Final answer:
Multimode Fiber (MMF) is characterized by multiple modes of data transmission. Unlike Single Mode Fiber (SMF), MMF allows multiple rays of light to propagate simultaneously through the fiber. MMF is commonly used in shorter distance applications due to its larger core size, which causes more dispersion and attenuates the signal over long distances.
Step-by-step explanation:
Multimode Fiber (MMF) is characterized by multiple modes of data transmission. Unlike Single Mode Fiber (SMF), MMF allows multiple rays of light to propagate simultaneously through the fiber. This is made possible because MMF has a larger core diameter, which allows for more possible light paths, resulting in a larger bandwidth capacity. MMF is commonly used in shorter distance applications due to its larger core size, which causes more dispersion and attenuates the signal over long distances.
