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 12.4mm, 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 comprising:

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.

2. The narrow width fiber optic connector of claim 1, wherein the multi-fiber connector includes a multi-fiber MT 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 pull tab includes a spring configured to allow the latch of one of the adapter and the SFP to engage with the connector recess.

5. A 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 a latch of one of an adapter and an SFP from said connector recess.

6. The narrow pitch fiber optic connector of claim 5, wherein the pitch is less than or equal to about 4.8 mm.

7. The narrow pitch fiber optic connector of claim 5, wherein the pull tab includes a spring configured to allow the latch of one of the adapter and the SFP to engage with the connector recess.

8. The narrow pitch fiber optic connector of claim 7, wherein the pull tab includes a distal end for remotely unlatching the narrow pitch connector.

9. The narrow pitch fiber optic connector of claim 5, wherein the narrow pitch connector is a duplex connector.

10. The narrow pitch fiber optic connector of claim 5, wherein the housing includes a bottom housing and a top housing coupled to the bottom housing.

11. The narrow pitch fiber optic connector of claim 10, wherein the bottom housing includes a side wall configured to open.

12. The narrow pitch fiber optic connector of claim 11, wherein the side wall includes a raised profile at a rear end thereof.
