This is the most fundamental ring topology, formed by connecting three or more switches in a closed loop using fiber optic cables. Data can flow in either direction, allowing the network to recover quickly if a link fails. If you have multiple Ethernet switches that need to be connected over long distances, fiber is obviously a preferred choice. Moreover, when it comes to bandwidth, no currently available technology is better than single-mode fiber. It can provide significantly higher bandwidth and carry more data. A single 6 strand fiber can only connect 3 switches back to the core. How many switches do you plan to connect? A star is great for a limited number of switches. I have maybe 20 coming back to my cores. Rings are generally not done anymore, but I think that is for bandwidth as much as anything else. The mainline of the fiber optic LAN directly connects to the switch, then to the router. The connection between two or more Ethernet switches in a certain way (Uplink port, etc. ) is called the cascade. All switches have two fiber ports. Is the best way to have fiber backbone switch and connect fiber channel from every switch to the backbone? Or connect switch 1 to switch 2 to switch 3 to. switch 12 to switch 1 again? Thanks! Let's get some. I need to connect 4 Floor Building with 4 Cisco 2960 - 48 ports switch each other and it needs to be through a fiber. This design ensures data can travel in both directions.
