Step-by-step explanation:

edge

Answer 2

Answer;

A. reflectivity

Explanation;

• Cladding is the glass material surrounding the fiber core. This glass has a lower refractive index and reflects the light back into the core, thus maintaining the light level over a long distance.
• An optical coating is composed of a combination of thin film layers that create interference effects used to enhance transmission or reflection properties within an optical system.
