• Non-intrusive power measurement and fiber identification

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.

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

EXFO’s LFD-300B / TG-300B FiberFinder: A uniquely designed live fiber identifier

For major singlemode fibers, insertion loss is a function of the bending angle. Although the angles differ, the behavior remains the same.

The LFD-300B FiberFinder brings a unique approach: the power loss is monitored as the angle is changed. Therefore, the angle is automatically optimized for each fiber type and each singlemode wavelength. This results in clear-cut advantages:

• •Maximum loss of 1 dB guaranteed for most singlemode telecom fibers (most jacket types) and any wavelength
• •No damage to the fiber: bending is always minimal, and the fiber is released when no power is detected
• •Traffic detection and direction identification a
• • In-line, non-disruptive power estimation a
• •Safe to be used in long-haul applications and on high-payload fibers—contrary to traditional live fiber detectors
• •Optimized for 900 µm, 1.6 mm and 3 mm jackets; no need to replace the headpiece

Ambient light offset – EXFO’s LFD-300B performs an ambient light offset prior to fiber bending, which makes it less sensitive to ambient light. A push-down cap can also be placed on the head-end to block intense ambient light.
