Question

Describe the phenomena of signal distortion and transmission losses in step and graded index optical fibers with the suitable diagrams.

Answer 1

In fibre optics ,a optical phenomenon known as total internal reflection is used to transmit light rays. In case of the simplest form of optical fiber, light entering one end of the fiber strikes the boundary of the fiber and is reflected inward.

Answer 2

• Answer:
• Answer:This phenomenon is called the dispersion. So, in general the signals get distorted on an optical fiber because different frequency components undergo different attenuation and different delays
