Repeater
A repeater is used to relay or transfer signals. It is used for communication between segments using
different media, to extend the length of a segment, to increase the number terminals that can be
connected, or to convert from one cable type to another. A repeater reads the electronic signals from
one segment, amplifies the signal as required, and sends it to all the segments connected to the
repeater.
The maximum transceiver cable length that can be connected to the repeater is 50 m. However, we
recommend using transceiver cable lengths of 2 m or less to prevent problems caused by noise. Pay
attention to the SQE switch settings.
