What is the typical diameter range for Multimode Fiber?

The typical diameter range for multimode fiber is between 50 and 100 micrometers (µ). Multimode fiber optics use multiple light modes or pathways to transmit data, and the core diameter is significantly larger compared to single-mode fiber, which typically has a core diameter of around 8 to 10 micrometers.

The larger core diameter of multimode fiber allows for multiple light paths, which can reduce the distance over which the signal can effectively travel due to modal dispersion, but it also allows for easier coupling with light sources such as LEDs. The specified range of 50 to 100 micrometers is standard for multimode fibers that are typically used in local area networks (LANs) and other short-distance communication applications.

In contrast, the other options provided do not accurately represent the standard diameters for multimode fiber. For instance, diameters around 1 to 2 micrometers are characteristic of single-mode fibers, which utilize a much narrower core to transmit data over longer distances with fewer modes and less dispersion. The ranges of 8.3 to 10 micrometers and 200 to 400 micrometers are also outside the standard specifications for multimode fiber, which is why the correct range of
