Fibre optics is immune to.
Fibre optics is immune to.
The correct option is D Soil interference
Fibre optics is immune to Soil interference.
Immunity to electromagnetic interference: Light
transmission through optical fibers is unaffected by other electromagnetic
radiation nearby. The optical fiber is electrically non-conductive, so it does
not act as an antenna to pick up electromagnetic signals.
Magnetic field lines generate an electrical current
as they cut across conductors. ... Electromagnetic Interference does occur in
coaxial cables, since current does cut across the conductor. Fiber optics are
immune to this EMI since signals are transmitted as light instead of current.
Disadvantages of Fiber Optic Transmission. Though
fiber optic transmission brings lots of convenience, its disadvantages also
cannot be ignored. Fragility: usually optical fiber cables are made of glass,
which lends to they are more fragile than electrical wires.
A. They transmit signals in as light rather than
electric current. This is the main reason why optical fibers are immune to EMI,
which is a type of noise that originates with one of the properties of electromagnetism.
EMI is induced when magnetic field lines cut across a conductor.
