Abstract

A method of connecting a ferrule to an optical fiber polishing fixture assembly comprises obtaining a fixture base to which a clamping assembly is operatively connected, positioning a lever in an unlocked position thereby creating a gap between first and second base portions, obtaining a fiber optic connector and cable assembly including a ferrule operatively connected to a cable, positioning the ferrule in a ferrule bore, and moving the lever from the unlocked position to a locked position thereby causing the first and second base portions to engage the fiber optic connector and cable assembly.

Claims (7)

1. A method of connecting a ferrule to an optical fiber polishing fixture assembly, comprising:

obtaining a fixture base to which a clamping assembly is operatively connected, the fixture base having a receiving cavity in which a ferrule support having a ferrule bore is positioned, the clamping assembly having first and second base portions, a lever, and a biasing member, the first base portion having a first inner facing side with a first inner facing surface, the second base portion having a second inner facing side with a second inner facing surface, the lever having a first end positioned between the first and second inner facing surfaces and a second end extending outward therefrom, and the biasing member biasing the first and second base portions toward each other, the first and second base portions, the first end of the lever, and the biasing member being configured and arranged to be received in the receiving cavity and operatively connected to the fixture base, the clamping assembly having a locked position and an unlocked position, the locked position being when the first and second base portions are biased toward one another, the unlocked position being when the lever overcomes a biasing force of the biasing member and separates the first and second base portions, wherein as the lever is moved from the locked position to the unlocked position, the lever overcomes the biasing force and moves the first and second base portions away from one another;

positioning the lever in the unlocked position thereby creating a gap between the first and second base portions;

obtaining a fiber optic connector and cable assembly including a ferrule operatively connected to a cable;

positioning the ferrule in the ferrule bore; and

moving the lever from the unlocked position to the locked position thereby causing the first and second base portions to engage the fiber optic connector and cable assembly.

2. The method of claim 1 , wherein the first base portion includes a first slot in the first inner facing side, the second base portion includes a second slot in the second inner facing side, and the fiber optic connector and cable assembly includes bars on opposing sides, the method further comprising positioning the bars in the first and second slots in the locked position.
