This unit
The EXFO EPM-100 is a handheld optical power meter for measuring optical power in fiber optic systems at 850 nm wavelength. It delivers precise power measurements from +10 dBm down to −60 dBm with ±5% ± 10 nW uncertainty and 0.01 dB resolution. The meter supports multiple measurement units (dB, dBm, W) and features a reference function for direct loss calculations. Its universal push-pull interface accepts interchangeable connector adapters
FC, ST, SC, and LC - enabling rapid field connections. The EPM-100 runs on three AA batteries for approximately 300 hours of operation and reaches full specification accuracy after a 15-minute warm-up. Housed in a compact form factor measuring 185 mm × 100 mm × 55 mm and weighing 0.4 kg, it operates across −10 °C to 50 °C and handles 0–95% relative humidity without condensation. The meter integrates with EXFO's ELS-100 Light Source for attenuation measurements and suits LAN/WAN fiber-optic network testing and troubleshooting.

Exfo EPM-100 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo EPM-100. 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-100 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.
