Choose a CORRECT statement on the optical fiber.
A) The multi-mode fiber has lower attenuation than the single-mode fiber.
B) The single mode fiber should have a larger core than the multi-mode fiber.
C) The multi-mode fiber has a longer transmission distance than the single-mode fiber.
D) Transmitting multiple light signals concurrently in a single-mode fiber is not possible with current technology.
E) The single-mode fiber is a preferred choice in laying WAN backbone links.

Question

Quizplus · Accepted Answer

The single-mode fiber has a smaller core, which allows for higher bandwidth and longer transmission distances without signal distortion. Therefore, it is the preferred choice in laying WAN backbone links. Options A, B, and C are incorrect as they state the opposite of the correct statement. Option D is also incorrect as transmitting multiple light signals concurrently is possible with current technology using wavelength division multiplexing (WDM) techniques.
