Fluke Networks Fibre Optic Locator Single & Multimode 1625nm Wavelength 1h Battery Life FIBERLERT-125

Fluke Networks FIBERLERT-125 Fibre Optic Locator is a handheld fibre tester designed for rapid verification of optical signal presence, polarity, and basic connectivity in single-mode and multimode fibre optic networks. It operates at a wavelength of 1625 nm and provides approximately 1 hour of battery life powered by two AAA alkaline batteries.

This locator detects near-infrared light in fibre optic ports and patchcord end faces without requiring physical contact with the ferrule, preventing damage or contamination. The LightBeat™ LED combined with an audible tone offers immediate visual and audio confirmation of active links.

The device's non-contact ceramic ferrule is compatible with 1.25 mm LC receptacles and supports UPC and APC connectors, making it suitable for commissioning single- and multimode campus links, polarity checks in data centres, and fault localisation on multimode patch panels. It automatically shuts off after five minutes of inactivity to preserve battery life.

The unit tolerates environmental conditions from −10 °C to 50 °C and supports non-condensing humidity up to 95% between 10 °C and 35 °C. Its compact size (168 mm x 25 mm x 16 mm) and lightweight design (59 g) make it highly portable for field use.

The device detects wavelengths from 850 nm to 1625 nm to identify active links quickly. It measures optical power from −30 dBm to 3 dBm for basic power verification. The non-contact ceramic ferrule prevents ferrule endface contamination or damage.

LightBeat™ LED and audible tone indicate operational and battery status. An automatic shut-off after five minutes aids battery conservation. Compatible with 1.25 mm LC receptacles supporting UPC and APC connectors. Powered by two AAA alkaline batteries with approximately 1 hour battery life.

Operates in temperature range of −10 °C to 50 °C with high humidity tolerance. Lightweight and compact, facilitating easy portability. Ideal for FTTH drop port verification, data centre polarity checks, commissioning campus links, and fault localisation.

This fibre optic locator is essential for telecommunication and industrial cabling environments, facilitating quick verification and troubleshooting of optical links. It supports critical applications such as FTTH network validation, polarity verification of LC patchcords, and multimode patch panel maintenance.

For users in industrial, telecommunications, and data centre sectors, the Fluke Networks FIBERLERT-125 offers a reliable and user-friendly tool that enhances network testing efficiency.
