Expert Answer:

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.
