During fabrication of optical fibre,does annealing increases the elasticity of the optical fibre or decreases its elasticity? please explain!

Dear student

Heat treatment given to a substance is called annealing. In annealing the substance is first heated to some predetermined temperature and then slowly cooled down to room temperature.

Annealing increases the elasticity of the material ( optical fibre as asked in the question).

We hope this clarifies your doubt.
