Product Overview

Fluke Networks FiberLert Fiber Light Detector

Key features

Detects optical power in SM and MM fiber (850 to 1625 nm)
No setup or interpretation – light and sound indicate signal
“Non-contact” detector reduces risk of contamination and damage
Suitable for ports and patch cords, SM, MM, UPC and APC
LightBeat™ indicates operation and battery status

Quickly check fiber activity, polarity, and connectivity

Just place in front of the fiber end face or port and a light and tone indicate an active fiber (850 nm to 1625 nm) - no setup or interpretation required.

This pocket-sized tool tests:

Single-mode
Multimode
UPC and APC patch cords
Ports with a non-contact / non-contaminating detector

The LightBeat™ feature flashes the LED, indicating a powered-on condition and good battery and a timer shuts FiberLert™ off after five minutes of inactivity to extend battery life (2xAAA, included). Rugged design includes a convenient pocket clip and is backed by a two-year warranty.
