Anna University Regulation 2017 (ECE) 7th SEM EC8751 OC- Optical Communication question paper

1.Mention attenuation constant of a fiber.
2.Recall numerical aperture of a step index fiber.
3.Define critical angle.
4.What is total internal reflection in a fiber?
5.State Snell’s law.
6.Describe linearly polarized mode?
7.Illustrate the necessity of cladding for an optical fiber.
8.Relate the mode-field diameter and spot size.
9.Outline any four advantages of an optical communication system.
10.Demonstrate Conical Half angle?
11.Relate a formula for the normalized frequency and NA. Hence, find the Numerical aperture for a step index fiber that has normalized frequency V=26.6 at a 1300nm wavelength and core radius of 25μm.
12.Apply the ray transmission theory to find the critical incident angle for a glass rod of refractive index 1.5, surrounded by air.

13.With the knowledge of the total internal reflection, calculate the critical angle of incidence between two substances with different refractive indices where n1 = 1.5 and n2 = 1.46.
14.Why partial reflection does not suffice the propagation of light?
15.Categorize out the advantages of the multimode fiber.
16.Distinguish Step index fibers and graded index fiber.
17.Evaluate the critical angle with the relative refractive index difference of 1% for an optical fiber. Given the core refractive index is 1.46.
18.Determine the cutoff wavelength of a single mode fiber with core radius of 4μm and Δ = 0.003.
19.A graded index optical fiber has a core with a parabolic index profile which has a diameter of 50μm.the fiber has a numerical aperture of 0.2. Calculate the total number of guided modes in the fiber when its operating at a wavelength of 1μm.
20.Formulate the normalized frequency at 820 nm for a step index fiber having a 25μm radius. The refractive indexes of the cladding and the core are 1.45 and 1.47 respectively. Find the number of modes that propagate in this fiber at 820 nm?
