Question

Which one of the following is false with respect to fiber optic cables?

(a) High speed

(b) Heavy compared to normal wires

(c) Less EM interference

(d) Costly

This question was posed to me by my school teacher while I was bunking the class.

Origin of the question is Fly-by-Light Flight Control topic in division Fly by Wire Flight Control of Avionics

Answer 1

Right answer is (b) Heavy compared to normal wires

Easy explanation: Fiber optics weigh comparatively very low than normal wires. Wires require shielding from EMI which also adds up to the overall weight of the connectivity system. They also offer high speed data transfer and are relatively costly.
