Abstract

A device may include a frame, an optical connector coupled to an external surface of the frame, and an optical fiber comprising a bent section positioned external to an interior of the frame and connected to the optical connector.

First claim

The invention claimed is:

1. A device comprising:
a frame comprising an external bottom surface, the external bottom surface facing a printed circuit board (PCB) when the frame is inserted into a receptacle placed on the PCB;
an optical connector coupled to the external bottom surface of the frame, the optical connector being disposed below the external bottom surface of the frame; and
an optical fiber connected to the optical connector, the optical fiber comprising a bent section positioned external to an interior of the frame.

2. The device of claim 1 , comprising an electrical connector positioned at an end of the frame.

3. The device of claim 2 , wherein the optical connector is offset with respect to the electrical connector in a longitudinal direction of the frame.

4. The device of claim 1 , comprising a cover coupled to the frame and accommodating at least a portion of the bent section of the optical fiber.

5. The device of claim 4 , wherein the cover is optically sealed with respect to the frame.

6. A form factor device comprising:
a frame having a first end, a second end and an external bottom surface, the external bottom surface facing a printed circuit board (PCB) when the frame is inserted into a receptacle placed on the PCB;
a first connector positioned at the first end of the frame;
a second connector coupled to the external bottom surface of the frame, the second connector being disposed below the external bottom surface of the frame, the second connector being offset from the first end towards the second end of the frame in a longitudinal direction.

7. The form factor device of claim 6 , wherein the first connector is an electrical connector.

8. The form factor device of claim 6 , wherein the second connector is an optical connector.

9. The form factor device of claim 6 , comprising an optical fiber connected to the second connector, the optical fiber comprising a curved section positioned external to an interior of the frame.

10. The form factor device of claim 9 , comprising a shell coupled to the frame and accommodating at least a portion of the curved section of the optical fiber.

11. The form factor device of claim 10 , wherein the shell is optically sealed with respect to the frame.

12. A data communication system comprising:
a form factor device comprising:
a frame having a first end, a second end and an external bottom surface, the external bottom surface facing a printed circuit board (PCB) when the frame is inserted into a receptacle placed on the PCB;
a first connector positioned at the first end of the frame; and
a second connector coupled to the external bottom surface of the frame the second connector being disposed below the external bottom surface of the frame; and

a network switch device comprising:
a front panel, the front panel comprising:
a first receptacle opening to receive the first connector of the form factor; and
a second receptacle opening to receive the second connector of the form factor;

a printed circuit board (PCB) placed behind the front panel;
a first receptacle placed on the PCB, the first receptacle to receive the first connector of the form factor device through the first receptacle opening; and
a second receptacle placed on the PCB on opposing side of the PCB relative to the first receptacle, the second receptacle to receive the second connector of the form factor device.

13. The data communication system of claim 12 , wherein the second connector of the form factor device is offset with respect to the first connector of the form factor device in a longitudinal direction of the frame of the form factor device.

14. The data communication system of claim 12 , wherein the first connector of the form factor device is an electrical connector.

15. The data communication system of claim 12 , wherein the second connector of the form factor device is an optical connector.

16. The data communication system of claim 12 , wherein the form factor device comprises an optical fiber and connected to the second connector of the form factor device, the optical fiber comprising a curved section positioned external to an interior of the frame of the form factor device.

17. The data communication system of claim 16 , wherein the form factor device comprises a shell coupled to the frame of the form factor device and accommodating at least a portion of the curved section of the optical fiber of the form factor device.

18. The data communication system of claim 17 , wherein the shell of the form factor device is optically sealed with respect to the frame of the form factor device.
