The measurement, today

End-face grading is a technician looking down a scope and making a pass or fail call. The zone boundaries and the size thresholds live in their head, and the result is not logged with the image.

What it costs

A scratch across the core or debris on the contact zone raises insertion and return loss, which surfaces later as a link that will not certify. Re-terminating in the field costs far more than catching it at assembly.

From image to reviewed result

  1. 1

    Image the end-face

    Load an inspection-scope image of the polished connector end-face.

  2. 2

    Register the zones

    The four concentric zones (core, cladding, adhesive, ferrule) are placed on the fibre.

  3. 3

    Detect and size

    Scratches and defects are separated and measured within each zone.

  4. 4

    Apply the criteria

    The per-zone count-and-size rules give a pass or fail for every zone.

Scope: Applies the IEC 61300-3-35 zone-and-size counting rules to the end-face image. Pass and fail thresholds vary by connector type; select the ruleset that matches your connector.
