Quality & Testing

Every assembly is 100% tested for insertion loss and return loss. You get real data per fiber, spec sheets, and the certifications your project needs — no trust-us marketing copy.

Our QC process

Documented, repeatable, and applied to every assembly that leaves the floor.

  1. 01

    Incoming inspection

    Cable, connectors, and sub-components arrive under inspection. Lots that don't meet spec are quarantined and returned to the supplier.

  2. 02

    Endface inspection

    Every endface is inspected under a 400× microscope against the IEC 61300-3-35 pass/fail zones. Fails are re-polished on the bench before test.

  3. 03

    IL/RL measurement

    Insertion loss and return loss measured on calibrated benchtop meters. Values recorded per fiber, per serial number.

  4. 04

    Continuity & polarity

    Continuity and polarity verified end-to-end. MPO channels checked against the ordered method (A/B/C) — no surprises at install.

  5. 05

    Extended testing (optional)

    OTDR traces available on request for long-haul builds. We can also perform tier-1 or tier-2 certification for turnkey handoff.

  6. 06

    Test documentation

    Every assembly ships with a test summary. Full per-fiber data is available on request and archived to the serial number.

Loss specs by grade

Published insertion loss and return loss guarantees. Actual measured values are typically better.

Values shown are worst-case guarantees. Per-fiber measurements are recorded and available with every assembly.

Certifications

Compliance and quality certifications

We hold or comply with the certifications required for regulated projects. Need documentation for a specific bid? Ask sales and we'll get you the current certificate.

Frequently asked

Do you really test every assembly?
Yes. Every fiber in every assembly is tested — 100%, no sampling. If it ships from our floor, it was measured and recorded.
What test data comes with my order?
A summary card ships with every assembly showing pass/fail per fiber. On request, we deliver the full per-fiber IL/RL values as a signed PDF report tied to the serial number on the label.
Which standards do you test to?
IEC 61300-3-35 for endface geometry, IEC 61300-3-4 for insertion loss, and IEC 61300-3-6 for return loss. Test equipment is on a documented calibration cycle traceable to NIST.
Can you test to a specific customer or industry standard?
Yes — send us the standard (RUS, MIL-DTL, custom) and we'll confirm compliance during the quote. We routinely build to customer-specific test criteria for regulated deployments.
