Fiber Testing
Diagnostic fiber testing and fault-finding for new and existing links — insertion loss, OTDR, and endface inspection performed, results documented, and faults located.
We test fiber links to verify performance and isolate faults, whether you're commissioning new runs or chasing an intermittent link in production. Crews run insertion-loss and continuity checks with an optical loss test set, use an OTDR to locate breaks, high-loss splices, sharp bends, and dirty connectors by distance, and inspect endfaces to IEC 61300-3-35 with a scope before mating. We confirm correct polarity on duplex and MPO/MTP links and validate that measured loss fits the optics' budget. You get a clear test report with measured values and OTDR traces, plus a list of any faults found and the corrective action, so the link is documented and trusted before it carries traffic.
What's included
- Insertion-loss and continuity testing with an optical loss test set
- OTDR fault location of breaks, high-loss splices, bends, and bad connectors
- Endface inspection and cleaning to IEC 61300-3-35
- Polarity verification on duplex and MPO/MTP links
- Loss-budget validation against the deployed optics and distance
- Re-test after corrective repairs or re-termination
Deliverables
- Test report with measured insertion loss and continuity per strand
- OTDR traces with fault locations identified by distance
- Fault and corrective-action summary with post-repair re-test results
Frequently asked
Can you find the exact location of a fiber break?
Yes — an OTDR measures the distance to a break, high-loss splice, or sharp bend along the strand, so we can pinpoint it rather than guess. We correlate that distance against the as-built run to direct repair crews straight to the affected section.
How is fiber testing different from certification?
Testing is about verifying performance and diagnosing faults; certification is a formal pass/fail against a standard's loss budget with calibrated, archived results. Many links only need testing, but if you want a manufacturer warranty or formal acceptance, you'll want certification — we offer both.
Our link works but throws errors — can testing help?
Often yes. Intermittent errors frequently trace back to a dirty or marginal connector, a borderline splice, or a link running too close to its loss budget. We inspect endfaces, measure insertion loss, and OTDR the run to find the marginal component and confirm the fix with a re-test.
