Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Fiber optic cables transfer data at the speed of light, so they have the ____ latency. This results in the ____ connection.
A
lowest, slowest
B
lowest, fastest
C
highest, slowest
D
highest, fastest
Explanation: 

Detailed explanation-1: -Because light travels approximately 1.5 times slower through optical fiber than in a vacuum, the latency is 5 µsec per kilometer. The number 1.5 is referred to as the Index of Refraction and will vary slightly based on the wavelength of light being propagated and composition of the optical fiber.

Detailed explanation-2: -Fibre optic: up to 10Gbps (at a data transfer rate of up to 10 billion bits per second) Copper cable: 25-300 Mbps (at a data transfer rate of up to 300 million bits per second) DSL: 0.5-75 Mbps.
