ICF-1170I Series Serial Media Converters > Serial Media Converters 14-30 www. m oxa. com 14 Fiber Test Mode Introduction Specifications ICF-1170I Series The ICF-1170I series CAN-to-fiber converters are used to convert CAN signals from copper to optical fiber. The converters come with 2 kV optical isolation for the CANbus system and dual power inputs with Fiber Test Mode can be used to test the fiber cable between two ICF-1170I units, and it provides a simple way to determine if the fiber cable is transmitting data correctly. When in Fiber Test Mode, the fiber transceiver (TX) will continuously send out a data signal and the “Fiber alarm contact relay to ensure that your CANbus system will remain online. TX” LED will light up. On the other side of the connection, when the ICF-1170I fiber transceiver (RX) receives the data signal from the TX side, the “Fiber RX” LED will light up.
