Question

which of the following allows the telecommunications industry to transmit the greatest volume of data at the fastest speed? a copper wire b optical fiber c wireless router d aluminum wire

Explanation:

Optical fiber uses light signals to transmit data. Light has a very high frequency and can carry a large amount of information. Also, the attenuation (loss of signal strength) in optical fiber is much lower compared to copper or aluminum wires over long distances. Wireless routers have limitations in terms of speed and volume due to interference, range, and the nature of wireless signal propagation (using radio waves which have lower frequency compared to the light used in optical fibers for data - carrying capacity in telecommunications). So, optical fiber allows the telecommunications industry to transmit the greatest volume of data at the fastest speed.

Answer:

B. optical fiber
