Connector Polish Yield at 99% target polish yield: a worked example

Push target polish yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when monitoring LC, SC, MPO/MTP, MT ferrule, or custom optical connector polish quality and rework load.

The inputs for this scenario

  • First-pass accepted polished connectors: 232 connectors (unchanged)
  • Connectors polished: 250 connectors (unchanged)
  • Target polish yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Connector polish yield = first-pass accepted polished connectors รท connectors polished) to the inputs above produces each figure below.
  • At this operating point the engine returns 92.8 % for connector polish first-pass yield, the number this scenario is built around.
  • At this operating point the engine returns 6.2 points for gap to polish-yield target.
  • At this operating point the engine returns 232 connectors for first-pass accepted connectors.
  • At this operating point the engine returns 250 connectors for connectors polished.

How this compares with the baseline

  • Against the tool's baseline example, where target polish yield sits at 95% and the headline result is 92.8 %, this scenario lands almost exactly on the baseline at 92.8 %.
  • It computes the percentage of polished connectors accepted on the first inspection pass and the points by which that sits below your target. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Connector polish first-pass yield: 92.8 % (headline result)
  • Gap to polish-yield target: 6.2 points
  • First-pass accepted connectors: 232 connectors
  • Connectors polished: 250 connectors
