Optical Power Meter – 4-in-1 Fiber Optic Tool with VFL, RJ45 Tester & LED Light – Rechargeable Fiber Light Meter for 800–1700nm Signal Testing – Network Maintenance Device
- 【4-in-1 Optical Fiber Tool for Field Technicians】- The Karvinger KPMOY9 combines four essential functions in one device: an optical power meter, a 650nm Visual Fault Locator (VFL), an RJ45 cable tester, and a built-in LED inspection light. Designed for fiber optic installers, technicians, and network engineers, it provides a compact, rugged, and portable solution for professional use in the field or on-site testing.
- 【High-Precision Optical Power Measurement】- Measure absolute and relative optical power across a wide wavelength range of 800–1700 nm using a sensitive InGaAs detector. Displays results in dBm and mW or nW, with 0.01 dB resolution. Easily switch between units and use the REF function to set a 0 dB reference. Ideal for accurate testing of fiber signal strength in live fiber optic installations or maintenance operations.
- 【RJ45 Cable Testing for Network Diagnosis】- The integrated RJ45 tester allows you to verify Ethernet cable continuity and wiring directly from the device without additional tools. Detect miswiring or open pairs in network cables quickly and efficiently. A must-have feature for field engineers performing hybrid fiber and copper network maintenance or testing LAN and telecom infrastructure.
- 【VFL + LED Work Light Built-In】- Easily detect fiber breaks, sharp bends, and continuity issues with the integrated 10km 650nm VFL in continuous or flashing mode. The powerful built-in LED light assists technicians in low-light environments, cabinets, or underground installations. A perfect companion for precise fiber inspection and troubleshooting even in challenging working conditions.
- 【Rechargeable Battery + Auto Shutdown Feature】- Powered by a rechargeable lithium battery with up to 20 hours of runtime and USB charging support. The smart 10-minute auto shutdown saves energy during idle periods. Compatible with SC, FC, and ST connectors, and built to withstand demanding conditions. The KPMOY9 is an all-in-one fiber optic and cable test tool engineered for performance and portability.

The KPMOY9 combines an optical power meter, a 650nm visual fault locator, an RJ45 cable tester, and an LED work light in a single rugged handheld unit. Carry less gear, move faster on every call, fiber and copper, handled with one tool.
4-in-1 Kit
Optical Power Meter
Reads absolute and relative optical power from 800–1700nm at 0.01 dB resolution. A sensitive InGaAs detector delivers precise, repeatable readings, with dBm / mW / dB switching and a 0 dB reference for consistent testing.
650nm Visual Fault Locator
A bright 10mW red light traces breaks, sharp bends, and macrobends, and confirms continuity on both singlemode and multimode fiber.
RJ45 Cable Tester
A full wiremap instantly flags broken terminations, mismatched pairs, and ghost connections on Ethernet runs : far more than a blinking-light tester.
LED Work Light
A built-in LED lights up dark closures, handholes, and cabinets, so you can read connectors and work without a third hand.
Accurate Readings, All-Day Endurance
Precision You Can Trust
A sensitive InGaAs detector reads live fiber confidently across 800–1700nm at 0.01 dB resolution, with easy dBm / mW / dB switching and a 0 dB reference for repeatable results.
Built to Take a Beating
A high-impact ABS shell with a rubber grip shrugs off knocks in a tool bag or on site, so it holds up job after job in real field conditions.
All-Day Runtime
Up to 20 hours on a single charge, rechargeable over USB-C from a wall plug, laptop, or power bank. No disposable batteries to chase down.
