Thin Ethemet Segment
A thin Ethernet cable segment is the
length of the cable between termina-
tions. The Ethernet adapter functions
with 185 (IEEE 10Base2) or 300 meter
(extended length option) cable seg-
ments without any jumper changes.
Two types of thin Ethernet cabling are
commonly used: IEEE 10Base2 and ex-
tended length option. Pick one type
of cabling and consistently obey the
protocol of that type throughout your
network. If you mix the rules, for ex-
ample, using the two repeater links
permitted by 10Base2 with the 100
nodes per segment permitted under
the extended length option, your net-
work may have an excessive number
of errors or may not operate at all.
If your network uses standard 185-
meter cable segments, all thin Ether-
net cable segments in the network
can be up to 185 meters long. Five
standard length cable segments may
be connected in line using commer-
cially available repeaters,. The total
networic span with five standard
length segments is 925 meters. 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 be-
cause it allows you to use common
thin Ethernet components which con-
form to the IEEE standard .
If your network is using extended-
length 300-meter segments, all thin
Ethernet cable segments in the net-
work can be up to 300 meters long.
Three 300-meter cable segments may
be connected in line using repeaters.
