Description
Fluke CertiFiber Repair
The Fluke Networks CertiFiber is a fiber-optic loss test set — it certifies fiber cabling by measuring optical loss and length (with a paired light source and power meter) to standard, for installers certifying fiber networks. As a field-carried optical instrument, its faults concentrate in the optical source and detector, the optical connectors/ports, the display, and the battery.
FlukeMeterRepair.com repairs and calibrates the Fluke CertiFiber for fiber installers and network test teams.
Common Fluke CertiFiber problems we fix
- Autotest / loss measurement faults — the autotest or optical-loss measurement returning wrong results, repaired and recalibrated against optical standards.

- Optical-connector / port faults — a contaminated or damaged optical port, serviced.
- Display or interface faults — repaired.
- Won’t power on or hold a charge — battery/power faults.
FAQs
My CertiFiber loss results are off — fixable? Yes. Source, detector, and port faults are repairable and recalibrated so fiber certification is accurate, with documented results. (Send both units if it’s a paired set.)
Is the optical reference verified? Yes — power and wavelength are checked against our optical standards.
Every repair includes calibration verification and a 90-day parts-and-labor warranty. Email us or request service.
