Abstract
The invention provides a hermetic fiber-optic seal, such as in an optical fiber ferrule or feedthrough, having an optical fiber, a glass solder for encasing at least a portion of the optical fiber, a first glass sleeve for encasing at least a first portion of the glass solder, a second glass sleeve for encasing at least a second portion of the glass solder, and an outer sleeve for encasing at least a portion of the first glass sleeve and the second glass sleeve. A gap filled with glass solder may be provided between the first glass sleeve and the second glass sleeve. The hermetic fiber-optic seal is made by an extrusion process.
