Abstract

A multi-layer module that includes a multi-fiber cable storage layer having a cable entry opening and a cable winding structure is disclosed. Also included is a splice storage layer that is discrete from the multi-fiber cable storage layer, the splice storage layer having a splice layer receiving opening in communication with the multi-fiber cable storage layer and a slack storage area. The multi-layer module includes a pigtail storage layer that is discrete from both the multi-fiber cable storage layer and the splice storage layer, the pigtail storage layer having a pigtail connector area and a pigtail storage area, the pigtail storage area comprising a pigtail storage layer receiving opening in communication with the splice storage layer.

Claims

1. A multi-layer module comprising:

a multi-fiber cable storage layer having a cable winding structure;

a splice storage layer that is discrete from the multi-fiber cable storage layer, the splice storage layer having a splice layer receiving opening in communication with the multi-fiber cable storage layer, and a slack storage area having a splice holder seat with a footprint area for removably securing a splice holder; and

a pigtail storage layer that is discrete from both the multi-fiber cable storage layer and the splice storage layer having a pigtail connector area and a pigtail storage area, the pigtail storage layer comprising a pigtail storage layer receiving opening in communication with the splice storage layer,

wherein the multi-fiber cable storage layer, the splice storage layer, and the pigtail storage layer are layered such that a portion of the pigtail storage area of the pigtail storage layer is disposed in an intervening space between the multi-fiber cable storage layer and the splice storage layer, while a portion of the pigtail connector area of the pigtail storage layer is disposed outside of the intervening space between the multi-fiber cable storage layer and the splice storage layer.

2. The multi-layer module of claim 1, further comprising an adapter plate positioned in an adapter opening and removably connected to the multi-layer module.

3. The multi-layer module, of claim 1, further comprising a hinged cover having a closed position and an open position, wherein in the closed position, the hinged cover covers at least a portion of the splice storage layer, and in the open position the hinged cover provides access to at least a portion of the splice storage layer.

4. The multi-layer module of claim 3, further comprising a hinged separator having a closed position and an open position, wherein in the closed position, the hinged separator separates the splice storage layer from the pigtail storage layer and in the open position the hinged separator provides access to the pigtail storage layer.

5. The multi-layer module of claim 4, wherein the hinged cover and the hinged separator define opposing hinges and overlapping access fields in the multi-layer module.

6. The multi-layer module of claim 4, wherein the hinged cover and the hinged separator are configured relative to each other such that the hinged cover is transitioned from the closed position to the open position to permit the hinged separator to be transitioned from the closed position to the open position.

7. A multi-layer module comprising:

a multi-fiber cable storage layer having a cable entry opening and a cable winding structure;

a splice storage layer that is discrete from the multi-fiber cable storage layer, the splice storage layer comprising a slack storage area and a splice holder, the slack storage area having a splice holder seat with a footprint area for removably securing the splice holder; and

a pigtail storage layer that is discrete from both the multi-fiber cable storage layer and the splice storage layer, the pigtail storage layer comprising a pigtail storage area and pigtail connector area, the pigtail storage area in communication with the splice storage layer,

wherein the multi-fiber cable storage layer, the splice storage layer, and the pigtail storage layer are layered such that a portion of the pigtail storage area of the pigtail storage layer is disposed in an intervening space between the multi-fiber cable storage layer and the splice storage layer, while a portion of the pigtail connector area of the pigtail storage layer is disposed outside of the intervening space between the multi-fiber cable storage layer and the splice storage layer.
