Question 725 |
Which of the following transmission media works on the principle of total internal reflection?
Optical fiber cable | |
Shielded twisted pair cable | |
Unshielded twisted pair cable | |
coaxial cable |
Question 725 Explanation:
→ Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two.
→ In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties.
→ In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties.
