Abstract

Narrow width fiber optic connectors having spring loaded remote release mechanisms to facilitate access and usage of the connectors in high density arrays. A narrow width fiber optic connector comprises a multi-fiber connector, wherein a width of said narrow width fiber optic connector is less than about 12.4 mm, a housing configured to hold the multi-fiber connector and further comprising a connector recess, and a pull tab having a ramp area configured to disengage a latch of one of an adapter and an SFP from said connector recess. The pull tab may include a spring configured to allow the latch of one of the adapter and the SFP to engage with the connector recess.

Claims

1. A narrow width fiber optic connector for releasable connection to a latch of one of an adapter or an SFP, the narrow width fiber optic connector comprising:

a plurality of optical fibers;

a housing configured to hold the plurality of optical fibers and further comprising a connector recess; and

a pull tab having a ramp area configured to disengage the latch of one of the adapter or the SFP from said connector recess, wherein the latch is within a main cavity of the one of the adapter and the SFP, the pull tab being mounted on the housing for movement between a displaced position and an undisplaced position and including a spring biasing the pull tab toward the undisplaced position.

2. The narrow width fiber optic connector of claim 1, further comprising one of a multi-fiber MT ferrule and at least one LC ferrule.

3. The narrow width fiber optic connector of claim 1, wherein the width is less than or equal to about 9.6 mm.

4. The narrow width fiber optic connector of claim 1, wherein the spring is configured to allow the latch of one of the adapter and the SFP to engage with the connector recess.

5. The narrow width fiber optic connector of claim 1, wherein a width of said narrow width fiber optic connector is less than about 12.4 mm.

6. The narrow width fiber optic connector of claim 1 wherein the spring is supported by the housing.

7. The narrow width fiber optic connector of claim 6 wherein the spring directly engages the housing and the pull tab.

8. The narrow width fiber optic connector of claim 6 wherein the housing includes a recess configured to accommodate at least a portion of the spring.

9. The narrow width fiber optic connector of claim 1 further comprising a cable boot extending rearward from adjacent the housing along a cable boot length, wherein the pull tab comprises a single piece comprising a front end portion defining the ramp area and a tab portion extending rearward from the front end portion to a rear end of the pull tab, the tab portion overlapping the cable boot along at least a majority of the cable boot length.

10. A narrow pitch fiber optic connector for releasable connection to a latch of one of an adapter or an SFP, the narrow pitch fiber optic connector comprising:

a plurality of LC connectors arranged such that a pitch of said narrow pitch connector is less than about 5.25 mm;

a housing configured to hold the plurality of LC connectors and further comprising a connector recess; and

a pull tab having a ramp area configured to disengage the latch of one of the adapter and the SFP from said connector recess, wherein the latch is within a main cavity of the one of the adapter and the SFP, the pull tab being mounted on the housing for movement between a displaced position and an undisplaced position and including a spring biasing the pull tab toward the undisplaced position.

11. The narrow pitch fiber optic connector of claim 10, wherein the pitch is less than or equal to about 4.8 mm.

12. The narrow pitch fiber optic connector of claim 10, wherein the spring is configured to allow the latch of one of the adapter and the SFP to engage with the connector recess.

13. The narrow pitch fiber optic connector of claim 12, wherein the pull tab includes a distal end for remotely unlatching the narrow pitch connector.

14. The narrow pitch fiber optic connector of claim 10, wherein the narrow pitch connector is a duplex connector.

15. The narrow pitch fiber optic connector of claim 10, wherein the housing includes a bottom housing and a top housing coupled to the bottom housing.

16. The narrow pitch fiber optic connector of claim 15, wherein the bottom housing includes a side wall configured to open.

17. The narrow pitch fiber optic connector of claim 16, wherein the side wall includes a raised profile at a rear end thereof.

18. The narrow pitch fiber optic connector of claim 10 wherein the spring is supported by the housing.

19. The narrow pitch fiber optic connector of claim 18 wherein the spring directly engages the housing and the pull tab.

20. The narrow pitch fiber optic connector of claim 18 wherein the housing includes a recess configured to accommodate at least a portion of the spring.
