LFD‑300B / TG‑300B FiberFinder Overview
The LFD‑300B / TG‑300B FiberFinder is a handheld fiber optic tool designed to quickly locate and identify both live and dark fibers in single-mode and multi-mode networks. With audible and visual indicators, it helps technicians trace fiber routes, detect faults, and verify fiber connections without disrupting service.
This device is ideal for field technicians, network installers, and maintenance personnel. It provides fast, reliable fiber identification and troubleshooting while minimizing downtime and avoiding signal interruptions.
Features
- Non-intrusive detection of live and dark fibers without disconnecting the network.
- Supports tone generation and detection at 270Hz, 1kHz, and 2kHz.
- Audible and visual indicators for quick fiber identification.
- Compatible with single-mode and multi-mode fiber networks.
- Compact, lightweight, and portable for field use.
- Durable construction suitable for network installation and troubleshooting environments.
Benefits
- Quickly identifies active fibers and avoids accidental disconnections.
- Reduces troubleshooting time and improves network maintenance efficiency.
- Portable and easy to use in field or lab environments.
- Minimizes errors during fiber installation, testing, and repair.
Applications
- Locating live and dark fibers in telecommunication networks.
- Network installation, maintenance, and troubleshooting.
- Tracing fiber routes and identifying fiber faults.
- Testing single-mode and multi-mode fiber links in FTTH, FTTx, LAN, and WAN networks.
- Verifying fiber continuity and tone signaling during installation and repairs.
