Drag and Drop Question Drag and drop the characteristic from the left onto the cable type on the right. Answer:

The correct answer is uses multiple wavelengths of light; has increased attenuation over long distances; has a core diameter of 9 microns; uses a single wavelength of light. Multimode fiber (MMF) uses multiple wavelengths (modes) of light simultaneously and has a larger core diameter (50 or 62.5 microns), which causes modal dispersion and increased attenuation over long distances, limiting it to shorter runs. Single-mode fiber (SMF) uses a single wav

Correct arrangement

uses multiple wavelengths of light
has increased attenuation over long distances
has a core diameter of 9 microns
uses a single wavelength of light

Explanation

Multimode fiber (MMF) uses multiple wavelengths (modes) of light simultaneously and has a larger core diameter (50 or 62.5 microns), which causes modal dispersion and increased attenuation over long distances, limiting it to shorter runs. Single-mode fiber (SMF) uses a single wavelength of light and has a narrow core diameter of 9 microns, which eliminates modal dispersion and allows signals to travel much farther with minimal attenuation. The correct arrangement maps 'uses multiple wavelengths of light' and 'has increased attenuation over long distances' to Multimode fiber, while 'has a core diameter of 9 microns' and 'uses a single wavelength of light' map to Single-mode fiber.
