Abstract

Devices and methods for connecting optical fibers are provided. In some embodiments, connectors and adaptors for two-fiber mechanical transfer type ferrules are disclosed. In some embodiments, MT connectors, such as simplex, duplex, and quad micro-MT adaptors are disclosed. In some embodiments, MT adaptors, such as simplex, duplex, and quad adaptors are disclosed. In some embodiments, optical fiber cables that modularly coupled with at least one optical fiber connector, adaptor, and other optical fiber cable using a remote release are disclosed.

First claim

What is claimed is:

1. An optical fiber connector configured to be coupled with an adaptor, the connector comprising:
a. at least one housing defining a longitudinal passage therethrough;
b. a latch body defining a longitudinal passage therethrough and being movably coupled to the at least one housing, wherein at least part of the at least one housing is movably within the longitudinal passage of the latch body;
c. at least one latch spring defining a longitudinal passage therethrough and being movably coupled with the at least one housing;
d. at least one ferrule extending longitudinally from a first end to a second end, the ferrule disposed at least partially within the longitudinal passage of the at least one housing with the first end protruding external to the longitudinal passage of the at least one housing; and
e. a ferrule spring disposed in the longitudinal passage of the at least one housing and coupled to the ferrule.

2. The optical fiber connector of claim 1 , wherein the connector is a simplex micro-MT connector, a duplex micro-MT connector, or a quad micro-MT connector.

3. The optical fiber connector of claim 1 , wherein the at least one ferrule is a multi-fiber MT ferrule.

4. The optical fiber connector of claim 1 , wherein an end face of the at least one ferrule has a width in a range of about 2.4 mm to about 3.6 mm.

5. The optical fiber connector of claim 1 , wherein an end face of the at least one ferrule has a height in a range of about 1.0 mm to about 1.6 mm.

6. The optical fiber connector of claim 1 , wherein the connector has a width in a range of about 6.4 mm to about 19.2 mm.

7. The optical fiber connector of claim 1 , wherein the connector has a height in a range of about 3.8 mm to about 11.8 mm.

8. The optical fiber connector of claim 1 , wherein the connector has a length in a range of about 17.0 mm to about 30.2 mm.

9. The optical fiber connector of claim 1 , wherein the latch body is coupled with a pull-tab.

10. The optical fiber connector of claim 9 , wherein the pull-tab comprises a first end and a second end spaced from the first end, the first end comprises at least one latch hook coupled with the latch body, and the second end is configured to actuate the connector.

11. The optical fiber connector of claim 10 , wherein the adaptor has a width in a range of about 8 mm to about 12 mm.

12. The optical fiber connector of claim 10 , wherein the adaptor has a height in a range of about 6 mm to about 33 mm.

13. The optical fiber connector of claim 10 , wherein the adaptor has a length in a range of about 20 mm to about 30 mm.

14. The optical fiber connector of claim 10 , wherein the second end is configured to actuate the latch body and the at least one latch spring.

15. The optical fiber connector of claim 14 , wherein the adaptor comprises at least one mounting handle.

16. The optical fiber connector of claim 14 , wherein the adaptor comprises at least one flange.

17. The optical fiber connector of claim 1 , wherein the adaptor comprises:
a. a housing defining a longitudinal passage therethrough, the housing comprising at least one mounting tab, wherein a first wall, a second wall, a third wall, and a fourth wall, wherein the first wall and the third wall are opposite to each other, wherein the second wall and the fourth wall are opposite to each other, and wherein the second wall comprises at least one adaptor housing hole; and
b. at least one latch-hook arm defined by a first side, a second side, a first end, and a second end spaced from the first end, wherein the first end and the second end each comprise a first hook configured to couple with the connector, wherein one of the sides comprises a second hook to couple with an adaptor housing hole.

18. The optical fiber connector of claim 17 , wherein the adaptor is a simplex micro-MT adaptor, a duplex micro-MT adaptor, or a quad micro-MT adaptor.
