Ethernet Cabling Summary

Let’s summarize the information we have just examined regarding Ethernet. Table 29 and Table 30 contain the key information about cabling for both coaxial and UTP Ethernet. Table 31 contains a list of Ethernet types along with their cable lengths and data rates.

**Table 29: Coaxial Ethernet Workstation and Cabling Requirements**
Cable Type	Popular Name	Length	Nodes	5-4-3 Rule
10Base5	Thicknet	500 meters	100	Yes
10Base2	Thinnet	185 meters	30	Yes

**Table 30: UTP Ethernet Workstation and Cabling Requirements**
Cable Type	Speed	Length	Nodes	# of Pairs	Category
10BaseT	10Mbit	100 meters	1024	2	3
100BaseT	100Mbit	100 meters	1024	2	5
1000BaseT	1000Mbit	100 meters	1024	4	5

**Table 31: Ethernet Cable Types, Lengths and Data Rates**
Cable Name	Cable Type	Maximum Length	Data Rate
10Base5	Coax	500 m per segment	10 Mb/s
10Base2	Coax	185 m per segment	10 Mb/s
10BaseT	UTP	100 m per segment	10 Mb/s
10BaseF	Fiber	4 Km	10 Mb/s
100BaseT	UTP	100 m per segment	100 Mb/s
100-VGAnyLan	UTP/STP	Varies with cable type	100 Mb/s Fast Ethernet
100BaseT4	4 pair Cat 3, 4, or 5 UTP	100 m per segment	100 Mb/s
100BaseTX	2 pair Cat 5 UTP or Cat 1 STP	100 m between the hub and network node	100 Mb/s Fast Ethernet
100BaseFX	Fiber	2 Km	100 Mb/s Fast Ethernet
Category 3	UTP	100 m, including patch panel and patch cables	10 Mb/s Ethernet, 4 & 16 Mb/s Token Ring and VGAnyLan at 16 MHz
Category 5	UTP	90 m (100 m including patch panels and patch cables)	100 Mb/s Fast Ethernet at 100 MHz
