Abstract

A terminal for mounting to a fiber distribution cable includes a housing having a base and a cover. The cover is connectedly engaged with the base. The terminal further includes a plurality of adapters disposed on the cover. A fiber routing tray having a top panel and a bottom panel is disposed in an interior cavity. The fiber routing tray includes a storage space defined between the top and bottom panels for storing a length of optical fiber. A method for installing a terminal includes providing a terminal having a housing defining an interior cavity. A cable is pulled from the interior cavity of the housing. The cable is spliced to a fiber distribution cable with a splice. The cable is inserted back into the interior cavity. A spliced end of the cable, a spliced end of the fiber distribution cable and the splice are inserted in a retention device.

Claims

1. A terminal for mounting to a fiber distribution cable, comprising

a housing including:

a base; and

a cover connectedly engaged with the base, the cover and the base defining an interior cavity; and

a plurality of adapters adapted for outside environmental use disposed on the cover, each of the plurality of adapters including a first port for receiving a first fiber optic connector from outside the housing and a second port for receiving a second fiber optic connector from inside the housing, wherein the first ports are sealed to prevent moisture or water intrusion into the interior cavity of the housing, and wherein each of the first ports includes internal threads adapted to mate with corresponding threads of the first fiber optic connectors;

wherein the terminal has an adapter density that is greater than or equal to 0.48 adapters/in².

2. The terminal of claim 1, wherein the terminal has an adapter density that is greater than or equal to 0.57 adapters/in².

3. The terminal of claim 1, wherein the terminal has an adapter density that is greater than or equal to 0.96 adapters/in².

4. The terminal of claim 1, wherein the terminal has an adapter density that is greater than or equal to 1.14 adapters/in².

5. The terminal of claim 1, wherein the cover includes a plurality of angled steps with each angled step defining a plurality of mounting surfaces, and wherein adapters of the plurality of adapters are disposed on each of the angled steps such that one adapter is disposed on each mounting surface.

6. The terminal of claim 5, wherein the angled steps are configured on an outer surface of the cover in arcuate shaped rows.

7. The terminal of claim 5, wherein each angled step forms an oblique angle with the base and each mounting surface forms an oblique mating angle with an adjacent mounting surface on the angles step.

8. The terminal of claim 5, wherein the adapters being arcuately oriented on each of the angles steps.

9. The terminal of claim 1, wherein at least one of the plurality of adapters include an outer housing having a first end and a second end, wherein the first end is the first port having internal threads adapted to receive exterior threads of the first fiber optic connector.

10. The terminal of claim 9, wherein the outer housing of at least one of the plurality of adapters defines a sealing surface positioned inside the outer housing, the sealing surface being adapted to engage a sealing member of the first fiber

optic connector when the first fiber optic connector is inserted within the first port.
