ICF-1171I Series of CAN-to-Fiber Converters

Oct. 5, 2022
The Moxa ICF-1171I Series of CAN-to-fiber converters extends communications up to 24.85 mi. (40 km).

The ICF-1171I Series of CAN-to-fiber converters is aimed at applications that involve long distance data transmission. When used in pairs to connect two CAN 2.0 or two CAN-FD devices or networks, the converters can extend transmission distance by 1.25 mi. (2 km) on multi-mode fiber or as much as 24.85 mi. (40 km) on single-mode fiber, regardless of the CAN baudrate. The converters will transmit at data rates up to 1 Mbps in CAN interfaces and up to 5 Mbps in CAN-FD interfaces.


Since industrial networking devices are usually deployed inside space-limited cabinets, these DIN-rail mounted converters measure only 1.19 x 2.76 x 4.52 in. (30.2 x 70.1 x 114.8 mm) and come with 2 kV isolation and 2 kV surge protection for CAN port. Protected in a rugged, IP30 rated metal housing, the converters feature an operating range of -40 to 167°F (-40 to 75°C) to help overcome harsh communication environments.


To make multiple device configurations easier, the converters have a DIP switch to change interfaces between CAN and CAN-FD. In addition, there is an auto baudrate setting function for the CAN interface that eliminates the need to perform configurations. Also, in the event a communication error occurs, the user can check the built-in LED indicators to identify whether the error occurred in the CAN or fiber connection.
