Repeater Cabling
Table 1 lists the maximum distance between two adjacent repeaters, and between a repeater and
a station. You can use UTP level 3 cable to extend lobe length, but do not use it as a trunk cable.

All distances include patch cables and hub connections.
Table 2 shows the industry guideline for cable length between a repeater and a passive MAU.
Although cable lengths in excess of these distances are physically possible with a DECrepeater
900TL, Digital recommends that you keep cable lengths within the maximums found in the industry
guideline to allow for future network expansion and upgrade.
