There are 2 basic sorts of fiber optics, solitary-method optical fiber (SMF) and multi-mode optical fiber (MMF). One-manner fiber has the advantage of having the ability to sustain a coherent sign for dozens and even 100 kilometers. Multimode fiber is less expensive to terminate but is restricted to a couple of hundred or simply only a few dozens of meters, based on the facts price and cable quality.[54]
