Ci-CF11/CF12 Series

Overview of ControlNet Fiber Optic Repeater

This series is designed for Fiber Optic Repeater which support ControlNet fieldbus and redundancy fiber optical ring network. The use of glass fiber transmission technology enables a very large transmission range and ensures optimal protection from EMC effects on the transmission path. This series adopts large-scale FPGA design and original technology, which can secures transparent transmission over EMI resistant fiber for ControlNet protocol.

This series supports single and dual optical daisy network. The dual fiber inputs allow connecting multiple devices in a cascade or Daisy-chain topology  for fiber redundancy. The redundant ring enables a very high level of transmission reliability. When fiber optic error somewhere, the system will rebuild the network link within 20ms to guarantee the normal system communication, achieve the function of signal transmission self-healing protection. The system will recovery automatically after the network troubleshooting. This series products adopt Comark own R&D professional network protocol Ci-Ring, no need any set, no need root knot, quickly finishing the network function of ring closing and ring opening.

Fiber Optical repeater provides a fiber link monitoring function to detect the communication errors on both sides of the fiber connection. When a communication error occurs, a red LED status indicator will turn on and the alarm output will activate. 

Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in various situations like industrial control, process control and traffic control.
