Hermetically sealed optical fiber feedthrough

摘要

An optical fiber feedthrough (20,24) for passing through a panel (10) and maintaining a sealed relationship between different fluid environments existing on opposite sides of the panel. A guide tube (25) secured within an opening (44) in the panel (10) by a glass seal (46). The end portions of two fibers (16, 18) to be interconnected through the panel are secured within individual termini (28,42) with the latter located within the guide tube (25) and sealed by O-rings (50,56) against fluid passage therethrough.
