Optical fiber connector for minimizing signal transmission losses

An optical fiber connector subassembly for reducing signal transmission losses in an optical fiber connector comprising:

• a ferrule assembly having a ferrule and a ferrule basket configured to hold the ferrule,
• a carrier having a front sleeve and a rear sleeve configured to be rotationally fixed to the front sleeve,
• a polygonal biasing member configured to be disposed between the ferrule basket and the carrier, rotationally fixed with the ferrule assembly, and rotationally fixed with the carrier, and
• wherein the carrier is configured to be rotationally fixed relative to the inner housing and the outer housing;
• wherein the polygonal biasing member includes a rear portion configured to be received in an engagement structure defined by the rear sleeve and a front portion configured to be received on a an engagement portion of the ferrule basket;
• wherein the polygonal biasing member is configured to bias the ferrule assembly toward a front abutment surface of the carrier along a connector axis;
• wherein the engagement structure is configured to define a plurality of predetermined rotational positions for tuning the connector;
• wherein the polygonal biasing member is disposed at one of the plurality of predetermined positions relative to the carrier;
• wherein the one of the plurality of predetermined positions comprises an position selected to tune the connector by optimizing a position of the ferrule and a fiber terminated by the ferrule relative to the carrier to minimize signal loss when the ferrule abuts a mating ferrule;
• wherein the polygonal biasing member is configured to maintain the ferrule in the optimized position and to prevent rotation of the ferrule relative to the carrier;
• and
• wherein the polygonal biasing member is configured to permit the ferrule assembly to float relative to the carrier to optimize alignment of the ferrule relative to the mating ferrule when the ferrule abuts the mating ferrule so as to minimize signal transmission losses between the ferrule and the mating ferrule.

• and
• wherein the polygonal biasing member is configured to maintain the ferrule at the selected one of the plurality of predetermined tuning positions so as to optimize alignment of the ferrule with a mating ferrule when the ferrule abuts the mating ferrule and mitigate against signal transmission losses between the ferrule and the mating ferrule when the ferrule assembly is at the selected one of the plurality of predetermined tuning positions.

An optical fiber connector for achieving reduced signal transmission losses comprising:

• a ferrule basket portion configured to hold a ferrule portion and be disposed in one of a plurality of predetermined tuning positions;
• a carrier portion configured to engage the ferrule basket portion;
• and
• a polygonal biasing member configured to engage the ferrule basket portion and the carrier portion so as to maintain the ferrule basket portion at one of the plurality of predetermined tuning positions and mitigate against signal transmission losses between the ferrule portion and a mating ferrule when the ferrule basket portion is at the one of the plurality of predetermined tuning positions.
