Computers - General Knowledge Questions
Optic fibres are used in place of wire cables because
they are more economical
they do not require boosting
they generate strong magnetic fields
they do not generate magnetic fields

Correct Answer : Option (D) - they do not generate magnetic fields

Optical fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Besides, there are no radiated magnetic fields around optical fibers; the electromagnetic fields are confined within the fiber. Since fiber optics do not radiate electromagnetic energy, emissions cannot be intercepted.
