Which of the following is true about the core of multimode fiber?

The correct answer highlights the characteristic of multimode fiber regarding its core size in comparison to single-mode fiber. Multimode fiber has a larger core diameter, which typically ranges from 50 to 62.5 micrometers, while single-mode fiber has a core diameter of approximately 8 to 10 micrometers. This larger core in multimode fiber is designed to allow multiple modes of light to propagate simultaneously, enabling the transmission of more data over shorter distances.

The larger core size facilitates easier connection and alignment due to its increased acceptance angle, which can mitigate challenges associated with the light paths in fiber optics. This is particularly advantageous in environments where beam divergence is prevalent.

Understanding these core differences is essential for designing and implementing efficient fiber optic systems, especially when selecting the appropriate type of fiber for specific applications. It’s critical for professionals in the field to know how these physical characteristics impact performance and installation methods.
