What is the core diameter range for multi-mode fiber optics?

The core diameter range for multi-mode fiber optics typically spans from 50 to 62.5 micrometers. Multi-mode fibers are designed to carry multiple light modes or rays simultaneously, making them suitable for short-distance communication applications. The larger core diameter in multi-mode fibers allows for the accommodation of multiple light paths, which is essential for their intended function in local area networks (LANs) and data centers.

The 50-micrometer core is commonly used for laser-based light sources, providing higher bandwidth capabilities, while the 62.5-micrometer core was once prevalent in older installations that relied on incandescent light sources. This diameter range facilitates light propagation in multiple modes, impacting both the fiber’s bandwidth and the distance it can effectively transmit data.

The other options either refer to single-mode fibers or fall outside the standard specifications recognized for multi-mode fiber optics, reinforcing the importance of understanding these specifications for proper installations and applications.
