Abstract

Fiber distribution systems, terminals and tap boxes that provide a reconfigurable and expandable system of hardened connections. An aerial terminal may include at least one feeder port and a plurality of distribution ports, each of the at least one feeder port and the plurality of distribution ports being sealable ports configured to receive one of a duct and a connector, where the connector is configured to interface with a drop type cable. The terminal may include an expandable module configured to receive a splitter. The terminal may be configured to receive a fiber through the feeder port and to output a plurality of fibers through the plurality of distribution ports.

Claims (30)

1. A fiber distribution system, comprising:

a terminal having at least one feeder port and a plurality of distribution ports, each of the at least one feeder port and the plurality of distribution ports being sealable ports configured to receive a connector having an interior cavity and a hole in communication with the interior cavity to deliver epoxy to the interior cavity so as to provide a hardened connector and to hold a fiber optic cable passing through the connector into position within the interior cavity by the epoxy, the terminal further comprising:

a case comprising a first case component and a second case component, each of the first case component and the second case component defining an exterior of the terminal and being configured to couple together to define an enclosure having a first end and a second end positioned on opposite sides of the enclosure, and a divider separating the enclosure such that the first case component defines a first retention space and the second case component defines a second retention space, each of the first retention space and the second retention space extending from the first end to the second end;

at least one fiber splice tray in the first retention space; and

an expandable module configured to receive a splitter in the second retention space,

wherein the at least one feeder port is located on the first end;

wherein the terminal is configured to be mounted aerially; and

wherein the terminal is configured to receive a fiber through the feeder port and to output a plurality of fibers through the plurality of distribution ports.

2. The fiber distribution system of claim 1 , wherein the module is configured to be replaceable and the terminal is configured to receive a plurality of swappable modules.

3. The fiber distribution system of claim 1 , wherein the module is configured to receive different types of splitters having different split ratios.

4. The fiber distribution system of claim 3 , wherein the module is configured to receive at least one optical component.

5. The fiber distribution system of claim 1 , wherein the sealable ports further include anti-rotation locking features.

6. The fiber distribution system of claim 1 , wherein each of the sealable ports is further configured to receive a duct.

7. The fiber distribution system of claim 6 , wherein each duct is configured to receive pushable fiber there through.

8. The fiber distribution system of claim 1 , wherein the module is configured to terminate said received fiber, the module further comprising a fiber management area.

9. The fiber distribution system of claim 1 , wherein the terminal further comprises at least one bend-radius protector.

10. The fiber distribution system of claim 1 , wherein the terminal is a first terminal acting as a secondary feed source and the fiber distribution system further comprises a second terminal configured to receive at least one fiber from the first terminal.

11. The fiber distribution system of claim 1 , further comprising a plurality of terminals arranged in a daisy chained configuration.

12. A fiber optic terminal comprising:

at least one feeder port configured to receive a fiber;

a plurality of distribution ports configured to output a plurality of fibers, each of the plurality of distribution ports being a sealed port configured to interface with a connector having an interior cavity and a hole in communication with the interior cavity to deliver epoxy to the interior cavity so as to provide a hardened connector and to hold a fiber optic cable passing through the connector into position within the interior cavity by the epoxy; and

a case comprising a first case component and a second case component, each of the first case component and the second case component defining an exterior of the terminal and being configured to couple together to define an enclosure having a first end and a second end positioned on opposite sides of the enclosure, and a divider separating the enclosure such that the first case component defines a first retention space and the second case component defines a second retention space, each of the first retention space and the second retention space extending from the first end to the second end;

at least one fiber splice tray in the first retention space; and

an expandable module configured to receive a splitter in the second retention space,

wherein the at least one feeder port is located on the first end; and

wherein the terminal is configured to be mounted aerially.

13. The fiber optic terminal of claim 12 , wherein the expandable module is configured to receive a splitter.

14. The fiber optic terminal of claim 13 , wherein the module is configured to be replaceable and the terminal is configured to receive a plurality of swappable modules.

15. The fiber optic terminal of claim 13 , wherein the module is configured to receive different types of splitters having different split ratios.

16. The fiber optic terminal of claim 12 , further comprising at least one bend -radius protector.
