FO Distribution Module SDU/FO
The module SDU/FO was designed for the distribution of fiber optic signals. The input
signal is connected via a ST type connector, electrically distributed and spread to twelve
output buffers. The signal outputs are available via ST type connectors as well.
The SDU/FO contains a signal detection for the input. This ERROR state is signed by
the Alarm LED on the front panel, and by the ERROR output connector on the back
panel.
During "OK" State the connection of the Relay is between: comm - on
During "ERROR" State the connection of the Relay is between: comm - off
