## Summary description

Lightwin FIBERCHECKER 5MW is a fiber test light emitting at 655 nm ±10 nm with an output power of 5 mW, designed for 2.5 mm ferrules. It serves as a visual fault locator and alignment aid for fiber optic inspection, connector testing and basic continuity checks in installations and maintenance of optical networks.

## Long description

Lightwin FIBERCHECKER 5MW is a compact visual fault locator and alignment aid for optical fiber work. Emitting a visible red beam at 655 nm ±10 nm with an output power of 5 mW, this fiber test light is built for use with standard 2.5 mm ferrule connectors. It is intended for quick continuity checks, connector inspection and basic troubleshooting during installation and maintenance of optical networks.
Advantages
The device provides a clear visible red light that makes breaks, bends and poor connections in multimode and many single-mode fibers easy to identify. Its 2.5 mm ferrule compatibility simplifies testing of common SC and ST style connectors without adapters. The compact form factor and single-button operation support fast handheld use in the field or workshop environments.
Suitable for
 Quick continuity tests of optical fibers
 Visual fault location for locating breaks, sharp bends and high loss points
 Connector alignment and mating verification for 2.5 mm ferrules (e.g., SC, ST)
 Basic installation and maintenance checks in LAN and enterprise fiber runs
When it may not be suitable
This fiber test light is not intended as a precision optical power meter or for quantitative loss measurements. The visible 655 nm wavelength may not couple efficiently into some single-mode fibers designed for infrared wavelengths, so it can be less effective for long-distance single-mode fault finding. It is not a substitute for certified inspection microscopes or OTDRs when detailed diagnostic data is required.
Key specifications
 Output wavelength: 655 nm ±10 nm
 Output optical power: 5 mW
 Connector compatibility: 2.5 mm ferrule (built for SC/ST style connectors)
 Primary function: Visual fault locator / continuity tester
 Form factor: Handheld compact tester
How to use
Insert the Lightwin FIBERCHECKER 5MW into the 2.5 mm ferrule connector of the fiber to be tested, or use an appropriate mating sleeve where required. Power the unit on with the control switch; the red laser/LED will emit a continuous visible beam. Observe the far end of the fiber or inspect along the cable for bright light leakage, bends or breaks indicating faults. Turn the device off after testing and store it in a protective sleeve to avoid damage to the emitter and connector tip.
What to consider before purchase
 Ensure your fiber connectors are 2.5 mm ferrule types (SC, ST) or that you have suitable adapters for smaller/larger ferrules.
 Recognize that 655 nm visible light is suited for visual checks but not precise loss measurement or long-range single-mode testing.
 Verify that 5 mW output power and visible wavelength meet site safety policies and handling requirements.
Usage recommendations
Use the Lightwin FIBERCHECKER 5MW for short continuity checks and local fault locating in multimode installations, always follow laser safety guidelines, avoid direct eye exposure to the beam, and pair the tool with inspection scopes or power meters when quantitative measurements or certification are required.
