The EXFO FPM-300 is a handheld optical power meter designed for testing passive optical networks (PONs) and general fibre optic installations. The FPM-302 variant features a standard Germanium (Ge) detector port and is FTTx ready, supporting measurements at 1310 nm, 1490 nm and 1550 nm — the three wavelengths recommended by the ITU-T (G.983.3) for PON deployments.

The FPM-300 is part of EXFO's handheld test family, which also includes the FLS-300 Light Source and the FOT-300 Optical Loss Test Set. When paired with these units, it supports auto-wavelength recognition via a digital encrypted protocol, allowing the power meter to automatically select the correct calibration parameters without manual communication between technicians. Signal encryption also enables distant referencing, transmitting reference power information to the receiving end across long distances.

Thanks to its unique design, the FPM-300 eliminates the need for offset nulling in typical measurement scenarios, reducing test time in the field.

Key Features:
- FTTx/PON ready at 1310 nm, 1490 nm and 1550 nm
- Auto-wavelength recognition with compatible EXFO sources
- Distant referencing via encrypted signal
- No offset nulling required
- Zero warm-up time
- Up to 300 hours battery life (typical)
- 3-year recommended calibration interval
- ISO 9001 certified manufacturing
