This unit
The EXFO EPM-500 is a handheld optical power meter engineered for accurate power measurements across fiber optic networks operating at 800 nm and beyond. This field instrument delivers precise readings with reference value setting and requires no offset nulling for reliable operation in diverse test environments. When paired with an ELS-500 Light Source in Auto-Switching mode, it enables semi-automated loss measurement with automatic wavelength switching for error-free testing.
Technical Specifications
Wavelength Range: 800 nm primary; also capable at 850 nm, 1300 nm, 1310 nm, 1490 nm, 1550 nm, and 1625 nm, extending to 1650 nm maximum
Measurement Units: dB, dBm, and Watt
Detector Type: Ge or GeX
Power Source: Rechargeable battery
Laser Safety Classification: IEC 60825-1 Amendment 2:2001 and 21 CFR 1040.10; Class 1 without VCSEL sources; Class 3R with Visual Fault Locator option

Exfo EPM-500 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo EPM-500. Calibration covers detector responsivity at 850, 1310, 1490, 1550, and 1625 nm, absolute power accuracy, linearity across the full dynamic range, and reference power level. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Exfo EPM-500 faults: detector contamination, damaged FC/PC input port, display failure. Common repairs include detector port cleaning or replacement, display repair, and battery or capacitor replacement in older HP/Agilent/Keysight units.
