Fiber Optic Bulkhead Feedthrough for Souriau 38999 ELIO Connectors
Engineers designing electronic components that must operate reliably in harsh environments can now leverage the increased performance of fiber optic technology, following the release of PA&E’s new hermetic fiber optic bulkhead feedthru for the Souriau ELIO 38999 fiber optic connector line. This new, lightweight interconnect solution allows engineers to take advantage of fiber optics in applications where that technology was once unworkable due to hermetic requirements. And, it delivers truly hermetic performance at a significant (up to 60%) weight savings when compared to stainless steel alternatives.
ThisGlass is the traditional sealing material for many hermetic interconnect solutions, but in fiber optic applications, a glass sealing process is impractical because the temperatures required to create a glass seal are high enough to destroy optical fiber. This innovative new interconnect solution uses PA&E’s Kryoflex® polycrystalline ceramic-to-metal sealing technology. Seals are created at much lower temperatures so fiber optics remain intact while this new feedthru achieves a leak rate ≤ 1X10-9 cc/sec He at one atmospheric differential pressure. Kryoflex seals provide a direct ceramic-to-metal bond, by means of oxygen-pinned valence bonding. This unchanging chemical and mechanical bond is enhanced by Kryoflex's randomly organized crystalline structure, which allows this unique material to relieve stresses from within itself.
