ABSTRACT:
A fiber optic interface junction assembly in which an unsheathed end portion of a floating buffer optical fiber is held in perpendicular biased abutment with an optical interface surface by a constrained terminator for such end portion and a continuous coiled portion of the buffered fiber. The interface surface may be active, as in light transmission to the abutting fiber end, or passive, as in reflection of light backwardly into the fiber at such end, according to the particular function needed to be served by the assembly. The end of the optical fiber abutting the interface surface is made square to the fiber axis by cleaving, for efficient optical coupling with such surface, and chamber means are provided for retention of index matching fluid in encirclement of such end, for added assurance of coupling efficiency and protection against contamination by light-obstructing foreign substances that may be present in the surrounding environment.
