Answer
FALSE. Large core fiber is also called “multimode” fiber. Its larger diameter causes more light to be reflected within the core, and these reflections create longer paths (or “modes”) for the light to travel through the fiber. This causes a smearing or spreading effect on the output rise-time of the light pulse, which limits the maximum speed of light changes that the fiber will allow. Because data is usually transmitted by pulses of light, this, in essence, limits the maximum data rate of the fiber.
