Cabling Schemes for Ethernet Networks with Momentum Components
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.

Note: 10/100 hubs/switches can be used. This will allow 100 Base T networks to
use the M1E.
