10BASE5 transmitted 10Mbps over a single thick coaxial cables thus giving the name of Thicknet

  • First medium used for Ethernet
  • Part of the original 802.3 standard
  • Inexpensive and do not required configuration(no needs for hubs to extend the length of systems)
  • Technologoy is very sensitive to signal reflections
  • Cable-dependent across the whole collision domain and it represents a large single point of failure.
  • 10BASE5 uses Manchester-encoded signals.
  • Other specifications or limitations are:
  • Only one station can transmit at a time (collision will occur)
  • 10Base5 can run only in half-duplex mode (subject to CSMA/CD rules)
  • 100 stations & including repeaters can exist on any individual 10Base5 segment.
