Centroc GP

Centroc GP

Fiber Optic Tuner for measurement of geometrical parameters at fiber optic connectors.

Eccentricity/Concentricity Measurement and Tuning

for Minimizing Insertion Loss of Fiber Optic Connectors.



Key Features

      +Fiber and FerruleVisual examination
      +Eccentricity or Concentricity Measurements of Fiber Core w.r.t Ferrule Outside Diameter
      +Ferrule Cylindricity Assessment
      +Angular Tuning of PC connectos for Minimum Insertion Loss (After PC Polishing)
      +Angular Tuning of APC Connectors for Optimal Angular Polishing and Minimum Insertion Loss (Before APC

         Polishing)

The CentrocGP is a specially designed auto-focus microscope with a digital camera and precision chucks. The

system performs measurements of fiber optic core eccentricity with respect to ferrule outside diameter of

connectors, and provides the basis for angular tuning of PC-type (@ post PC polishing) and APC-type (@ pre-APC

polishing) connectors.

The PC controlled unit is equipped with universal active devices (LEDs @ 475nm and 630 nm) for connector types

equipped with 2.50mm and1.25mm ferrules. Measurement fixtures are available for all standard connectors and

ferrules.

The system collects a pre-selected number of focused imaging scans from the fully filled illuminated fiber core.

Between the scans the connector is rotated in steps of 45, 60 or 90 degrees. Digital images are processed by

machine vision software and the following results are supplied:

The Eccentricity Amplitude as defined from the center of the ferrule outside diameter to the fiber core center

(Quick switch between Eccentricity and Concentricity outputs is available)

The Eccentricity Angle relative to Key Orientation

The Cylindricity of ferrule outside diameter
