There are four commonly used OM (multimode) fibers: OM1, OM2, OM3 and OM4. Each type of them has different characteristics. The article will compare these four kinds of fibers from history,the side of core size, bandwidth, data rate, distance, color and optical source in details.
1.What is singlemode and multimode fiber? What is the difference between them? The concept of single-mode and multi-mode is to
Optical fiber is the backbone of modern communications. Singlemode fiber dominates long distance applications because of its reliability; however,This fiber has an internal diameter of only 10 micrometers (us) and is very expensive.
