Abstract

Described are examples of optical blind-mate connector adaptors, optical blind-mate connectors to blind-mate to the adaptors, and optical blind-mate systems. In various implementations, an optical blind-mate connector adapter may include a sleeve, a shutter mounted on a pivot at an opening of the sleeve to move between a closed position and an open position extending into the sleeve, and a cantilever spring anchored to a wall of the sleeve and including a free end extending toward the opening of the sleeve to urge the shutter to the closed position.

First claim

What is claimed is:

1. An apparatus to optically blind-mate to an optical module, the apparatus comprising:
a sleeve;
a shutter mounted on a pivot at an opening of the sleeve to move between a closed position and an open position extending into the sleeve, the shutter including a tab facing an interior of the sleeve; and
a cantilever spring anchored to a wall of the sleeve and including a free end extending toward the opening of the sleeve to engage the tab to urge the shutter to the closed position.

2. The apparatus of claim 1 , wherein the cantilever spring is anchored to the wall of the sleeve at an anchor end, and wherein the free end urges the shutter toward the closed position.

3. The apparatus of claim 2 , wherein the free end is angled away from the wall to engage the tab to urge the shutter toward the closed position.

4. The apparatus of claim 1 , wherein the opening is a first opening disposed at a first distal end of the sleeve, and wherein the apparatus includes another shutter mounted at a second opening disposed at a second distal end of the sleeve.

5. The apparatus of claim 1 , further comprising a housing, wherein the sleeve is disposed within the housing.

6. The apparatus of claim 5 , further comprising a circuit board, and wherein the housing comprises a first housing end at a first side of the circuit board and a second housing end at a second side, opposite the first side, of the circuit board.

7. The apparatus of claim 1 , wherein the apparatus is a connector adapter to blind-mate a pair of optical modules to each other.

8. An apparatus to optically blind-mate to an optical connector adapter, the apparatus comprising:
a housing;
an optical ferrule assembly at least partially within the housing; and
an actuator plate slidably coupled to the housing, the actuator plate to cause an end of the optical ferrule assembly to extend from housing when the housing is inserted into the optical connector adapter.

9. The apparatus of claim 8 , wherein the optical ferrule assembly is to move between a retracted position when the actuator plate is in a first position to an extended position when the actuator plate is in a second position.

10. The apparatus of claim 9 , wherein the optical ferrule assembly includes a ferrule carrier holding a plurality of optical fibers and including a knob on a surface of the ferrule carrier, the knob to mate with a slot in the housing and to slide within the slot between the retracted position and the extended position.

11. The apparatus of claim 8 , further comprising a slide plate disposed between the actuator plate and the housing to urge the optical ferrule assembly to extend from the housing when the actuator plate moves from a first position to a second position relative to the housing.

12. The apparatus of claim 11 , wherein the slide plate includes a tab to slidably nest within a first slot in the actuator plate such that the slide plate is to move transversely to the actuator plate when the actuator plate moves from the first position to the second position, and wherein the optical ferrule assembly includes a knob extending through a second slot in the housing to slidably nest within a third slot in the slide plate such that the optical ferrule assembly moves between a retracted position when the actuator plate is in the first position to an extended position when the actuator plate is in the second position.

13. A system comprising:
a connector adapter including a sleeve, a shutter pivotable between a closed position and an open position extending into an interior of the sleeve, and a cantilever spring along a wall of the sleeve to urge the shutter to the closed position; and
an optical connector to blind mate to another optical connector through the sleeve, the optical connector including a housing, an optical ferrule assembly at least partially within the housing, and an actuator plate, the housing to push the shutter to an open position and the actuator plate to engage an end edge of the connector adapter and slide along the housing to cause an end of the optical ferrule assembly to extend from the housing as the optical connector is inserted into the sleeve.

14. The system of claim 13 , wherein the housing, the optical ferrule assembly, and the actuator plate are in sliding arrangement with each other.

15. The system of claim 13 , wherein the shutter is a first shutter mounted at a first opening of the sleeve, and wherein the connector adapter includes a second shutter mounted at a second opening of the sleeve, opposite the first opening, the second shutter to pivot from a closed position to an open position extending into an interior of the sleeve when the other optical connecter is inserted into the sleeve through the second opening.

16. The apparatus of claim 1 , wherein the shutter includes a film to provide dust protection.

17. The apparatus of claim 16 , wherein the film seals around a perimeter of the shutter.

18. The apparatus of claim 1 , wherein the shutter is coated with a material to prevent optical signal reflection.

19. The apparatus of claim 1 , comprising:
a shutter rest, wherein the shutter rests against the shutter rest when the shutter is in the closed position.

20. The apparatus of claim 1 , wherein the cantilever spring is tapered.
