HT403RI-1R3/2R3 provides 1-2 RS232/422/485 serial ports for transmission via optical fiber, supports various optical fiber network topologies: point-to-point communication, chain network, star network and redundant ring network with self-healing protection, etc., and can be grouped together on this basis to form a more complex network topology, with a ring network with self-healing protection function. The product breaks through the traditional serial interface. The product breaks through the traditional serial interface communication distance and communication rate of the contradiction, at the same time, also solved the electromagnetic interference, ground loop interference and lightning damage problems, greatly improving the reliability of data communication, security and confidentiality.

Structure&apperarance:
The product supports a variety of fibre-optic network topologies: point-to-point communication, chain network, star network and redundant ring self-healing protection topologies, and can be grouped on this basis for more complex network topologies.
◆ Point to Point Applications: Some individually dispersed bus nodes need to communicate with each other over long distances, or are subject to serious interference and need to be electrically isolated.
◆ Chain (Line) Application: Multiple bus nodes need to communicate with each other over long distances, or multiple nodes need to be completely isolated from each other to prevent interference.
◆ Star applications: when there is a need to change the bus chain topology between multiple nodes, or when there is a need for complete electrical isolation between multiple nodes;
◆ Circle: Application: Redundant fibre-optic links are required between multiple nodes to ensure reliable bus communication.
The application of this series of products is flexible, at the same time, this series of products can use dual optical ports to achieve dual-fiber ring network redundancy function, when a fiber optic failure, the system will rebuild the network link within 10ms, to protect the normal communication of the system, to achieve the self-healing protection function of the bus signal transmission, the system will be automatically restored after the elimination of network failures;
