ABSTRACT:
A cable closure (20) which is suitable for aerial, pedestal, wall-mounted or buried use and which is suitable for enclosing connections between metallic or optical fiber transmission media includes a base (30) and a cover (32). The base and/or the cover include a plurality of openings through which extend cables. Connections (50) between transmission media of the cables are disposed between portions (51,52) of a superabsorbent compliant foam material. The portions of the foam material and the base and the cover are sized so that when the cover is assembled to the base, the foam material is compressed. Upon contact with water which may enter the closure, the superabsorbent foam material swells, molding about the connections to protect them from the water and expanding outwardly to seal any unintended openings in the housing and prevent the ingress of additional water.
