A multimode graded index fibre exhibits total pulse broadening of 0.1 us cover a distance of 1.5km. What is the maximum possible band width on the link assuming no inter symbol interference?

A

10MHz

B

7.5M Hz

C

5MHz

D

2.5MHz

Text Solution

Verified by Experts

The correct Answer is:
C
The maximum possible optical band width is equivalent to the maximum possible bit rate (for return to zero pulses). It is given by
`B_(T)=(1)/(2tau)=(1)/(2xx0.1xx10^(-6))=5MHz`
