Ethernet Media and Topologies

• 10Base5 (Thick Ethernet)
  • Co-axial cable (yellow)
  • 500 m/segment, 100 nodes/segment.
  • Bus topology with transceiver taps
• 10Base2 (Thin Ethernet)
  • Co-axial cable
  • 185 m/segment, 30 nodes/segment.
  • Bus topology with BNC and T-connectors
• 10BaseT (Twisted Pair Ethernet)
  • Twisted-pair cable (Category 3,5)
  • Star topology physically, but logical bus
  • Needs a HUB (12, 16 ports, stackable)
  • 100 m max cable length.
• 10BaseF (Fibre)
  • Multi-Mode fibre
  • Star like 10BaseT
  • 2km length
  • ST/SC connectors, Media-converters
