Discussion
Which transmission media has the highest transmission speed in a network?
Answer: C
Correct answer: optical fiber
Optical fibre carries data as light through a glass core and offers by far the greatest bandwidth of the guided media, with speeds in the gigabits and terabits per second and very low attenuation over long distances. It is also immune to electromagnetic interference and hard to tap. Twisted pair and coaxial cable both carry electrical signals and are limited by attenuation and interference well below what fibre achieves.
