Abstract: An optical connection terminal includes a first connection module and a second connection module that each terminate multi-fiber cables. The second connection module operatively couples to the first connection module so that at least one of the optical connectors of the first connection module directly optically couples with one of the optical connectors of the second connection module. A connection between the at least one optical connector of the first connection module and the optical connector of the second connection module is sealed from an exterior of the terminal.

Abstract: Aspects and techniques of the present disclosure relate to a cable sealing structure comprising a cable sealing body including a gel and methods of making anisotropic behavior in cable sealing structures made with a dry silicone gel. In one aspect, various three-dimensional printing techniques are used to make a cable sealing structure that includes a gel. The cable sealing body has a construction that elastically deforms to apply an elastic spring load to the gel. The cable sealing body has a construction with anisotropic deformation characteristics that allows the cable sealing body to be less deformable in one direction than in others. The cable sealing structure can be utilized to seal fiber optic cables more uniformly while limiting the potential of leakage.
