Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why are fiber optic cables used for long distances on the Internet Backbone, such as across country and under the ocean.
A
Because they are heavyweight cables
B
Because they are extremely durable
C
Because they carry data the fastest
D
Because they are the least expensive
Explanation: 

Detailed explanation-1: -Fiber optic cables are able to transmit data faster than copper cables because they use light instead of electrical pulses to carry data from one point to another. This light is able to travel a lot further and a lot faster than copper cables in a much shorter amount of time.

Detailed explanation-2: -Fiber Optic Backbone Cable Benefits Because of its ability to carry more data than copper, fiber optic cable is frequently used to link switches between telecommunications rooms. In this capacity it acts as a data backbone between rooms. Fiber is also commonly used for longer runs.

Detailed explanation-3: -Here’s the important thing to remember: fibre optic transmits data as light, while copper delivers information as electricity. As light travels exponentially faster than electricity, reason suggests that data will travel faster via fibre optic cables than it would through copper.
