Claim 0:
1. An optical fiber connector sub-assembly, comprising:
a ferrule configured to hold an optical fiber therein along an axis of an optical fiber connector;
a ferrule holder configured to hold the ferrule at a front portion of the connector;
a ferrule housing including a front portion configured to slidingly receive the ferrule holder and a rear portion configured to be crimped onto an end of a fiber optic cable that includes the optical fiber;
an inner housing configured to be coupled with the ferrule housing;
a spring having a first end configured to be press fit onto a radially outer surface of the ferrule holder and a second end configured to be press fit into a radially inner surface of the ferrule housing;
wherein the ferrule holder, the ferrule housing, and the inner housing are configured to be rotatably fixed to one another;
wherein the ferrule holder is configured to slide axially relative to the inner housing;
wherein the ferrule holder and the ferrule housing are configured to move axially relative to one another along the connector axis between limits defined by an interaction between the ferrule housing, the spring, and the ferrule holder;
wherein the spring is configured to prevent the ferrule from rotating relative to the end of the fiber optic cable while permitting the ferrule holder to slide axially relative to the ferrule housing;
wherein the spring is configured to reduce a load on the ferrule when a load is applied to the fiber optic cable so as to prevent degradation of a signal being transmitted by the fiber.
