Abstract

A fiber optic adapter assembly reduced in size from a SFP footprint to a SC footprint to accommodate a first fiber optic connector on a first side within one or more ports, and a second fiber optic connector on a second side within one or more ports. The first fiber optic connector is a duplex fiber optic connector with an overall length of about 50 mm and the second fiber optic connector is a behind-the-wall connector with an overall length of about 15 mm thereby reducing the overall length of a connector and adapter assembly for increasing optical fiber density.

First claim

What is claimed is:

1. A fiber optic port device, the fiber optic port device comprising:
a housing comprising:
a first side wall, a second side wall, and a width extending from the first side wall to the second side wall,
a first end wall, a second end wall, and a height extending from the first end wall to the second end wall,
a middle wall extending from the first end wall to the second end wall, the middle wall being spaced apart between the first side wall and the second side wall of the outer housing,
wherein the first side wall, the middle wall, the first end wall, and the second end wall define a first generally rectangular receptacle having first and second duplex connector ports spaced apart along the height,
wherein the middle wall, the second wall, the first end wall, and the second end wall define a second generally rectangular receptacle having third and fourth duplex connector ports spaced apart along the height;

a first pair of ferrule alignment sleeves received in the first duplex connector port;
a second pair of ferrule alignment sleeves received in the second duplex connector port;
a third pair of ferrule alignment sleeves received in the third duplex connector port; and
a fourth pair of ferrule alignment sleeves received in the fourth duplex connector port,
wherein each pair of ferrule alignment sleeves comprises first and second ferrule alignment sleeves spaced apart along the width of the housing.

2. The fiber optic port device of claim 1 , wherein each of the first and second generally rectangular receptacles is non-partitioned such that each of the first and second generally rectangular receptacles is free of internal widthwise walls separating the duplex connector ports.

3. The fiber optic port device of claim 2 , wherein the middle wall has a second side facing the second generally rectangular receptacle, the second side shaped with first features for aligning a first plurality of duplex connectors with the first plurality of duplex connector ports.

4. The fiber optic port device of claim 1 , wherein the middle wall has a first side facing the first generally rectangular receptacle, the first side shaped with first features for aligning a first plurality of duplex connectors with the first plurality of duplex connector ports.

5. The fiber port device as set forth in claim 4 , wherein the first features define a first plurality of alignment channels spaced apart along the connector height and wherein second features define a second plurality of alignment channels spaced apart along the connector height,
wherein the first plurality of alignment channels is configured to slidably receive correspondingly sized and shaped portions of the first plurality of duplex connectors to align the first plurality of duplex connectors with the first plurality of duplex connector ports; and
wherein the second plurality of alignment channels is configured to slidably receive correspondingly sized and shaped portions of the second plurality of duplex connectors to align the second plurality of duplex connectors with the second plurality of duplex connector ports.

6. The fiber optic port device as set forth in claim 1 , wherein the height is 9.5 mm.

7. The fiber optic port device as set forth in claim 6 , wherein the width is 25.8 mm.

8. The fiber optic port device as set forth in claim 1 , wherein the width is 25.8 mm.

9. The fiber optic port device as set forth in claim 1 , wherein the housing is configured to fit four duplex connectors in a duplex-SC adapter footprint.

10. The fiber optic port device as set forth in claim 1 , further comprising a pair of opposing adapter latch hooks in each of the first, second, third, and fourth duplex connector ports.

11. The fiber optic port device as set forth in claim 10 , wherein each pair of opposing adapter latch hooks comprises a first adapter latch hook and a second adapter latch hook on opposite sides of the respective one of the first, second, third, and fourth duplex connector ports, and wherein each first adapter latch hook is configured to latch with a first side of a duplex connector port mated in the respective one of the first, second, third, and fourth duplex connector port and each second adapter latch hook is configured to latch with is configured to latch with a second side of the duplex connector port mated in the respective one of the first, second, third, and fourth duplex connector port.

12. A fiber optic port device, the fiber optic port device comprising:
a housing comprising:
a first side wall, a second side wall, and a width extending from the first side wall to the second side wall,
a first end wall, a second end wall, and a height extending from the first end wall to the second end wall, and
a middle wall extending from the first end wall to the second end wall, the middle wall being spaced apart between the first side wall and the second side wall of the outer housing,
the housing defining first and second duplex connector ports between the first end wall and the middle wall and second and third duplex connector ports between the second end wall and the middle wall;
the middle wall having a first side facing the first and second duplex connector ports and a second side facing the third and fourth duplex connector ports;

wherein the first end wall defines a first groove aligned with the first duplex connector port and a second groove aligned with the second duplex connector port, the first groove and the second groove each having a first heightwise dimension;
wherein the first side of the middle wall defines a third groove aligned with the first duplex connector port and a fourth groove aligned with the third duplex connector port, the third groove and the fourth groove having a second heightwise;
wherein the second end wall defines a fifth groove aligned with the third duplex connector port and a sixth groove aligned with the fourth duplex connector port, the fifth groove and the sixth groove each having the second heightwise dimension;
wherein the second side of the middle wall defines a seventh groove aligned with the third duplex connector port and an eighth groove aligned with the fourth duplex connector port, the seventh groove and the eighth groove having the first heightwise dimension less than the first heightwise dimension;
wherein the second heightwise dimension is less than the first heightwise dimension.

13. The fiber optic port device as set forth in claim 12 , wherein the height is 9.5 mm.

14. The fiber optic port device as set forth in claim 13 , wherein the width is 25.8 mm.

15. The fiber optic port device as set forth in claim 12 , wherein the width is 25.8 mm.

16. The fiber optic port device as set forth in claim 12 , wherein the housing is configured to fit four duplex connectors in a duplex-SC adapter footprint.

17. The fiber optic port device as set forth in claim 12 , further comprising a pair of opposing adapter latch hooks in each of the first, second, third, and fourth duplex connector ports.

18. The fiber optic port device as set forth in claim 17 , wherein each pair of opposing adapter latch hooks comprises a first adapter latch hook and a second adapter latch hook on opposite sides of the respective one of the first, second, third, and fourth duplex connector ports, and wherein each first adapter latch hook is configured to latch with a first side of a duplex connector port mated in the respective one of the first, second, third, and fourth duplex connector port and each second adapter latch hook is configured to latch with is confi
