ii) They are less susceptible to interference by electromagnetic radiation.
iii) They are lighter and thinner than metal wires.
Options:
The correct option is C c) All of the above
C) Explanation:
Optical fibres uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
Fiber optics has several advantages over traditional metal communications lines:
-
Fiber optic cables have a much greater bandwidth than metal cables. This means that they can carry more data.
-
Fiber optic cables are less susceptible than metal cables to interference to electromagnetic radiation.
-
Fiber optic cables are much thinner and lighter than metal wires.
-
Data can be transmitted digitally (the natural form for computer data) rather than analogically.
