How to choose core amount when Monitoring project

The amount of cores is the amount of glass fibers contained in each fiber. We will  introduce some of the methods to determine the number of fiber cores.
First of all, know the number of layers of wiring points, calculate the number of switches, switches are stacked between the stack or not. If the stack, the core switch for the double-hot redundancy, then the 6-core enough (2 cores each with 2 core, 2 core redundancy). If you do not stack a switch to 4 core, the number of switches multiplied by 4 plus 4 core redundancy, it can be. (Note: Redundancy: as long as more than the use of more redundant is called the main equipment: one, the other exactly the same spare;
Backup: both are in working state; Cold backup: The backup device is in the standby state. )
Experience: each floor wiring closet (horizontal wiring cabinet), set up a fiber, generally six core: two core use, two core spare, two core redundancy; also use eight core fiber. The minimum specification is 2 cores per 48 points. Of course, 48-point optional 4-core, because the two cores for the smallest unit of fiber, leaving more than two cores as a backup more appropriate.
These are the number of fiber optic cable to determine the method described, we can look at. Backup can be due to people and should be selected, so the fiber out of the core number of different, according to the specification only to ensure a minimum selection plus a backup core number on it.
