 DIFFERENCES BETWEEN STEP INDEX AND GRADED INDEX OPTICAL FIBRE

i. Step index fibre

1. It is of reflective type.

2. In this fibre, signal distortion is high.

3. Refractive of the core is constant.

4. Numerical aperture is more for multimode step-index fiber.

ii. Graded index fibre

1. It is of a refractive type.

2. In this type fibre, signal distortion is very low

3. Refractive index of the core decreases parabolically.

4. Numerical aperture is less
