A 6 strand fiber will give you usable 3 lines (1 Send and 1 Receive), 12 will give you 6 usable. So you will need a 12 strand if you want redundancy. Thanks for your quick response. We are adding new switches in stack on some floors in stack (pair of 2) and need to connect 2 trunks using port channel to our core switches in stack (pair of 2) using fiber cable. I need to know how many Fiber cables is required or if 1 Fiber with 6 or 12 strand is enough to have 2 trunk link. First, have a clear understanding of the number of layer cabling points, count the number of switches, and whether the connections between switches are stacked. The specific operations are as follows: 1. If the core switches are stacked for dual-system hot backup redundancy, 6 cores are sufficient. These locations are where all switches, hubs and any other networking equipment will be located. Single family homes, apartments, condominiums and other multi-dwelling units are increasingly wired with fiber optic cable to future-proof installations and create more reliable, higher-bandwidth and faster speed network and video infrastructures. In larger projects, fiber-based systems also easily.
