Ease of Use:

  • The new Gen II CAN Fiber Optic Bridge offers a simplistic approach for EMI/EMC testing using fiber optic signal communication.
  • All necessary components for connecting data monitoring equipment to a vehicle bus are included in the kit

Connection Process:

  • Place the local and remote bridge modules into position
    (EMC chamber/monitoring equipment)
  • Connect the bridges together using the fiber optic cable provided
  • Set the bridge modules for proper termination and protocol
  • Connect the vehicle bus to the remote module using the high density 15 pin D connector.
  • Connect the monitoring equipment to the bridge module using the high density 15 pin D connector.
  • Begin EMI testing initiatives.
Fiber Optic Chamber

• Transmits signals between a Device Under Test (DUT) and monitoring equipment
• Provides optical isolation of vehicle networks during EMI/EMC testing
• Compatible with all CAN protocols
• Quick and easy set up with user friendly controls
• Only requires two fibers between bridge and satellite module
• Exceeds or meets automotive EMC testing specifications
   • Radiated emissions
   • Bulk current Injection
   • Radiated susceptibility
• Rechargeable batteries provide minimum 12 hours of operating time before requiring recharge


CAN FD Support
• Supports the new high speed CAN standard from Bosch
• High speed CAN arbitration phase to 1 M bps
• Data Phase to 5 M bps

Single Wire CAN Support
• Normal and High speed modes
• With or without tool termination resistor
• Fully compliant to GMW3089 V2.4 and J2411 Single Wire CAN specification for Class B in-vehicle communications
• Accurate pass-thru of High Voltage Wakeup signals at Normal bus speeds

The radiated susceptibility of our hardware is to 600 V/meter, reverb and 100 dB (uA), B.C.I.
