Abstract

An optical switch assembly includes a first member, a second member movably secured to the first member, and first and second optical cable connectors attached to the first member. The second member is movable between first and second positions relative to the first member. The optical switch assembly also includes an optical cable having opposite first and second ends. The optical cable first end is in optical communication with the first optical cable connector and the optical cable second end is attached to the second member. Movement of the second member to the second position causes the optical cable second end to be in optical communication with the second optical cable connector such that an optical path is established between the first and second optical cable connectors. The establishment of an optical path allows the optical cable to pass an optical signal back to a monitoring station.

First claim

That which is claimed is:

1. An optical switch assembly, comprising:
a first member;
a second member movably secured to the first member and movable between first and second positions relative to the first member;
first and second optical cable connectors attached to the first member; and
an optical cable having opposite first and second ends, wherein the optical cable first end is in optical communication with the first optical cable connector, wherein the optical cable second end is attached to the second member, and wherein movement of the second member to the second position causes the optical cable second end to be in optical communication with the second optical cable connector such that an optical path is established between the first and second optical cable connectors.

2. The optical switch assembly of claim 1 , further comprising a biasing member that is configured to urge the second member to one of the first or second positions.

3. The optical switch assembly of claim 1 , wherein the first member is pivotably secured to the second member.

4. The optical switch assembly of claim 1 , wherein the first member is configured to be secured to a door, and wherein movement of the door causes the second member to move from the first position to the second position.

5. The optical switch assembly of claim 4 , wherein the door is a door of an electronic equipment enclosure.

6. The optical switch assembly of claim 1 , wherein the first member is configured to be secured to a device, and wherein movement of the device causes the second member to move from the first position to the second position.

7. The optical switch assembly of claim 6 , wherein the device is an electronic device.

8. The optical switch assembly of claim 6 , wherein the device is a component of an electronic device.

9. The optical switch assembly of claim 1 , wherein the first member is configured to be secured to an electronic equipment rack.

10. The optical switch assembly of claim 1 , wherein the optical cable second end is directly attached to an optical coupler that is part of the second member.

11. The optical switch assembly of claim 10 , wherein the optical coupler is configured to selectively mate with the second optical cable connector based on a position of a door of an enclosure.

12. An optical switch assembly in combination with a door, the combination comprising:
a door movable between open and closed positions relative to a door frame;
a first member attached to one of the door or door frame;
a second member movably secured to the first member and movable between first and second positions relative to the first member, wherein the second member moves to the second position responsive to movement of the door to an open position;
first and second optical cable connectors attached to the first member; and
an optical cable having opposite first and second ends, wherein the optical cable first end is in optical communication with the first optical cable connector, wherein the optical cable second end is attached to the second member, and wherein movement of the second member to the second position causes the optical cable second end to be in optical communication with the second optical cable connector such that an optical path is established between the first and second optical cable connectors.

13. The combination of claim 12 , further comprising a biasing member that is configured to urge the second member to one of the first or second positions.

14. The combination of claim 12 , wherein the first member is pivotably secured to the second member.

15. The combination of claim 12 , wherein the door is a door of an electronic equipment enclosure.

16. An optical switch assembly in combination with a device, the combination comprising:
a device;
a first member attached to the device;
a second member movably secured to the first member and movable between first and second positions relative to the first member, wherein the second member moves to the second position responsive to movement of the device;
first and second optical cable connectors attached to the first member; and
an optical cable having opposite first and second ends, wherein the optical cable first end is in optical communication with the first optical cable connector, wherein the optical cable second end is attached to the second member, and wherein movement of the second member to the second position causes the optical cable second end to be in optical communication with the second optical cable connector such that an optical path is established between the first and second optical cable connectors.

17. The combination of claim 16 , further comprising a biasing member that is configured to urge the second member to one of the first or second positions.

18. The combination of claim 16 , wherein the first member is pivotably secured to the second member.

19. The combination of claim 16 , wherein the device is an electronic device.

20. The combination of claim 16 , wherein the device is a component of an electronic device.
