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. I am planning to connect core switch to multiple switches using 6 strand fiber cable. which type of cnnection is resilient Star or Ring??? If I make star then do i have to use new cable to each switch or strand of a cable to patch other switch??Thanks. It usually depends on the model of the switches. The Cisco Catalyst 9500 Series Switches family consists of fixed core and aggregation layer switches supporting redundant power supplies and modular fans. Fiber provides: Increased internet signal bandwidth. Most modern fiber-enabled network switches require an SFP transceiver module. Other than entry level network switches, most of today's network switches include one or more GiBC (Gigabit Converter) or SFP (Small Form-factor Pluggable) slots. SFP modules insert into these slots and and require two strands of fiber, typically duplex Using multi mode fiber (for runs under 1000. Fiber optic patch cords are fiber cables terminated with connectors on both ends, used to establish optical connections between devices or between devices and patch panels.
