Repeater
Repeaters are physical amplifiers without own processing function. It is used
to achieve large transmission distances or when the maximum number of
nodes of 64 units per twisted pair segment is exceeded.
Note:
In TP/FT-10 networks only one physical repeater is permitted between two
nodes. Otherwise Routers configured as repeaters have to be used. Such a
router also allows a media change.
The repeater always counts as a node. This means that for each segment 63
nodes + 1 repeater can be used.

ply voltage to the bus coupler, the voltage is reapplied to the bus coupler.
