Live Fiber Detector — LFD-200
Brand: EXFO

The LFD-200 Live Fiber Detector allows you to accurately detect traffic and measures signals anywhere on singlemode and multimode fibers without having to disconnect them. Check for signal presence before rerouting or maintenance, perform continuity tests and check cable labeling. Based on non-destructive macrobending technology, this compact live fiber detector does not disrupt traffic, nor damage or overstress the fiber, enabling efficient, accurate and reliable data acquisition.

Simple Testing of Multiple Fiber Types

EXFO’s LFD-200 is the only instrument of its kind on the market that comes with a choice of three built-in, interchangeable adapter heads, making it an all-in-one solution for live fiber detection. The handle’s storage compartment holds the extra adapter heads for simple conversion and easy testing of various fiber types.

The LFD-200 also features a unique Hold button that enables hands-free operation. Just push up the button and click it down. You are now free to operate your setup.

Fast, Complete Diagnosis

Simply clamp the LFD-200 onto a fiber, listen for a beep indicating the presence of traffic, then view a complete status report on the multifunction LED display: signal presence or absence (live or dark fiber), signal type (customer traffic, continuous or modulated test signal at 270 Hz, 1 kHz or 2 kHz), signal direction, core power within 2 dB (typical), etc.
