Which of the following are characteristics of single-mode fiber optic cable? (Choose all that apply.)
A)8-10 micron central core
B)uses a single light wave
C)transmission distance up to 2 km
D)uses LEDs for the transmission source

Question

Quizplus · Accepted Answer

Single-mode fiber optic cable has a small central core (around 8-10 microns) that allows only one mode of light to propagate, which means it uses a single light wave for transmission. This design enables it to carry signals at much higher speeds and over longer distances compared to multimode fiber optic cables. Transmission distances can significantly exceed 2 km, often reaching up to tens or even hundreds of kilometers, making option C incorrect. Single-mode fibers typically use laser sources for light transmission due to the need for a coherent light source, making option D incorrect as LEDs are more commonly used with multimode fibers.
