The Weed Instrument Self-Healing Ring Module (SHR) provides fiber media redundancy when utilized in each node or drop of a fiber optic ring network. Data will always be routed on the shortest possible path to reduce propagation delay through the system. The SHR accomplishes this by creating a “virtual” break in the ring at the link farthest from the originating node.
In the above illustration, if Node 1 is the originating node of a message, a virtual break will be created on the fiber link B or C (B is shown here). This virtual break is created on a packet by packet basis. Therefore, the network behaves as if it were in a Daisy Chain, preventing the delivery of the same packet to any node twice.
