Buying Guide: Choosing The Right Power Meter Fiber Optic Tool
What should you consider when selecting a power meter? Start with wavelength coverage: most professional meters measure 850–1650 nm, but specific installations may require up to 1700 nm or more. Detector type (InGaAs is common) affects sensitivity and dynamic range. Look at display options (linear mW vs. dBm) and whether the device offers both absolute and relative power with a reference function. If you work with copper and fiber networks, an integrated RJ45 tester can save time. Finally, assess portability, battery life, and whether a VFL is included for locating faults in the same tool.
Connector compatibility matters: ensure the device supports FC, SC, ST, and LC adapters or includes the appropriate adaptors. If your work involves live networks, verify the unit supports a wide dynamic range and provides a backlit LCD for dim environments. For on-site reporting, choose meters with data storage or memory function to capture multiple readings. If you need long battery life in the field, consider devices that run on standard AA or USB-rechargeable Li-ion batteries.
Usage scenarios:
- Field installation: prefer compact 4-in-1 or 5-in-1 meters with VFL to quickly locate faults.
- Laboratories and maintenance: look for higher sensitivity, wider wavelength coverage, and easy export of test data.
- Hybrid networks: RJ45 testing capabilities help diagnose copper/fiber segments without extra tools.
