Abstract
A water proof and air tight fiber cable splice enclosure assembly includes a pair of housing members that are selectively releasably and sealingly clamped to each other to define a first storage volume and at least one keyhole slot connection area cooperative with an associated tie-down strap for connecting an optical fiber bundle to one of the first or second housing members. A set of arcuate wall members are formed on one of the housing members for defining an oval-shaped buffer cable storage space within the housing and an annular auxiliary cable storage space for storing an auxiliary length of the optical fiber bundle. An air valve is provided on one of the housing members for directing a flow of air into the storage space of the optical fiber splice case. The air valve is adapted to meter the flow of air into the space to below a predetermined threshold air flow rate. A pressure relief vent is provided on the enclosure to regulate air pressure accumulated within the storage volume to a pressure less than a predetermined maximum pressure threshold.
