|
Optical fiber cable
|
|
|
Shielded twisted pair 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.
