Material Notes:

Material Description: A single component, B-stageable, optical grade epoxy for fiber optic assembly. It may be used for B-stage sealing of fiber cables into ferrules, or fiber optic feed through into the opto-package. B-stage adhesive joining of glass or optics can also be realized.Information Provided by Epoxy Technology
