Fluke Networks FiberLert Detector

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 Detector 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.

Key features

  • Detects optical power in SM and MM fiber (850 to 1625 nm)
  • No setup or interpretation Ð light and sound indicate signal
  • ÒNon-contactÓ detector reduces risk of contamination and damage
  • Suitable for ports and patch cords, SM, MM, UPC and APC
  • LightBeat feature indicates operation and battery status

Operating PrincipleFiberLert is a live fiber detector that senses near infrared light emitted from fiber optic cabling. A continuous red glow at the handle and an audible beeping noise (if not switched off) indicates the presence of near infrared light.
