Hydroxyl Ion Absorption

We specialise in the termination of optical fibres, connectors and devices across diverse sectors, medical, aerospace, sensor, telecommunications, defence and more.

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.
