSMISSION MEDIA

  1. 1. CHAPTER 3: COMPUTERNETWORKS ANDCOMMUNICATIONSPhysical Transmission Media
  2. 2. At the end of the lesson, student shouldbe able to:Identify the various types of cables: Twisted-Pair Cable Coaxial Fibre Optic
  3. 3. Twisted Pair CableDescription: Consists of two strands of insulated copper wire, twisted around each other. Multiple twisted can be combined into a single cable. Can reduces interference from electrical field.How signal pass through: Transmit data by means electrical signal
  4. 4. Coaxial CableDescription: Consists of a single copper wire surrounded by at least three layer an insulating material, braided wired, plastic coating.How signal pass through: Transmit data by means electrical signal
  5. 5. Fibre OpticDescription: Consists of dozens or hundreds of thin strands of glass that use light to transmit signal. Each strand, call optical fibre, is as thin as a human hair.How signal pass through: Transmit data as pulses of light through tiny tubes of glass.
