Abstract

An apparatus for releasably attaching a fiber optic module to equipment is disclosed. The apparatus comprises a latch configured to releasably attach the fiber optic module to equipment. The apparatus further comprises a pushrod configured to deactivate the latch from a back end of the fiber optic module, wherein the fiber optic module is released from the equipment. In one embodiment, the fiber optic module is a high-density fiber optic module. The pushrod may be further configured to maintain a position of the latch. The pushrod may also be further configured to be positioned in a groove disposed in a side of a main body of the fiber optic module, wherein the pushrod and the groove are configured to prevent the pushrod from binding while moving within the groove.

First claim

What is claimed is:

1. A fiber optic module comprising:
an interior;
at least one adapter disposed in one end of the fiber optic module having a fiber optic connector configured to connect to one or more optical fibers;
at least one fiber management feature provided within the interior of the fiber optic module;
wherein the at least one fiber management feature is configured to provide fiber management for the one or more optical fibers within the interior of the fiber optic module;
a latch configured to releasably attach the fiber optic module to equipment; and
a pushrod positioned in a groove disposed in a side of a main body of the fiber optic module, wherein the pushrod is configured to deactivate the latch from a back end of the fiber optic module;
a pinch grip disposed on one end of the fiber optic module, the pinch grip configured to actuate the pushrod when a pressure is applied to the pinch grip,
wherein the pinch grip has an arm and a lever, each providing a respective pinch surface.

2. The fiber optic module of claim 1 , wherein the at least one fiber management feature comprises a plurality of fiber management features.

3. The fiber optic module of claim 1 , wherein the at least one fiber management feature comprises a splice holder assembly positioned in the interior, wherein the splice holder assembly comprises a single fiber splice holder assembly and a ribbon fiber splice holder mounted on a common base.

4. The fiber optic module of claim 1 , wherein the at least one fiber management feature comprises a bend radius control attached to the interior of the fiber optic module.

5. The fiber optic module of claim 4 , wherein the bend radius control is configured to allow for fiber routing within the interior of the fiber optic module and to provide a bend radius of between approximately twenty (20) and twenty-five (25) millimeters (mm).

6. An apparatus for releasably attaching a fiber optic module to equipment, comprising:
a latch configured to releasably attach the fiber optic module to the equipment; and
a pushrod configured to deactivate the latch from a back end of the fiber optic module, wherein the fiber optic module is released from the equipment;
a pinch grip disposed on one end of the fiber optic module, the pinch grip configured to actuate the pushrod when a pressure is applied to the pinch grip,
wherein the pinch grip has an arm and a lever, each providing a respective pinch surface.

7. The apparatus of claim 6 , wherein the pushrod is further configured to be positioned in a groove disposed in a side of a main body of the fiber optic module.

8. The apparatus of claim 7 , wherein the pushrod and the groove are configured to prevent the pushrod from binding while moving within the groove.

9. The apparatus of claim 7 , further comprising a compression spring configured to be placed on to one end of the pushrod and over a guide post connected to the fiber optic module, wherein the spring is captured in the one end of the pushrod and a force of the spring biases the pushrod toward one end of the groove.

10. The apparatus of claim 7 , further comprising a stop provided in a notch disposed in a wall of the fiber optic module, wherein the stop is configured to stop a travel of the pushrod within the groove.

11. The apparatus of claim 6 , further comprising a detent provided in the pinch grip, the detent configured to prevent the pinch surfaces from sliding, such that a travel of the pushrod within the groove is maximized.

12. The apparatus of claim 11 , wherein the detent comprises a protrusion and a slot, the protrusion configured to be selectably insertable into the slot when a pressure is applied to the pinch grip.

13. The apparatus of claim 11 , wherein the latch further comprises a resiliently moveable support member attached to a side of the fiber optic module.

14. The apparatus of claim 13 , wherein a retention clip and an actuator extend from the resiliently moveable support member, the retention clip is configured to releasably maintain the fiber optic module in the equipment.

15. The apparatus of claim 14 , wherein the pushrod has a first end and a second end, wherein when the lever is moved, the lever is configured to apply a force to the first end of the pushrod forcing the pushrod to travel in the groove toward a front end of the fiber optic module until the stop stops the pushrod or the pinch surfaces make contact.

16. The apparatus of claim 15 , wherein when the lever is moved and the pushrod travels in the groove toward a front end of the fiber optic module, a first angled surface of the second end of the pushrod is configured to contact a complementary second angled surface of the actuator and is configured to apply a pressure to the complementary second angled surface, thereby causing the resiliently moveable support member, and in turn the retention clip, to move towards an interior of the fiber optic module and release the fiber optic module from the equipment.

17. The apparatus of claim 16 , wherein the lever is configured to automatically move away from the arm when a pressure on the lever is released, causing the force on the first end of the pushrod to be released and a resulting release of pressure from the first angled surface against the complementary second angled surface.

18. The apparatus of claim 17 , wherein the resulting release of pressure from the first angled surface against the complementary second angled surface allows the support member and the retention clip to automatically move away from the interior of the fiber optic module, wherein the second angled surface applies a pressure on the first angled surface, forcing the pushrod to travel toward a back end of the fiber optic module and into a deactivated state.

19. The apparatus of claim 6 , wherein the pushrod is positioned outside an interior of the fiber optic module.

20. The apparatus of claim 6 , wherein the pushrod is further configured to maintain a position of the latch.

21. The apparatus of claim 6 , wherein the lever is configured to be resiliently moved toward the arm to activate the pushrod.
