Can Bus Fiber Optic Converter

CAN Bus Optical Converter (New Version)

CAN Bus Optical Converter(Newly Released)

Product Description:

The BE-CAN-FO CAN to single mode and CAN to multi mode optical Converter support all the transmission speeds (transmission rates):0-1Mbps. The BE-CAN-FO-P2S & BE-CAN-FO-P2M is a repeater used to establish a connection between two CAN bus systems via single mode or multi mode fiber optic transmission medium. The BE-CAN-FO series is specially designed for converting the electrical CAN bus signal to fiber optic communication for transmission over single mode fiber optic cables.The setting or adjustment is dependent on the transmission rate. The BE-CAN-FO optical converter is developed out based on the growing market demand for CAN Bus long distance transmission without any cascading(attenuation).The transmission distance limitation of the CAN bus system will NOT be affected by different CAN baud rates. The total CAN bus communication distance can be extended over fiber optic cables. Bus errors on one CAN network will not affect the operation of another CAN network. The BE-CAN-FO-P2S & BE-CAN-FO-P2M is applied with the most advanced technology and CPU in the world,which is the foundation of the high rate transmission(1MB) over more than 20km without any cascading or delay.Thanks to the advanced technology and high performance,the BE-CAN-FO to Fiber Converters have been used in very important projects in the world.

Product Feature & Benefits:

  • Buffering function:The BE-CAN-FO CAN Bus Fiber Optic Converter can protect the data from being lost.The isolation inside the optical converter can ensure the converters work normally under harsh environments.Anti-stream function,Buffering: 1000 frames.
  • No cascading: The BE-CAN-FO has no cascading,no frame loss when data is at high rate or long distance transmission, the distance is NOT limited by the increased baud rate.
  • Reliability: Compared with other brands,the BE-CAN-FO can help build up more stable and secure networks,it can maximumly reach 6500 frames/S.
  • Buffer clearance: Clear the buffer in nominated time(For Option)
  • High rate: Up to 1Mbps(SM;20km, MM:2km)
