Can Bus Fiber Optic Converter

CAN Bus Fiber Optic Converter (With Advanced Functions)

CAN Bus to Fiber optic Converter(No Cascading/High rate & Far distance)

Product Description:

The HFD-FO-CAN CAN bus to Fiber Converter support all the transmission speeds (transmission rates):0-1Mbps.The transmission rate is set automatically as soon as the canbus HFD-FO-CAN receives a frame. The setting or adjustment is dependent on the transmission rate. The HFD-FO-CAN CAN FO converter is developed out based on the growing market demand for CAN Bus long distance transmission without any cascading(attenuation).The HFD-FO-CAN uses the most advanced new technology 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 HFD-FO-CAN to Fiber Converter can be applied in very important projects and harsh places.

Segment monitoring at the optical line:

Each receiver monitors the optical line port connected to it for receive frames and status. If faulty frames are received by the receiver, or no single for longer than the maximum permitted time, forwarding of the received signals is blocked until the port status is OK,frames can be received again correctly.The converter can be equipped with buffering elimination function after 300ms or when the buffer is full. 

Network Topologies:

The following network topologies can be realized with the HFD-FO-CAN:

  • Point-to-point topologies
  • Multi-drop Bus

Fiber Mode: Single mode or Multi Mode

Product Feature & Benefits:

  • Buffer function:The HFD-FO-CAN CAN Bus Fiber Optic Converter can protect the data from being lost.The isolation inside the HFD can ensure the converters work normally under harsh environments.Anti-stream function,Buffering: 1000 frames.
  • No cascading: The HFD-FO-CAN has no cascading,no frame loss when data is at high rate or long distance transmission.
  • Reliability: Compared with other brands,the HFD-FO-CAN 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(20km distance simultaneously)
