Abstract

There is provided fiber drop terminal (“FDT”) assemblies for providing selective connections between optical fibers of distribution cables and optical fibers of drop cables, such as in multiple dwelling units. The FDT assemblies include a base and a cover that define a tongue and groove that selectively engage to seal the base and cover. The FDT assemblies also include a mounting plate for mounting of the base and cover, as well as a mounting plate extension for mounting of a skirt. The skirt provides slack storage for drop cables exiting the FDT. The components of the FDT assembly are selectively interlockable to prevent unauthorized access to the interior cavity of the base and cover and to the slack storage area of the skirt.

Claims

1. A fiber optic terminal comprising a base and a cover, wherein the cover is selectively removable from the base to provide access to an interior cavity adapted to receive at least one fiber optic cable, the fiber optic terminal comprising:

a groove defined on at least one of the base and the cover, wherein the groove is generally defined by an inner lip and an outer lip separated by a surface; and

a tongue defined on the other of the base and the cover, wherein the tongue is adapted to be selectively sealingly engaged with at least the inner lip of the groove,

wherein the inner lip defining the groove extends from the surface a distance sufficient to enable the inner lip to deform when the tongue is selectively sealingly engaged with at least the inner lip of the groove.

2. A fiber optic terminal according to claim 1, wherein the tongue is adapted to be selectively sealingly engaged with both of the inner lip and the outer lip of the groove.

3. A fiber optic terminal according to claim 1, wherein the inner lip extends from the surface at least twice a distance as the outer lip extends from the surface.

4. A fiber optic terminal according to claim 1, wherein the groove and the tongue extend along an entire side of the fiber optic terminal.

5. A fiber optic terminal according to claim 1, wherein the base and the cover comprise an equivalent polymer material.

6. A fiber optic terminal according to claim 1, wherein at least one of the inner lip and the outer lip define an angled portion that is generally angled relative to the surface, and wherein the tongue defines a corresponding angled portion adapted to selectively sealingly engage the angled portion of the at least one of the inner lip and outer lip.
