The EXFO EPM-102 is a handheld optical power meter engineered for accurate measurement of optical signal levels across fiber optic networks. Purpose-built for the 850 nm wavelength, this instrument delivers the measurement reliability field technicians and network engineers require for cable installation verification, signal attenuation analysis, and LAN/WAN network troubleshooting without premium pricing.
## Technical Specifications
Measurement range spans 10 dBm to –60 dBm, with display capability down to –65 dBm and 0.01 dB resolution. Power uncertainty is ±5 % ± 1 nW. The meter operates across six calibrated wavelengths: 850 nm, 1300 nm, 1310 nm, 1490 nm, 1550 nm, and 1625 nm, enabling multi-wavelength network diagnostics from short-reach LAN segments to long-haul and access networks.
Automatic offset nulling and reference value setting streamline field procedures. Battery autonomy reaches 300 hours on three AA cells, with optional AC adapter for sustained indoor use. Operating temperature range is –10 °C to 50 °C; storage rated to –40 °C to 70 °C in up to 95 % relative humidity (non-condensing).
## Key Features
• Universal push-pull connector interface with interchangeable connector support for multimode and singlemode fiber
• Compact handheld form factor: 185 mm H × 100 mm W × 55 mm D, weighing 0.4 kg
• Measurement units selectable in dB, dBm, or Watt
• Class 1 laser product compliant with IEC 60825-1 Amendment 2: 2001 and 21 CFR 1040.10
• EMC and FCC certifications for laboratory and field measurement environments
## Typical Applications
Fiber optic cable installation acceptance testing, signal attenuation verification during network deployment, and LAN/WAN troubleshooting. Passive optical network (PON) assessment at ITU-T G.983.3 recommended wavelengths (1310 nm, 1490 nm, 1550 nm) for FTTx infrastructure validation.
## Compatibility & Integration
Operates with both singlemode and multimode fibers. Supports PON testing across FTTx applications per ITU-T G.983.3 standards.
