Which risk during optical fiber manufacturing escalates under elevated temperature?

💡 Explanation

Hydroxyl ion absorption increases with temperature because thermally activated diffusion introduces OH- ions into the fiber matrix causing light attenuation via vibrational absorption; therefore signal loss rises rather than maintaining refractive index or scattering efficiencies, which may exhibit other temperature dependencies.
