Product information

Description

The FLUKE Live Fiber Detector FIBERLERT-125 provides a compact, non-intrusive method to detect active optical signals on fiber links and warn technicians with clear visual and audible alerts. Designed for field use, the device identifies live fibers without interrupting service, allowing safe verification and rapid troubleshooting in data centers, telecom closets, and outside plant environments. The detector supports both single-mode and multimode fiber inspection and is intended to be used inline or adjacent to connector endfaces to indicate the presence of an optical transmission.

Advantages

The FIBERLERT-125 delivers immediate visual LED indication and an audible tone when it senses an active optical signal, enabling fast identification of live fibers during maintenance and installation. Its handheld form factor and passive operation remove the need to power down systems or disconnect links, reducing downtime and the risk of service disruption. The unit’s sensitivity allows detection across common data and telecom wavelengths, helping to prevent accidental splicing or connection of live circuits.

Suitable for

  • Field technicians performing fibre network troubleshooting and verification
  • Data center maintenance and port identification tasks
  • Installation checks to avoid connecting to live optical links
  • Outside plant and premises cabling inspections

Key specifications

  • Detection method: visual LED indicator and audible alarm for live optical signals
  • Supported fiber types: single-mode and multimode
  • Wavelength sensitivity: covers common telecom and data wavelengths used in active links
  • Form factor: handheld, portable design for on-site use
  • Operation: non-intrusive detection without disconnecting service

How to use

Place the FIBERLERT-125 near the connector endface or along the fiber connector interface area where you suspect an active signal. Observe the LED indicators and listen for an audible tone; a steady or pulsed LED and audible alert indicate a live optical signal. The device requires no special setup—simply position it appropriately and interpret the visual and audible cues. Follow normal safety practices for working around active fiber systems and avoid looking directly into fiber ends.

Usage recommendations

Use the detector as a first step in verification before performing splicing, connector changes, or any work that could contact fiber links. Combine FIBERLERT-125 detection with additional tests (e.g., power meters or OTDR measurements) when precise signal level or distance information is required. Store the unit in a protective case when not in use and inspect connectors and adapter interfaces for contamination before testing to ensure reliable detection.
