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

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.

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

Non-intrusive power measurement and fiber identification

Description

Pinpointing live and dark fibers: guesswork ends here

Performing network upgrade or optical testing requires a fiber to be disconnected. This is often easier said than done, since finding the right connection can be tricky, namely because of fiber mislabeling or poor record keeping. While the dark fiber can be identified using a tone generator (270 Hz, 1 kHz, 2 kHz), the live fiber identification technique often involves one technician pulling one end of the patchcord, with another technician trying to identify which patchcord is moving at the other end—a process that translates into long delays and can result in unnecessary service disruption.

Combined with the TG-300B Tone Generator, the innovative LFD-300B FiberFinder™ Live Fiber Identifier enables technicians to identify a specific live fiber without having to disconnect it and, above all, without having to guess.

This brings key benefits:

  • No more network outages as a result of fiber detection/identification procedures
  • The minimized need to access the network helps prevent errors
