DL-CANR allows the connection of CAN networks by using redundant fiber optic systems Received data telegrams are refreshed. This allows to built up structures with a high number of systems.

 

Important performance features of the transfer with POF, HCS, multimode or single mode fiber optic are the electromagnetic ruggedness, the potential separation of transmitter and receiver, as well as ranges up to 40km between two fiber optic systems. LEDs and potential-free contacts (optional) of a fault detector relay are able to signal defective states.
