  3.) “AUTO-DETECT”. Designed to meetIEC61300-3-35,theseinstruments will determine a ‘pass/fail’ within the
offset by a remarkably extensive field- of-view. Seeing ‘more’ results in a better cleaning procedure. Exhaustive
      parameters of that standard. Existing
‘auto-detect’ devices only characterize
the surface as defined in Image-1. This is
a good minimum requirement: it is not
“best practice”. Studies have revealed there is potential for debris on unseen connector surfaces. The limited ‘field of view” of an auto-detect system conveys a false sense that the connector may be clean when, in reality, debris can move from outside of the ‘primary’ inspected surface. This does not mean not to consider this device; it does mean to be aware of the weak links. As of Fall 2022, there is some thought to expand the field of view. Common sense awareness teaches that surfaces extend beyond what you are seeing. Debris itself is problematic: fluids move about, dry debris can regenerate itself by static fields, and existing standards only consider ‘easy-to-remove’ types. I test with dry, fluidic© and combinations of the two: worst case. “Auto-detect” is an important advance. Your customer may require this standard and recording of each cleaning event. These instruments have amazing capabilities.
4.) DIGITAL PHOTOGRAPHY: PC or Android base, digital photography provides the most comprehensive views of “primary” and “secondary surfaces”. The ‘weak link’ is lower magnification:
research and more than 20 years of field
work have proven an effective ‘solvent-
transfer’ cleaning procedure removes
end face debris from the complete Zone-
4 horizontal end face. Rather than multiple cleaning efffforts, oftentimes the surface is cleaned the 1st time. Please check www. fiberopticprecisioncleaning.com for references to update the knowledge base and retrain-the-trainer programs.
