METHOD OF SEALING OPTICAL FIBRE IN HOUSING Russian patent published in 2015 - IPC G02B6/46 

FIELD: instrumentation.

SUBSTANCE: method consists in the application of an anaerobic adhesive on the place of sealing of an optical fibre with the subsequent insertion of the fibre into a through hole of the part housing. After curing of the adhesive the part is loaded with gas pressure, at which it is necessary to ensure its sealing. Then, on the end surface of the part, including the location of the adhesive connection of the fibre with the housing, a new portion of the adhesive is applied, and at the side of this end the reload is applied to the part with the gas pressure, at which it is necessary to ensure its sealing.

EFFECT: increase in the ultimate pressure at which the functional capability of the sealing place of the optical fibre in the housing is maintained.
