Description
FOPM‑A Series Fiber Optical Power Meter
— Large Φ1.0mm InGaAs Detector
Standard Connector-FC/SC/ST
Field fiber‑optic technicians often suffer unstable floating readings caused by imperfect fiber‑connector alignment. Conventional small‑size detector power meters require extremely precise connector positioning; minor offset brings measurement drift and repeated readjustment, reducing work efficiency.
FOPM‑A series handheld fiber optical power meter solves this real‑world pain‑point by adopting large Φ1.0‑mm InGaAs detector. Larger receiving area greatly reduces alignment‑sensitivity and keeps test‑data stable even under non‑ideal field‑site connector mating conditions.
Two independent variants cover different application scenarios: FOPM‑7010A provides ‑70~+10dBm wide low‑power range for standard FTTx / access‑network testing; FOPM‑5026A features ‑50~+26dBm high‑power range specially adapted for CATV high‑signal‑level measurement.
It supports user‑operated self‑calibration function, technicians can complete calibration on‑site without sending instrument back‑to‑factory. 0.01dBm high‑resolution display ensures fine power‑level observation. Backlit display adapts for dark cabinet or manhole environment; 10‑minute auto‑shutdown prevents accidental power‑waste. Up to 140‑hours long battery runtime supports continuous field‑shift work.
Dual‑power‑supply architecture accepts standard AA batteries for outdoor field deployment, or 5V external AC adapter for non‑stop production‑line and laboratory long‑time measurement. Compact ergonomic handheld form‑factor suits long‑time hand‑holding operation.
This instrument is widely adopted for telecom construction, network maintenance, CATV inspection, production‑line quality‑control, optical‑component R&D and lab calibration.

FAQ
Q1: What is the main advantage of Φ1.0mm large‑size detector compared with ordinary small‑detector power meters?
A: Larger receiving‑area reduces fiber‑connector alignment‑sensitivity. Even with minor connector offset in field‑site environment, it maintains stable readings and avoids floating jumpy measurement values.
Q2: How should I choose between FOPM‑7010A and FOPM‑5026A?
A: Choose FOPM‑7010A (‑70~+10dBm) for regular FTTx and access‑network testing. Select FOPM‑5026A (‑50~+26dBm) for CATV high‑optical‑power signal measurement scenarios.
Q3: What does user self‑calibration mean? Do I need factory‑return for calibration?
A: This device supports on‑site user self‑calibration operation. You can finish calibration in‑field, no need to send instrument back to factory for routine calibration work.
Q4: What are the two power‑supply modes used for respectively?
A: Install AA batteries for outdoor field maintenance work. Connect 5V external AC adapter for non‑stop long‑time running on production‑line or inside laboratory.
Q5: Can I get custom adapters and OEM private‑label service?
A: Yes, custom connector adapters, ODM hardware modification and OEM private‑label are supported upon request.
