The maximum length of a twisted-pair cable segment is 100
meters. Cabling should be Category 3 or better.
Between any two end-stations in a collision domain, there may be
up to five cable segments and four intermediate repeaters (hubs,
hub stacks, or other repeaters).
If there is a path between any two end-stations containing five
segments and four repeaters, then at least two of the cable
segments must be point-to-point link segments (e.g., 10BASE-T,
10BASE-FL), while the remaining segments may be populated
(mixing) segments (e.g., 10BASE-2 or 10BASE-5).
Fast Ethernet (100Mbps) networks need to respect the following
connectivity rules:
The maximum length of a twisted-pair segment (that is, the
distance between a port in the hub to a single-address network
device such as a PC, server, or Ethernet switch) is 100 meters.
Cabling and other wiring should be certified as Category 5 or
shielded twisted pair (STP).
The maximum diameter in a collision domain is about 205 meters
using two Class II hubs (or hub stacks).
Between any two end-stations in a collision domain, there may be
up to three cable segments and two Class II hubs or hub stacks.
Hub to End-Station Connection
After the hub properly installed, it can support up to eight end-station
connections. Fast Ethernet connection requires either a Category 5
UTP cable or an STP cable. These cables can be up to 100 meters
long.
Ethernet connection requires a Category 3 or better UTP cable. It is
recommended that you use Category 5 cabling for all connections, in
order to make it easier to transition all stations to 100Mbps.
You can connect any combination of PCs, servers, and other single-
address network devices to the eight twisted-pair ports using
straight-through twisted-pair cables. These cables should not be
