Self-Healing Ring Topology with Fiber Optic Repeater
This configuration can be achieved by connecting the unused fiber optic ports of the
first and last 140NRP95400 directly or through the fiber optic repeater. This type of
connection has all the advantages of the previously described configurations, along
with built-in redundancy. A broken connection between any two Quantum NRP
modules in the ring will automatically reconfigure the RIO network and continue the
communication.
NOTE: The maximum length of the fiber cable in a ring configuration, 16 km, is
calculated in the the case of a break that occurs anywhere.
