LFD-300B/TG-300B - Live fiber identifier/tone generator

Overview
Enables technicians to identify a specific live fiber without having to disconnect it and, above all, without having to guess. The end result: no more network outages caused by inadequate fiber detection or identification, and a minimized need to access the network, helping to prevent errors.
LFD-300B/TG-300B - Live fiber identifier/tone generator

Key features

  • Pinpoints a specific live fiber using EXFO’s FiberFinder™ functionality
  • Induces minimal loss: ≤ 1 dB
  • Locates a particular dark fiber using tone recognition (270 Hz, 1 kHz, 2 kHz)
  • Improved: faster test cycle—three times faster

Applications

  • Fiber identification
