OPTICAL WAVEGUIDE FEEDTHROUGH ASSEMBLY

摘要

An optical fiber feedthrough assembly includes a glass plug disposed in a
recess of a feedthrough housing. The glass plug may define a large-diameter,
cane-based, waveguide sealed within the recess in the housing and providing
optical communication through the housing. Sealing occurs with respect to the
housing at or around the glass plug of an optical waveguide element passing
through the housing by braze sealing to the glass plug and/or embedding the
glass
plug in a polymer bonded with the plug to form a molded body that is sealed in
the
housing by, for example, compression mounting of the molded body or providing
a
sealing element around the molded body.
