FOPM‑B Handheld Fiber Optical Power Meter

Description

Field fiber‑testing technicians frequently run into costly avoidable mistakes: manually selecting wrong wavelength or frequency setting causes distorted power readings, leading to failed link‑acceptance and repeated site‑visits. Manually writing down hundreds of test‑results on‑site consumes enormous time and easily introduces human‑recording errors for construction‑project documentation.

FOPM‑B handheld fiber optical power‑meter solves these real‑world field‑pain‑points. Equipped with InGaAs detector and six factory‑calibrated wavelengths (850/1300/1310/1490/1550/1625nm). Its unique Wave‑ID and Frequency‑ID function automatically identifies incoming optical‑signal wavelength and modulated‑frequency, removing the risk of wrong manual‑configuration and unreliable measurement results.

Built‑in data‑logger stores maximum 1000 groups of field‑test records. Via USB interface you can export saved data onto PC, greatly simplifying project‑acceptance‑report preparation for contractors and third‑party inspection teams. User self‑calibration function allows operators to complete calibration work on‑site, eliminating downtime caused by sending instruments back‑to‑factory for regular calibration.

Two model variants satisfy distinct test‑scenarios: FOPM‑7006B with ‑70~+6dBm range for standard FTTx access‑network; FOPM‑5026B of ‑50~+26dBm is tailored for high‑power CATV/HFC signal‑measurement.

Dual‑power‑supply supports 3×AA batteries for outdoor pole‑climbing and manhole field‑jobs; 8.4V external‑adapter enables non‑stop long‑time running for production‑line QC and laboratory‑calibration. Compatible with FC/SC/ST connectors, back‑lit display adapts for dim cabinet and underground working‑conditions.

It works perfectly paired with FOLS‑B fiber‑optical light‑source for complete fiber‑link insertion‑loss measurement. Widely adopted for FTTx deployment, CATV troubleshooting, central‑office patch‑cord verification, data‑center cabling inspection and technician training.

FAQ

Q1: What core advantage does Wave‑ID & Frequency‑ID bring for field‑technicians?
A: Wave‑ID auto‑detects incoming wavelength; Frequency‑ID identifies 270/330/1k/2kHz modulated‑signal. It avoids measurement‑error caused by human wrong manual‑wavelength‑setting, prevents invalid test‑data and repeated site‑visits.

Q2: How should I select between FOPM‑7006B and FOPM‑5026B?
A: Select FOPM‑7006B (−70~+6dBm) for general FTTx / access‑network power‑measurement. Choose FOPM‑5026B (−50~+26dBm) for CATV/HFC high‑optical‑power‑signal‑testing scenarios.

Q3: What is the usage of built‑in 1000‑record data‑logging & USB export?
A: Field technicians can save on‑site test‑readings inside the meter, export data via USB to PC. It eliminates error‑prone manual paper‑note‑taking and speeds‑up project‑acceptance‑report compiling for contractors and inspection‑organizations.

Q4: What does user self‑calibration mean? Do I need send unit back‑to‑factory for calibration?
A: FOPM‑B supports on‑site user self‑calibration. Under qualified reference‑condition you can finish calibration locally, reducing instrument‑downtime caused by factory‑return‑calibration.

Q5: Can FOPM‑B test fiber‑link insertion‑loss alone?
A: No. To complete end‑to‑end insertion‑loss test you need pair it with FOLS‑B stable fiber‑optical light‑source.

Q6: Two power‑supply modes, what are respective application‑scenarios?
A: Install AA batteries for outdoor pole‑climbing, manhole and field‑maintenance. Connect 8.4V external adapter for long‑time non‑stop running on production‑line or inside laboratory.

Q7: Can custom‑connectors and OEM private‑label be supported?
A: Yes, custom‑connector adapters and OEM private‑label service are available on request.
