For most setups, cables with 12, 24, or 48 cores are common choices, ensuring compatibility with modern equipment and ease of management. If you have multiple Ethernet switches that need to be connected over long distances, fiber is obviously a preferred choice. IBDN standard suggests using 12-core cables for communication rooms within buildings and 24-core cables for main distribution rooms, which can serve as a. For the fibre optics connection, you will need an optical fibre cable (or optical patch cord) with LC connectors at the ends. Regards, Martin 10-12-2020 09:20 AM You need use right. 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. Manufacturers commonly offer cables in multiples that simplify manufacturing and management: low-count options (2, 4, 6, 12) for simple duplex or small distribution runs; medium trunk sizes (24, 48, 72) for enterprise backbones and campus links; and high-density cores (144, 288, 432, 864+) for. Whether the connections between switches are stacked is also one of the considerations. Stacking: If the core switch is dual-machine hot standby (both are working at the same time) for redundancy, 6 cores are sufficient (2 cores switch each use 2 cores, and 2 cores are redundant).
