EXFO TK-FF FiberFinder Kit

Overview

The EXFO TK-FF FiberFinder Kit is an advanced fiber management solution comprised of the LFD-300 Live Fiber Detector and the TG-300 Tone Generator. This professional-grade kit is designed to pinpoint specific fibers within complex network environments, including both live and dark fiber applications, without the need to disconnect fibers or disrupt active traffic.

Utilizing proprietary FiberFinder technology, the kit induces minimal optical loss (guaranteed 1 dB maximum) while maintaining signal integrity. It is an ideal tool for data center operators and network engineers performing network upgrades or maintenance, where identifying the correct fiber accurately is critical to preventing service outages and avoiding human error.

The system automatically optimizes the bending angle for different fiber types and wavelengths, ensuring reliable traffic detection and tone recognition. Housed in a durable construction, the kit is suitable for use in diverse operating environments, from long-haul outside plant applications to high-density payload fibers in data centers.

Key Features

• Non-Intrusive Identification
  Enables identification of live fibers without requiring disconnection, preventing network service outages.
• FiberFinder Technology
  Allows precise pinpointing of a specific live fiber by pairing the LFD-300 detector with the TG-300 signature tone generator.
• Minimal Insertion Loss
  Induces a maximum of 1 dB loss during testing, ensuring performance remains within acceptable tolerances for most single-mode systems.
• Automatic Angle Optimization
  The LFD-300 monitors power loss while automatically adjusting the bending angle to suit various fiber types and operating wavelengths.
• Ambient Light Offset
  Performs offset adjustments prior to fiber bending to ensure accurate detection even in high-ambient-light environments.
• Multiple Tone Recognition
  Supports detection of 270-Hz, 1-kHz, and 2-kHz tones, allowing for effective dark fiber identification.
• Non-Destructive Testing
  Designed to release the fiber immediately when no power is detected, ensuring no physical damage to the fiber cable.
