Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: Optical fibre communication has immunity to corss-talk. Reason: Optical interference between fibres is zero.A) If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
B) If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
C) If Assertion is true but Reason is false
D) If both Assertion and Reason are false
Correct Answer: A
Solution :
Optical communication is a system by which we transfer the in formations over any distance from one location to other through optical range of frequency using optical fibre. The optical interference between fibres is zero. Hence, optical fibre communication has immunity to cross talk.
