Hydrogen loss |
Optical signal loss (attenuation) resulting from hydrogen
found in the optical fiber. Hydrogen in glass absorbs
light and turns it into heat and thus attenuates the light.
For this reason, glass manufacturers serving the fiberoptic
industry must keep water and hydrogen out of the
glass and deliver it to guaranteed specifications in this
regard. In addition, they must protect the glass with a
cladding that will preclude the absorption of water and
hydrogen into the glass.
