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 results: no more network outages caused be inadequate fiber detection or identification, and a minimized need to access the network, helping prevent errors.
Spec sheet User manual

LFD-250B - live fiber detector

Introduces step-motor-activated bending and makes fixed-angle bending—and its drawbacks—a thing of the past.

LFD-200 - live fiber detector

Allows you to detect traffic and measure signals anywhere on singlemode fibers without having to disconnect them.
