Certification Information
F.C.C. Information
Electronic test equipment is exempt from Part 15 compliance (FCC) in the United
States. However, compliance verification tests are systematically performed on
most EXFO equipment.
Information
Electronic test equipment is subject to the EMC Directive in the European Union.
The EN61326 standard prescribes both emission and immunity requirements for
laboratory, measurement, and control equipment. This unit has undergone
extensive testing according to the European Union Directive and Standards.

Introducing the TG-300B/LFD-300B FiberFinder 1
1 Introducing the
TG-300B/LFD-300B
FiberFinder
The FiberFinder detects traffic and measures optical signals transmitted through
singlemode fibers without having to disconnect them.
It uses a proven macrobending technique, with an insertion loss of less than 1 dB,
that does not disrupt traffic allowing you to safely work on live fibers.
General Description
The status of all functions are indicated by LEDs located on the front panel of the
unit.

³Tone recognition LEDs: Indicate if a tone of 270 Hz, 1 kHz, or 2 kHz was
recognized by the LFD300B.
³Traffic LEDs: Indicate the presence and direction of the traffic as follows:
³When the Traffic LED on the left-hand side is lit, the traffic is coming from
the right.
³When the Traffic LED on the right-hand side is lit, the traffic is coming from
the left.
³Fiber Finder LED: Indicates if the low-frequency modulation (specific to the
TG300B) was detected by the LFD300B.
³Fiber Modulator LED: Indicates if the low-frequency modulation was emitted by
the TG300B.
³Positioning LED: Blinks while the clamping mechanism presses on the fiber.
³ON/OFF and battery status LED: Is constantly lit while the unit is running and
blinking when the batteries are low.

The switch and the display are located on the front of the unit. The battery
compartment is located on the back panel and the connection for the AC adapter is
at the bottom.
IMPORTANT
When you are not using your unit, put the switch in the upward
position to avoid premature wear of the clamping mechanism.
Switch: Clamps the fiber
under test in place and
turns on the unit.

Power Sources
The unit operates with the following power sources:
³AC adapter (connected to standard power outlet—indoor use only)
³Four alkaline AA batteries or rechargeable batteries.
Typical Applications
You can use your FiberFinder to:
³Locate a live fiber.
³Locate a dark fiber.
³Determine if a fiber is live or dark.
³Identify traffic direction on a live fiber.
Conventions
Before using the product described in this manual, you should understand the
following conventions:
WARNING
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury. Do not proceed unless you
understand and meet the required conditions.

2 Operating the
TG-300B/LFD-300B
FiberFinder
You can identify live or dark fibers using the TG-300B as the transmitter and the
LFD-300B as the receiver. You can also determine if a fiber is live or dark using the
LFD300B.
CAUTION
Do not use your units with fibers of which diameters are smaller
than 900 μm as the pressure could damage them.
IMPORTANT
Depending on the fiber type, the color, and the rubber jacket
stiffness, the test results may be very different from the ones
presented in this guide.
