Overview
Introduction
The ICF-1171I Series CAN-to-fiber converters are used in pairs to
connect two CAN (CAN 2.0) or two CAN FD (ISO CAN FD) devices or
networks via single-mode or multi-mode optical fiber. The ICF-1171I
CAN-to-fiber converters provide 2 kV isolation protection for the CAN
interface and dual power inputs to ensure that your CAN system works
uninterrupted.
The ICF-1171I 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 the different CAN protocols and frame
lengths. In other words, the higher layer CAN protocols, based on CAN
(CAN 2.0) and CAN FD (ISO CAN FD), can work through the ICF-1171I
Series.
To connect two CAN devices with a fiber-optic cable, two ICF-1171I
Series converters are required.
Why an ICF-1171I CAN-to-fiber converter?
• Extends the CAN Bus Transmission Distance
Typically, the total transmission distance of a CAN (CAN 2.0) or
CAN FD (ISO CAN FD) system can be extended by 2 km (multi-
mode fiber) or by 40 km (single-mode fiber) using ICF-1171I
converters. However, the reach of these exten sions depends on the
environment, architecture, etc.
• Easily Fulfil Various Communication Scenarios
Two CAN (CAN 2.0) networks or CAN FD (ISO CAN FD) networks
can communicate with each other using different baudrates. The
ICF-1171I converters can automatically detect the baudrate of the
connected CAN (CAN 2.0) device and apply the baudrate itself.
Therefore, you do not need to know the baudrate of the connected
CAN (CAN 2.0) device, making it an extremely convenient feature.
Baudrates can also be set to a predefined value via rotary switches.
Please note that Automatic baudrate detection is only supported in
CAN (CAN 2.0), not in CAN FD.
• Easily Troubleshoot Communication Issues
It is easy to check if an issue exists on the CAN bus or the fiber
link. The ICF-1171I converters come with LEDs that indicate the
fiber link state, fiber communication status, CAN bus state, and
CAN bus communication status.
