Optical Power Meter with VFL & Cable Tester - Compact 4in1 Tool

In this review the Optical Power Meter with Visual Fault Locator is presented as a compact, all-in-one tester aimed at network technicians and field engineers who need fast diagnostics without packing multiple instruments. The single biggest reason to buy is its combination of an optical power meter, visual fault locator and lan cable tester in one handheld unit, which significantly reduces carry weight and speeds troubleshooting. The reviewer found the device particularly useful for routine fiber loss checks and quick continuity verification where portability and rechargeability matter.

Key Features

• 4in1 functions: Combines OPM, VFL and lan cable tester into one unit so users can run several checks without switching tools.
• Wide wavelength support: Measures SM and MM fiber across nine common wavelengths for realistic field compatibility with most fiber links.
• Good test range: The optical power meter covers a wide range from -70 dBm to +10 dBm which handles both lowpower and stronger sources.
• Visual fault locator: 5 mW red light with continuous and flashing modes to spot breaks, bends and poor connections quickly.
• Rechargeable convenience: Builtin 1100 mAh Liion battery and USB charging make it easy to keep powered on jobs without carrying disposable cells.
• Clear readout: LCD shows power loss, wavelength, frequency and battery status so measurements are easy to document on the spot.

Who It's For

The unit is best for field technicians, small team installers and maintenance staff who need a single handheld device to test fiber loss, locate faults and verify cable continuity in everyday installs and troubleshooting. Its portability, rechargeable battery and universal FC/SC/ST compatibility suit onsite work where speed matters.

It is less appropriate for users who require advanced OTDR trace analysis or precision lab calibration; for those deep diagnostic tasks a dedicated OTDR or laboratory power meter would be the right choice.

Pros & Cons

Pros

• Combines multiple test functions so fewer tools are needed on site.
• Accurate and reliable readings according to users, with performance comparable to pricier testers for routine work.
• Rechargeable battery, USB charging and integrated flashlight improve field usability and portability.
• Simple, easytoread LCD and automatic continuity checks speed workflow.

Cons

• VFL light function received mixed feedback from some users, so expectations should be moderate compared with dedicated visual fault locators.
• Not a replacement for OTDR level diagnostics when detailed trace analysis is required.

Specifications

Our Verdict

This compact 4in1 tester is a strong value for field technicians and small teams who need reliable fiber power readings, quick fault location and basic lan cable checks without multiple instruments. Its rechargeable battery, universal interfaces and wide wavelength support make it a practical everyday tool, though teams needing advanced OTDR analysis should look to dedicated equipment.

Frequently Asked Questions

Does it need disposable batteries?
The unit uses an internal 1100 mAh Liion battery and charges via USB, so no disposable batteries are required.

Can it locate breaks on singlemode fiber?
Yes, the VFL with 5 mW red light and continuous/flashing modes is suitable for locating breaks and tight bends on singlemode and multimode fibers.

Will it replace an OTDR?
No, this device provides useful power and fault checks for routine work but does not perform the trace analysis and detailed event characterization that an OTDR provides.
