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.

Tone recognition

³ Tone recognition LEDs: Indicate if a tone of 270 Hz, 1 kHz, or 2 kHz was

recognized by the LFD300B.

³ Traffic LEDs: Indicate the presence and direction of the traffic as follows:

³ When the Traffic LED on the left-hand side is lit, the traffic is coming from

the right.

³ When the Traffic LED on the right-hand side is lit, the traffic is coming from

the left.

³ Fiber Finder LED: Indicates if the low-frequency modulation (specific to the

TG300B) was detected by the LFD300B.

³ Fiber Modulator LED: Indicates if the low-frequency modulation was emitted by

the TG300B.

³ Positioning LED: Blinks while the clamping mechanism presses on the fiber.

³ ON/OFF and battery status LED: Is constantly lit while the unit is running and

blinking when the batteries are low.

Introducing the TG-300B/LFD-300B FiberFinder 3

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.

Protective cap: Reduces the influence that

ambient light might have on test results.

IMPORTANT

When you are not using your unit, put the switch in the upward
position to avoid premature wear of the clamping mechanism.

Power Sources

The unit operates with the following power sources:

³ AC adapter (connected to standard power outlet—indoor use only)

³ Four alkaline AA batteries or rechargeable batteries.

Typical Applications

You can use your FiberFinder to:

³ Locate a live fiber.

³ Locate a dark fiber.

³ Determine if a fiber is live or dark.

³ Identify traffic direction on a live fiber.
