Abstract

A connector for optically connecting an optical fiber to an optical fiber port, the connector defining a first length, L 1 , as measured between a leading edge and a trailing edge of the connector when the connector is in a locked configuration, and a second length, L 2 , as measured between the leading edge and the trailing edge of the connector when the connector is in an unlocked configuration, wherein L 1 is different than L 2 . In an embodiment, L 2 is greater than L 1 . In another embodiment, the connector comprises a boot and a housing, and the boot and housing are configured to float relative to one another.

Claims (22)

1. A connector assembly for optically connecting an optical fiber to an optical fiber port, the connector assembly comprising:

a housing configured to receive the optical fiber, the housing including a latch configured to selectively couple the housing to the optical fiber port; and

a boot having a bore configured to receive the optical fiber;

wherein displacing the boot relative to the housing causes a leading end of the latch to move toward a trailing end of the latch so as to unlock the latch from the optical fiber port.

2. The connector assembly of claim 1 , further comprising:

an intermediary element coupled to the latch and the boot, wherein displacing the boot relative to the housing causes the intermediary element to bias the latch to an unlocked configuration.

3. The connector assembly of claim 2 , wherein the intermediary element comprises an engagement feature configured to engage with a complimentary engagement feature on the boot, the complementary engagement feature being configured to transmit force applied on the boot to the latch of the housing.

4. The connector assembly of claim 1 , wherein the housing and boot are disposed at a first relative position with respect to one another when the connector is in a locked configuration and a second relative position with respect to one another when the connector is in an unlocked configuration, and wherein the second relative position includes a gap between the housing and boot with a gap size greater than a gap in the first relative position.

5. The connector assembly of claim 1 , wherein a length of the connector, as measured between a leading edge of the housing and a trailing edge of the boot, changes when the connector is transitioned between locked and unlocked configurations.

6. The connector assembly of claim 5 , wherein the length is greater in the unlocked configuration.

7. The connector assembly of claim 1 , wherein the latch comprises a first radius of curvature in the locked configuration and a second radius of curvature in the unlocked configuration, and wherein the first radius of curvature is greater than the second radius of curvature.

8. The connector assembly of claim 1 , wherein the optical fiber comprises a receiving fiber and a transmitting fiber, and wherein relative positions of the receiving and transmitting fibers are reversible with respect to the latch.

9. A method of releasing a connector from an optical fiber port, the method comprising:

applying a biasing force to a boot of the connector in a direction away from a housing of the connector, the housing comprising a latch configured to selectively couple the connector to the optical fiber port, wherein applying the biasing force to the boot causes a length of the latch, as measured by a length between a leading end of the latch and a trailing end of the latch, to change; and

removing the connector from the optical fiber port after the latch is transitioned to an unlocked configuration.

10. The method of claim 9 , wherein applying the biasing force to the boot causes an intermediary element coupled between the boot and the latch to move the latch from a locked configuration to an unlocked configuration.

11. The method of claim 9 , wherein applying the biasing force to the boot causes the length of the connector to increase.

12. The method of claim 9 , wherein the boot and housing are spaced apart by a gap having first distance, D 1 , as measured when the connector is in a locked configuration, and a second distance, D 2 , as measured when the connector is in an unlocked configuration, and wherein D 2 is greater than D 1 .

13. The method of claim 9 , wherein the housing contains a receiving fiber and a transmitting fiber, and wherein relative positions of the receiving and transmitting fibers are reversible with respect to the latch.

14. The method of claim 9 , further comprising installing the connector into the same or another optical fiber port, wherein the length of the connector remains unchanged during installation into the same or other optical fiber port.

15. The connector assembly of claim 1 , wherein the boot comprises an integrated boot including the boot and a handle, and wherein the handle is configured to transmit displacement of the boot to the latch.

16. A connector for optically connecting an optical fiber to an optical fiber port, the connector comprising a housing configured to receive the optical fiber, wherein the housing includes a latch configured to selectively couple the housing to the optical fiber port, wherein the latch is configured to be coupled with a boot such that displacement of the boot relative to the housing causes a leading end of the latch to move toward a trailing end of the latch so as to unlock the latch from the optical fiber port.
