Nimewo a nan nwayo fib refere a kantite fib vè nan chak fib. Chwa a nan kantite nwayo detèmine pa demann. Premyèman, ou dwe konprann kantite pwen fil elektrik, kalkile kantite switch, epi si koneksyon ki genyen ant switch yo anpile oswa ou pa anpile. Si se yon pil, switch debaz la se doub-sistèm cho- sibstiti redondans, ak 6 nwayo yo ase. Si ou pa pile, yon switch bezwen 4 nwayo, epi kantite switch yo miltipliye pa 4 plis èkse 4 nwayo.
Each floor wiring closet (horizontal wiring cabinet) is equipped with an optical fiber, generally six cores: two cores are used, two cores are spare, and two cores are redundant; there are also eight cores of optical fiber. The standard minimum configuration is 2 cores per 48 points.
