Photonics Test Time at 11% calibration and warm-up allowance: a worked example

This worked example runs the photonics test time numbers for a tougher week than the baseline: 11% calibration and warm-up allowance instead of the typical 15%. Estimate total testing time for photonics devices (laser modules, detectors, fiber assemblies) based on the number of units, test cycle time per unit, and setup allowance for calibration and fixture changes.

The inputs for this scenario

  • Units requiring optical test: 60 units (held at the documented default)
  • Test station throughput: 6 units / hr (held at the documented default)
  • Calibration and warm-up allowance: 11 % (the input this scenario stresses; the baseline uses 15)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base test time = units requiring test / test throughput.
  • Total photonics test time works out to 11.1 hr at these inputs, and this is the headline figure for the scenario.
  • Base test time works out to 10 hr at these inputs.
  • Calibration and warm-up time added works out to 11 % at these inputs.
  • Test throughput works out to 6 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where calibration and warm-up allowance sits at 15% and the headline result is 11.5 hr, this scenario comes in 3.48% below the baseline at 11.1 hr.
  • Use it to schedule a qualification batch, check whether one test station can meet a deadline, or estimate test labor and capacity for a photonics build. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total photonics test time: 11.1 hr (headline result)
  • Base test time: 10 hr
  • Calibration and warm-up time added: 11 %
  • Test throughput: 6 pieces / min

Run it with your numbers
