How many optical fiber cables need to be connected to the ring main unit
In the optical fiber ring topology, two optical fiber cables are required. Minimum Fibre Cores in the fibre cable between any two buildings: Each switch connects back to the core of the network with 4 fibre cores (2 running clockwise, 2 running anti-clockwise). This circular arrangement creates a highly efficient, high-capacity network architecture with several notable advantages. My engineer is saying that this won't work, that there is a limit of approximately 17 devices in the ring.
