ABSTRACT:
An optical fiber assembly having a hermetic seal portion includes a optical fiber assembly and a metal pipe. The optical fiber assembly includes a metallized portion where a portion exposed by peeling off a resin coating of the optical fiber assembly is coated with metal. The metal pipe includes a feedthrough hole, an uncovered portion, a brazed portion and an adhesive-fixed portion. The feedthrough hole has a length necessary to cover a part of the metallized portion and a part of the coated portion leading to one end of the metallized portion. The uncovered portion has a housing groove leading to the feedthrough hole and contains a remainder of the metallized portion and a part of the coated portion leading to the other end of the metallized portion. The brazed portion hermetically seals the optical fiber assembly to the metal pipe by brazing the metallized portion and the inner surface of the feedthrough hole near a slanted upward opening of the feedthrough hole on the housing groove side. The adhesive-fixed portion allows the optical fiber assembly to be disposed on the uncovered portion adhere to the metal pipe and fixed thereto.
