Final answer:
Multimode optical fiber is a type of fiber optic cable that allows for the transmission of multiple light rays simultaneously. It is suitable for short-distance communication applications, such as local area networks (LANs).
Step-by-step explanation:
Multimode optical fiber is typically referred to as a type of fiber optic cable that allows for the transmission of multiple light rays simultaneously. The core of the multimode fiber is larger in diameter, allowing for multiple paths or modes of light to travel through it. This makes it suitable for short-distance communication applications, such as local area networks (LANs). One example of multimode optical fiber is the graded-index fiber, which has a varying refractive index to minimize dispersion.
