Question

What is the fastest mode of data communication between components in aircraft?

(a) Coaxial cable

(b) Twisted pair cable

(c) Fiber optic cable

(d) Radio communication

I had been asked this question in an international level competition.

I need to ask this question from Data Bus Systems topic in portion Avionics System Integration of Avionics

Answer 1

Right answer is (c) Fiber optic cable

Easy explanation: A single screened twisted pair of wires only is required with such an encoding system to transmit information data rates of up to 1 to 2 Mbits/s. Higher data rates of up to 100 Mbits/s can be transmitted using a suitably screened coaxial electrical cable and information at even higher data rates can be transmitted as coded light pulses using a fibre optic cable. Radio communication is not for data transfer between aircraft components.
