What are the different types of optical fibers used for communications transmission connections?
There actually many specific types of optical fibers that have been developed over the years. However, there are three main types of optical fiber used today for standard communications applications. There are two (2) multimode fibers (MMF): used for relatively short links (< 1.6 miles) or low data rate transmission typically < 1 gigabits per second a. 50/125 micron b.
