Abstract

A method of terminating an optical fiber drop cable with an optical fiber connector and said optical fiber connector are described herein wherein said optical fiber connector can be inserted into a port structure of a telecommunication enclosure to provide an environmentally sealed connection. The exemplary connector has a main body with an interior passageway extending from a first end to a second end of the main body and a compressible portion at the second end of the main body, a compression member attachable to the second end of the optical fiber connector over the compressible portion, an optical connection portion disposed at least partially within the interior, and an outer housing disposed over the connection portion wherein the outer housing has an external shape mateable with a standard format optical coupling.

First claim

We claim:

1. A method of terminating an optical fiber drop cable with a ruggedized optical fiber connector, the method comprising:
stripping and cleaving a terminal end of the optical fiber drop cable to reveal a bare glass portion of an optical fiber;
securing the bare glass portion of the optical fiber in a fiber optic connector body of an optical connection portion;
sliding the optical connection portion through an interior passage way of a main body of the ruggedized optical fiber connector;
connecting an outer housing over the optical connection portion;
securing the outer housing at a first end of the main body;
positioning an internal sealing member at a second end of the main body; and
compressing the internal sealing member longitudinally between the second end of the main body and a compression member to create an environmental seal between the cable and the main body of the ruggedized connector.

2. The method of claim 1 , further comprising the step of curing an adhesive in the connection portion to secure the bare glass portion.

3. The method of claim 1 , further comprising the step of activating a mechanical splice device disposed within the connection portion to secure the bare glass portion.

4. The method of claim 1 , further comprising the step of screwing the compression member onto the second end of the main body to compress the internal sealing member.

5. An environmentally sealing optical fiber connector, the connector comprising:
a main body having an interior passageway extending from a first end to a second end of the main body;
an outer housing integrally formed on the first end of the main body, wherein the outer housing has an external shape mateable with a standard format optical coupling;
a compression member attachable to the second end of the main body;
an optical connection portion secured in the outer housing, wherein the interior passageway is configured to allow the optical connection portion to be slid through the main body from the second end to the first end; and
an internal sealing member that is compressed longitudinally between the compression member and the main body when the compression member is attached to the second end of the main body to provide an environmental seal between the main body and an optical fiber cable onto which the optical fiber connector is mounted.

6. The connector of claim 5 , wherein the outer housing is shaped to mate with an SC-format optical coupling.

7. The connector of claim 5 , further comprising a port connection mechanism.

8. The connector of claim 7 , wherein the port connection mechanism comprises a spring clip.

9. The connector of claim 7 , wherein the port connection mechanism comprises a plurality of protrusions extending from an exterior surface of the main body and a release lever.

10. The connector of claim 5 , wherein the main body comprises at least two body portions.

11. The connector of claim 10 , wherein the main body comprises a first body portion housing the connector portion and a second body portion to grip a sheath of the optical fiber cable passing therethrough.

12. The connector of claim 10 , wherein the main body comprises a first body portion housing the connector portion and a second body portion to grip the sheath of an optical fiber cable passing therethrough and an intermediate body portion that provides an environmental seal between the cable and the connector.

13. The connector of claim 5 , wherein the main body comprises at least two body portions and wherein the connector further comprising an optical fiber cable terminated by the optical fiber cable connector where in the optical fiber cable includes a plurality of first strength members secured within the optical connector portion and a plurality of second strength members, wherein the second strength members are secured between two of the at least two body portions.

14. The connector of claim 5 , wherein the internal sealing member comprises an elastomeric portion and a rigid portion.
