Section Two
Thin Coax Ethernet Segment
A thin coax Ethernet cable segment is the length of cable between
terminations. The Trumpcard PC Card functions with 185 meter (607 foot
with IEEE 10Base2) or 300 meter (984 foot, using the extended length
option) cable segments. The two above mentioned types of thin coax
Ethernet cabling (IEEE 10Base2 and extended length option) are
commonly used. Pick one type of cabling and consistently obey the
protocol for that type throughout your network. If you mix the rules (for
example, using two repeater links permitted by 10Base2 with the 100
nodes per segment permitted under the extended length option), your
network may have an excessive number of errors or may not operate at all.
If your network uses standard 185-meter cable segments, all thin Ethernet
cable segments in the network can be up to 185 meters long. Five
standard length cable segments may be connected in line using
commercially available repeaters. The total network span with five
standard length segments is 925 meters (3,035 feet). No more than four
repeaters can be on the signal path from one node to any other node. The
standard 185 meter segment length is recommended because it allows
you to use common thin coax Ethernet components which conform to the
IEEE standard.
If your network is using extended length 300-meter cable segments , all
thin coax Ethernet cable segments in the network can be a maximum of
300 meters long. Three 300-meter cable segments may be connected in
line using repeaters. The total network span with three extended length
segments is 900 meters (2,953 feet). No more than two repeaters can be
in the signal path from one node to any other node.
