Ethernet Standards Ch4

Question 1

10BaseT

Answer 1

Speed: 10Mbps
Distance: 100 Meters
Cable Type: Cat3 or better UTP RJ45

Question 2

100BaseTX

Answer 2

Speed: 100Mbps
Distance: up to 100 Meters
Cable Type: Cat5 5e or 6 UTP RJ45

Commonly known as Fast Ethernet

Question 3

100BaseFX

Answer 3

Speed: 100Mbps
Distance: up to 2000 Meters
Cable Type: Fiber ST SC Multimode Fiber
Wavelength: 62.5/125 Mcron

Question 4

100BaseSX

Answer 4

Speed: 10Mbps
Distance: up to 550Meters
Cable Type: Fiber ST SC LC Multimode Fiber
