LogiLink WZ0049 Fiber Checker Visual Fault Locator 10mW with 2.5 and 1.25 mm Ferrules for Single and Multimode Fiber Optic Cables

The LogiLink WZ0049 Fiber Checker Visual Fault Locator 10mW is an essential tool designed for testing and maintaining single and multimode fiber optic cables. This compact, pen-type device quickly and efficiently identifies breaks, bends, and other faults in fiber optic networks. Equipped with a 10mW output power and a range of up to 10 kilometers, it provides reliable performance for technicians and network administrators working on complex optical infrastructures.

Advantages

This visual fault locator offers exceptional precision in locating faults within glass fibers, including hard-to-find issues within OTDR dead zones. Its robust design features a durable aluminum housing that protects the internal components during daily field use. The included 1.25 mm adapter alongside the standard 2.5 mm ferrule ensures broad compatibility with various connector types. With an operating time of up to 40 hours on standard batteries, it delivers long-lasting field readiness and dependable operation without frequent battery replacements.

Suitable for

• Testing and troubleshooting single and multimode fiber optic cables
• Identifying fiber breaks, sharp bends, and micro-cracks
• End-to-end fiber identification and cable patching
• Locating faults within OTDR dead zones

When it may not be suitable

This device is designed specifically for visual fault location in optical fibers and is not suitable for measuring exact signal attenuation or testing copper network cables. It should not be used for high-power fiber optic systems that exceed the safety parameters of a Class 1 laser source.

Key specifications

• Visual fault locator for single and multimode fiber optic cables
• 10mW output power with a range of up to 10 km
• Wavelength range from 650 to 670 nm
• 2.5 mm ferrule and 1.25 mm adapter supporting FC, LC, SC, ST, LSH, and DIN connectors
• Powered by 2 AA alkaline batteries with up to 40 hours of standby time
• Dimensions: 175 mm x 30 mm x 30 mm

How to use

To use the fiber checker, insert two AA alkaline batteries into the battery compartment following the correct polarity. Remove the protective cap from the optical output and connect the fiber optic cable using the appropriate ferrule or adapter size. Press the power button to emit the red laser light into the cable. Inspect the fiber run visually to spot the red light glowing at the exact point of any break, bend, or fault.

What to consider before purchase

• Verify that your fiber optic connectors match the supported 2.5 mm or 1.25 mm ferrule types
• Ensure you have two AA alkaline batteries available, as they are not included in the package
• Confirm that your maximum cable testing distance does not exceed the 10 km operational limit

Usage recommendations: Always wear appropriate laser safety eyewear and avoid looking directly into the optical output or the connected fiber end when the device is active. Store the unit in the provided protective pouch when not in use to prevent dust accumulation on the optical components.
