CAN (Control Area Network) Copper to Fiber Converter - Terminal Blocks
  • CAN copper (TB) to multi-mode fiber (ST) bi-directional conversion
  • Works with various CAN protocols and frame lengths
  • 2000V optical isolation protection from surges and spikes
  • Data rate: up to 250 kbps (bit-wise enable)
  • DIN rail mount enclosure – ideal for industrial cabinets
  • 10-30 VDC external power required (not included, sold separately)
Model BB-BB-CANFB isolates and protects your CAN (Control Area Network) system from component killing surges and transients in noisy and harsh environments. Model BB-CANFB is a copper-to-fiber, fiber-to-copper converter that provides optical isolation for CAN systems. It separates and protects critical segments of the system from the rest of the CAN network. It is protocol independent, allowing it to work with different CAN protocols and frame lengths. Model BB-CANFB converter is used in pairs, one for each side of the fiber. The CAN side is connected to the system via terminal blocks. Fiber is connected via ST connectors (multi-mode). Model BB-CANFB is housed in a rugged DIN rail mountable box, making it easy to install in industrial cabinets. A 10-30 VDC power source is required (not included, sold separately). According to the CAN specification, the CAN network must be terminated at both ends. Networks not properly terminated may have data errors or miss the data completely. Model BB-CANFB creates two new ends on the CAN network. Space is provided on the board for a termination resistor, R8. A 120 Ohm resistor is recommended for termination. If the BB-CANFB is not at the end of the network, it should not be terminated. Model BB-CANFB is bit-wise enabled, allowing it to automatically adjust for different baud rates. Bit-wise enable only enables the driver on every low bit received. It also disables the driver on the receive side for the low bit plus a maximum of 2µ sec. This prevents data from echoing back from the BB-CANFB, but allows the nodes to respond back. The maximum fiber length used depends on the baud rate, the BB-CANFB, and length of copper wire used. The CAN bus requires a response in one bit time.
