Direct answer
Review vibration capability for a specific assembly and test configuration. IP68, armor and connector appearance do not establish it. A report should identify specimens, fixtures, routing, vibration conditions and optical criteria. Passing static loss does not validate performance under vibration.
Definition and applications
IEC 61300-2-1:2023 addresses sinusoidal vibration and its effects on optical-device attenuation. Do not label that evidence as random-vibration, shock or universal transport qualification. Select the project test combination from its actual exposures.
Relevant applications include industrial cabinets, equipment-adjacent connections and mechanically excited routing. State the mounting location, attachment and surrounding moving structures; industrial-grade branding is not a substitute. Responsible engineering and test personnel should review the actual procedure.
Evidence table
| Item | Evidence | Avoid |
|---|---|---|
| Specimen | Interfaces, cable, assembly and revision | Family-wide assumptions |
| Mounting | Fixtures, fastening, free lengths and route | Unrepresentative mounting |
| Excitation | Method, directions and condition record | Grade label alone |
| Optics | Channels, wavelengths, acquisition and criteria | Static report alone |
| Exceptions | Raw records, retests and explanations | Final pass statement only |
Procurement workflow
Compare installation and test drawings side by side. Mark differences and review applicability after changes to attachment positions, free lengths or materials. Do not improve test mounting without documenting why the result represents the intended installation.
Match optical records to the acceptance objective. Where behavior during the test matters, agree monitoring and criteria beforehand. A post-test measurement does not automatically answer a question about the exposure interval. This is procurement guidance, not a universal sampling-frequency requirement.
Procurement FAQ
- Does IP68 include vibration? Do not infer it from an IP label.
- Can sinusoidal evidence replace random testing? Not automatically.
- Must fixtures be recorded? They provide essential configuration context.
- Is final insertion loss sufficient? Check whether in-test behavior is required.
- Can changed routing inherit the result? Review the installation differences first.
