Detailed explanation-1: -Explanation: Multimode fiber has a shorter distance limitation than single mode fiber . Commonly used on LANs within a campus network.
Detailed explanation-2: -There are four different types of multimode fiber. Today’s laser-optimized OM2, OM3, and OM4 are the preferred fibers when using multimode. OM1 is traditionally an older technology that is rarely supported in today’s applications. Some older OM2 was even designed for LED-based transmission.
Detailed explanation-3: -There are three types of fiber optic cable: single mode, multimode and plastic optical fiber (POF).
Detailed explanation-4: -As mentioned earlier, there are 5 commonly used multimode fiber types used in most industries worldwide. The most common optical multimode fiber types are OM1, OM2, OM3, OM4, and OM5.
