ETH-2 Ethernet Specifications (N10-008) (42) | Questions
and Answers 2024 Update
What is the maximum cable length for most Ethernet standards that use twisted pair cables? **
Answ** 100 meters
Which twisted pair cable category should you use on a 1000BaseT network? ** Answ**
CAT5e because it provides better crosstalk protection than CAT5
What is the advantage of using single mode cable on a 1000BaseLX network? ** Answ** If
you use a multimode fiber, the cable maximum length is only 550 meters, but if you use single
mode cable, it can be up to 10km long.
What is the difference between 10GBaseSR and 10GBaseSW? ** Answ** The SR stands for
'short range, while the SW indicates that it is used for Ethernet over SONET
What are the two standard Ethernet networks? ** Answ** 10BaseT
10BaseFL

10BaseFL: 10 mbps (full duplex)
What kind of cabling is used for 10BaseFL networks and what is the maximum length? **
Answ** Fiber optic
