Stress conditions
If temperature, humidity or power-aging evaluation is required, specify the conditions and discuss the applicable test scope with engineering.
Quality & Reliability
Acceptance criteria, test conditions and records that make a component's performance assessable.

A test value is useful only when its conditions and acceptance limit are clear. Use the selected product specification and confirmed configuration as the common reference for evaluating the supplied component.
Acceptance & inspection
The following are review points for an inspection plan. Applicable items and report requirements depend on the selected component and order.
| Review area | What to agree | What the record should identify |
|---|---|---|
| Optical performance | Applicable loss, isolation, return loss, splitting ratio or other model-specific limits. | Parameter, measured result, acceptance limit, wavelength and port direction. |
| Fiber & PM configuration | Fiber type and dimensions, port mapping and polarization requirements where applicable. | The selected fiber interfaces and the conditions used for a PM measurement. |
| Power & thermal conditions | Operating power, duty cycle and cooling or mounting conditions relevant to the design. | The applied conditions and any separately agreed qualification procedure. |
| Mechanical & shipment details | Package, pigtails, connector type, identification and packaging requirements. | Configuration or drawing reference and agreed delivery documentation. |
Report format, sample identification and any additional inspection requirements should be agreed before the order is confirmed.
Reliability evaluation
Environmental or endurance evaluation must be tied to the actual component and application. Routine optical measurements alone do not establish service life.
If temperature, humidity or power-aging evaluation is required, specify the conditions and discuss the applicable test scope with engineering.
Agree on exposure time or cycles, monitoring points, and the limits used to compare performance before and after testing.
Check that the evaluated fiber, package, power and cooling conditions correspond to the intended use. Qualification scope is confirmed for the selected design.
Identification & repeat orders
For repeat builds and quality reviews, agree on the identification and records needed to distinguish the supplied configuration.
When a result needs review
An order or item reference, measured result and test conditions provide a basis for investigating a discrepancy. Wavelength, power, port direction, setup details and connection photos help relate the result to the confirmed specification.
Plan the quality requirements early
Include the acceptance limits, required records and any qualification conditions with the information already available.
