Network cabling requirements for ethernet

Feb 13, 2009


  • 10Base2 50-ohm coaxial is also called thinnet which is up to 185 meters and supports 30 hosts per segment. Physical and logical bus is used with AUI connectors.
  • 10Base5 50-ohm coaxial is also called thicknet which is up to 500 meters and supports 208 users per segment. It uses a physical and logical bus with AUI connectors. It is up to 2500 meters with repeaters and supports 1024 users for all segments.
  • 10BaseT EIA/TIA category 3, 4, or 5, using two-pair unshielded twisted-pair (UTP) wiring supports one user per segment; up to 100 meters long.RJ-45 connector is used along with star topology.
  • 100BaseTX EIA/TIA category 5, 6, or 7 UTP two-pair wiring supports one user per segment; up to 100 meters long. It uses an RJ-45 MII connector with a physical star topology and a logical bus.
  • 100BaseFX Uses fiber cabling 62.5/125-micron multimode fiber supports point-to-point topology; up to 400 meters long. It uses an ST or SC connector, which are duplex media-interface connectors.
  • 1000BaseCX Copper shielded twisted-pair that can only run up to 25 meters.
  • 1000BaseT Category 5 is a four-pair UTP wiring that can run up to 100 meters.
  • 1000BaseSX MMF using 62.5 and 50-micron core; uses a 780-nanometer laser and can go up to 260 meters.
  • 1000BaseLX Single-mode fiber that uses a 9-micron core, 1300-nanometer laser and can go from 3 km up to 10 km.
