Repeater
The repeater is a device that regenerates a transmission signal. It is used to interconnect
differing media segments, extend the media segment distance, increase the number of
terminal unit connections, or effect cable media conversion.
The repeater receives a signal from one of interconnected segments, subjects it to waveform
shaping, amplifies it to a predetermined level, and transmits (repeats) it to all the segments
that are connected to the repeater.
The maximum length of a transceiver cable connectable to the repeater is 50 m. However, it
is recommended that you limit the transceiver cable length to 2 m in consideration of noise
immunity and other factors. The SQE switch sets OFF.
