Multiple Choice

Singlemode fiber has ___ bandwidth than multimode fiber.

Explanation:
Bandwidth in optical communications is limited by dispersion. In multimode fiber, many paths exist and light travels at different speeds, causing modal dispersion that widens pulses and lowers the usable data rate over distance. Singlemode fiber confines light to a single path, so pulses stay narrow with minimal modal dispersion, allowing a much higher data rate for the same distance. Therefore, singlemode fiber has more bandwidth than multimode fiber, especially on longer links where dispersion dominates. Over very short distances, the difference may be less, but the fundamental advantage is the reduced dispersion in singlemode form.
