Introducing the LFD-200 Live Fiber Detector 1
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.

Available Models
Four different models are available, as explained in the table below:
Model Description
LFD-201 Detects continuous signal or signal modulated at 270 Hz, 1 kHz,
and 2 kHz.
Comes with three interchangeable adapter heads: 250 μm,
900 μm, 3 mm.
LFD-202 Detects continuous signal or signal modulated at 270 Hz, 1 kHz,
and 2 kHz.
Displays the relative core power in the fiber (that is, between –
6dbmand–40dBm).
Comes with three interchangeable adapter heads: 250 μm,
900 μm, 3 mm.
LFD-202P Detects continuous signal or signal modulated at 270 Hz, 1 kHz,
and 2 kHz.
Displays the relative core power in the fiber (that is, between
+14dbmand–19dBm).
Comes with three interchangeable adapter heads: 250 μm,
900 μm, 3 mm.
LFD-203 Detects continuous signal or signal modulated at 270 Hz, 1 kHz,
and 2 kHz.
Especially designed for ribbon fibers.
Comes with three interchangeable adapter heads: 3 mm, bare
ribbon, jacketed ribbon.

Adapter Heads
The Live Fiber Detector comes with interchangeable adapter heads for simple
conversion and multiple fiber-type testing. The adapter heads are stored in an
internal storage compartment located at the back of the unit.
The LFD-201, LFD-202 and LFD-202P Live Fiber Detector are supplied with three
adapter heads:

Introducing the LFD-200 Live Fiber Detector 5
The LFD-203 Live Fiber Detector is supplied with three adapter heads.
The adapter heads for the LFD-203 model have an indexing notch, which is part of
the ambient-light-reduction design.
Power Source
The Live Fiber Detector is powered by a 9 V alkaline battery.
When the battery voltage becomes low, the LOW BAT LED illuminates (LFD-201 and
LFD-203 models) or Lb appears on the display (LFD-202 and LFD-202P models).
The unit will continue to operate for some time, but the battery should be replaced
with a fresh 9 V alkaline battery as soon as possible (see Replacing the 9 V Battery
on page 11).
Indexing notch
Deep-slot adapter head to be
used with a jacketed ribbon
fiber of up to 12 counts.
Shallow-slot adapter head
to be used with a bare
ribbon fiber of up to 12
counts.
Slotted adapter head to be
used with a 3 mm or a 2 mm
jacketed fiber (that is, pigtails
and jumpers) or a loose tube
fiber.
