Hydroxyl Ion Absorption
The absorption of electromagnetic waves, including the near infrared, due to the presence of trapped hydroxyl ions remaining from water as a contaminant. The hydroxyl (OH-) ION can penetrate glass during or after product fabrication, resulting in significant attenuation of discrete optical wavelengths used for communications via optical fibers.
