Correct answer: C. 100 km
- A. 300 km
- B. 200 km
- C. 100 km
- D. 20 km
Explanation
In optical fiber transmission systems, repeaters are used to amplify and regenerate the optical signals. In newer systems, repeaters are typically separated by distances of around 100 km.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
