Fluke FI-500 FiberInspector Repair
The Fluke FI-500 FiberInspector is a fiber optic test instrument – it measures optical loss, and in the OTDR models locates faults along the fiber by timing backscattered light. Everything depends on the optical ports being clean and undamaged, because a contaminated endface changes the measurement before any electronics are involved.
June Company repairs and calibrates the Fluke FI-500 FiberInspector for fiber optic installers, network engineers, data centre technicians, and telecommunications crews. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Fluke FI-500 FiberInspector problems we fix
- Output or measurement drifted out of tolerance – corrected and verified against reference standards.
- Display, keypad or interface faults.
- Battery, charging or power faults.
- Optical port contaminated or damaged – the endface itself – the commonest cause of results that look like a bad link when the link is fine.
- Laser source output degraded or unstable.
- Detector calibration drifted.
- OTDR launch or dead-zone performance degraded.
- Connector adapters worn.
FAQs
Do you service instruments past manufacturer support? Yes. Much of what we repair is out of support, which is exactly where component-level work earns its keep.
Every fiber I test now reads high loss. Instrument or my fibers? Almost always the instrument’s optical port. Contamination or endface damage adds loss to every single measurement, which is the giveaway.
Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
