Ci-SF11/12/21/22 Series

Overview of RS-485 Serial Fiber Optic Repeater

Ci-SF11/12/21/22 series provides a fiber converter solution to extend RS-232 or RS-422/RS-485 transmission distance up to 2KM over multi-mode fiber or 20KM over Single mode fiber . 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 data transmission over EMI resistant fiber at speeds up to 115.2Kbps for RS-232 or up to 2Mbps for RS-485/422. 

Ci-SF11/12/21/22 series supports single and dual optical daisy network. The dual fiber inputs allow connecting multiple devices in a cascade or "daisy chain" fashion 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 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.

Ci-SF11/12/21/22 series converter 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.
