Where selection starts
A useful RFQ does not require every parameter to be known, but it should distinguish known requirements from open items. Start with application, interfaces, quantities and schedule, then add drawings and testing needs.
- Decision to make
- Separate sample quantity from expected volume and identify whether the drawing is a discussion draft or an approved revision.
- Record to prepare
- Project brief, revision-controlled attachments and an open-items list.
Topic-specific checks
- Minimum inputs: application, end interfaces, fiber count, length, sample quantity and expected volume; mark unknowns as open questions.
- Review attachments: revision-controlled drawing, port map, mating-part information, environmental requirements, test and acceptance methods, and target delivery date.
Four-step selection check
- Define the actual interfaces and mating parts at both ends
- Record fiber type, count, channel map and polarity
- Confirm length, bend routing, breakout, jacket and environment
- Agree samples, test method, limits and data format
Evidence to request when sourcing
Request drawings, material boundaries, test methods, sample records and batch traceability that match the purchased revision. Certification marks, performance values and environmental ratings matter only when they map to a specific product revision.
