Moxa ICF-1170I series is a CAN-to-fiber optic converter that secures data transmission by using fiber optic transmission to provide complete isolation and protection against EMI.

Moxa ICF-1170I series can separate and protect critical segments of the system from the rest of the CAN network and is protocol independent, allowing it to work with all of the different CAN protocols and frame lengths. To connect two CAN devices with fiber optic cable, two ICF-1170I series converters are required.

Fiber Test Mode
Moxa ICF-1170I has a special feature called Fiber Test Mode, activated with a DIP switch on the ICF-1170I’s outer panel. Fiber Test Mode can be used to test the fiber cable between two ICF-1170I units and provides a simple way to determine if the fiber cable 
is transmitting data correctly. When in Fiber Test Mode, the fiber transceiver (TX) will send out a data  signal continuously and the “Fiber TX” LED will light up. On the other side of the connection, when the ICF-1170I fiber transceiver (RX) receives the 
data signal form the TX side, the “Fiber RX” LED will light up.

Dual Power with Alarm Contact Output 
ICF-1170I supports dual power inputs for redundancy. When one power input fails, the relay will be triggered. Be sure to install the dual power inputs for the ICF-1170I series, and choose the correct relay output when connecting the alarm

Why Convert CAN to Fiber?

1) Immunity From Electrical Interference
Fiber is not affected by electromagnetic interference or radio frequency interference; consequently it provides a clean communication path and is immune to crosstalk.

2) Insulation
Optical fiber is an insulator; the glass fiber eliminates the need for using electric current as the communication medium. 

3) Security
Optical fiber provides better security compared to traditional electrical signals transmitted through a wire or radio waves transmitted through the air. Since the light rays travel down the  center of the fiber, it is extremely difficult for them to escape. It is nearly impossible to tap into a fiber optic cable, and even if a tap is successful, it is possible to detect the tap by monitoring the optical power received at the termination point.

4) Reliability & Maintenance
Fiber is immune to adverse temperature and moisture conditions, does not corrode or lose its signal, and is not affected by short circuits, power surges, or static electricity.
