Abstract: A fiber optic cable splice enclosure is disclosed, the enclosure comprising a cannister having an open end and an expansion seal assembly for closing the open end. The seal assembly includes a plurality of cable receiving ports for admitting fiber optic cables into the enclosure. The ports are in the form of slots extending inward from the outer edges of the seal assembly. The cannister and seal assembly are constructed with an oblong-round shape which provides for increased capacity of the cannister and more seal edge area for the seal assembly, allowing for additional ports as compared to a standard, cylindrical splice enclosure.

Abstract: A cable splice closure apparatus comprising a rigid, corrosion-resistant outer structure having outer seal, for sealing about the outer structure and cables passing through the outerseal. The outer seal is formed of a pair of non-metallic end caps coupled with an inner rigid compression plate having a sandwiched elastomeric compression member therebetween. The end caps and inner compression plate being linked by bolts which when tightened urge the caps and plate together and squeeze the compressing member so as to seal about the outer structure and cables passing through the compression member. An inner splice chamber has an anchoring and sealing assembly constrained within a hoop, which anchors the cables and seals the cable entrances into the chamber. The anchoring and sealing assembly of the inner splice chamber is independent from a lid for the splice chamber which permits access to contents of splice chamber without disturbing the anchoring means.
