1 Introducing the LFD-200

Live Fiber Detector

Main Features

The LFD-200 Live Fiber Detector detects traffic and measures optical signals
transmitted through singlemode and multimode fibers without having to disconnect
them.

The Live Fiber Detector uses a safe macrobending technique that does not disrupt
traffic (that is, it eliminates the need to identify a fiber by opening it at the splice
point). At the same time, it avoids damaging or overstressing the fiber. You end up
with accurate and reliable information.

The Live Fiber Detector comes with interchangeable adapter heads stored right into
the unit. It also features a slider that can be locked for hands-free operation.
