Engineering:Hydroxyl ion absorption
From HandWiki
Short description: Transmission loss in optical fibers
Hydroxyl ion absorption is the absorption in optical fibers of electromagnetic radiation, including the near-infrared, due to the presence of trapped hydroxyl ions remaining from water as a contaminant.[1]
The hydroxyl (OH−) ion can penetrate glass during or after product fabrication, resulting in significant attenuation of discrete optical wavelengths, e.g., centred at 1.383 μm, used for communications via optical fibres.[2]
