What is the typical core diameter of multi-mode fiber?

• A. 30 µm or 50 µm
• B. 50 µm or 62.5 µm
• C. 2 µm or 8 µm
• D. 100 µm or 120 µm

Answer: (B)

The typical core diameter of multi-mode fiber is accurately represented by the values of 50 µm and 62.5 µm. Multi-mode fibers are designed to carry multiple light modes or rays, which can help facilitate faster data transmission over shorter distances when compared to single-mode fibers. The 62.5 µm diameter was a common standard used in older multi-mode fiber designs, and while it is still present in the industry today, the 50 µm core diameter has gained popularity due to its ability to support higher bandwidths and greater distances. This makes 50 µm fiber more versatile for modern networking applications. In contrast, other options presented do not align with standard multi-mode fiber specifications, as they either represent single-mode fibers (which require much smaller core diameters) or exceed common parameters for multi-mode applications.
