Question

Explain fiber bending losses and its types in optical fiber

Answer 1

Answer:

Explanation:

Bending losses

 The loss which exists when an optical fiber undergoes bending is called bending losses.

 There are two types of bending

i) Macroscopic bending Bending in which complete fiber undergoes bends which causes certain modes not to be reflected and therefore causes loss to the cladding

ii)Microscopic bending: Either the core or cladding undergoes slight bends at its surface. It causes light to be reflected at angles when there is no further reflection
