Fast Ethernet

Chapter 2

• Rationale
  • Max drop length 100m => Max round-trip  time 1/10 of Ethernet; hence 10 times data rate

• Standard 100Base-T4

• Compatibility with 10BaseT

• UTP limitation; Use 4-pair UTP @ 25 Mbps/pair

• Alternatives: 2-pair 100BaseTX Cat 5(Max 100 m) and 100Base FX optical fiber (Max 2 km)
