Lonworks multi-drop self-healing ring fiber optic modem
Introduction
The multi-drop self-healing ring fiber optic modem interlinks with Lonworks interface devices over a pair of optical fiber cables. This product is intended for self-healing ring topologies. Our multiple self-healing ring configuration offers maximum reliability as it can recover simultaneous faults or failures in two different locations. The self-healing ring consisits of two data paths, Ring A and Ring B, with each data path running in an opposite direction to the other. Under normal operation, only the primary data patch (Ring A) is used, when there is a fault (cable or failed device), the data path will turn around before it reaches the fault or failed unit and use the secondly data path (Ring B) to complete the link. With this process, the data path remains intact. The data communication protocol is transparent and compatible with all the Lonworks upper protocols.
The multi-drop self-healing ring fiber optic modem can be widely used, such as industrial controls, intelligent transportation systems (ITS), industrial networking, supervisory control and data (SCADA) and so on.
