Cabling Schemes
Introduction In a standard Ethernet cabling scheme, each device connects via a cable to a port
on a central Ethernet hub.
Length The maximum length of cable between devices depends on the type of hub used,
as shown in the following table:
Cabling with
Traditional Hubs The following illustration shows the maximum number of hubs and the maximum
cable length between devices when using traditional (non-switching) hubs:
Type of Hub Max. Cable from
Device to Hub Max. Hubs Between
Any Two Nodes Max. Cable Between Most
Distant Nodes on Network
Traditional
(Non-switching) 100 m 4 500 m
Switches 100 m Unlimited Unlimited
Note: 10/100 hubs/switches can be used. This will allow 100 Base T networks to
use the M1E.
