Serial port fiber optic modem - single channel ring network industrial grade (card rail type)

◎ Product Description

This product supports one RS-232/485/422 electrical signal as a node to connect to a pair of fiber optic rings (main ring+backup ring) for ring network transmission. It can support one master node and 1-99 slave nodes. Fiber optic ring with single and multi-mode options, default between single-mode nodesDistance020 kilometers (customizable for extra long), between multi-mode nodesDistance02 kilometers, when the ring is interrupted or a node fails, other nodes can bypass the fault point and continue to communicate with the main station through a self-healing mechanism, while simultaneously issuing alarm messages and displaying the fault location.
