    Contamination of Fixture Affecting Precision

    QUESTION:

    How can contamination of a fixture negatively affect precision and is this directly related to the milled ferrule holes?

     

    ANSWER:

    All fixtures come from the factory with very precisely milled ferrule “bores”, tailored specifically to the particular ferrule which will be polished.  These bores position the ferrule to precise angles to the polishing surface - 90-degrees for PC polishing, other angles (typically 82 degrees, to create an 8-degree finish) for various APC polishing.  (Note:  I use the term “bore” for the circular holes milled into the fiber optic polishing fixture which hold the round ferrule, but the same concepts apply to fixture for rectangular ferrules such as MT.  For simplification, this discussion will reference typical round, PC-finished ferrules, but the concepts all apply to MT fixtures as well as APC fixtures).

    The level of precision to which the fixture holds the ferrules determines many of the ferrule’s geometric characteristics (Apex, Radius, Fiber Height, Ferrule Angle, etc).   Contamination of the fixture can negatively affect this precision, by either pre-maturely wearing of the fixtures dimensions, or by creating buildup in the fixture, which prevents the ferrule from seating properly.
