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.

Operating the Live Fiber Detector 7
2 Operating the Live Fiber
Detector
To operate the Live Fiber Detector:
1. Choose an adapter head for the type of fiber to be tested (see Adapter Heads on
page 4).
2. Slide the adapter head into the mating slotted channel, applying a slight
downward pressure.
If you have the LFD-203 Live Fiber Detector model, be sure to place the adapter
with the indexing notch facing the front of the unit.
3. Place the fiber gently in the alignment groove of the adapter head.
4. Slide the switch upward.
OR
For hands-free operation, slide the switch upward and over to the right to lock it
in place.
Note: Each time the switch is operated, the Live Fiber Detector performs a
self-test. During the self-test, all LEDs will illuminate and will turn off
after approximately 0.5 seconds.
5. If you want to send a modulated signal, connect the unit to a source (such as

Note: The recommended wavelength is 1550 nm for tone identification. If you
use another wavelength than 1310 nm or 1550 nm, the Live Fiber
Detector will still detect the signal, but the specifications are not
guaranteed.
6. Evaluate the presence and direction of light transmission.
If the traffic LED indicator located on the left-hand side is illuminated, the
traffic is coming from the right.
If the traffic LED indicator located on the right-hand side is illuminated, the
traffic is coming from the left.
A beep also indicates the presence of traffic.
7. Identify the tone.
If you have connected a source to send a modulated signal, one of the 270 Hz,
1Hz, or 2kHz tone LED indicator will be illuminated.
Note: During the operation at the lowest levels of tone detection
(approximately –40 dB core power), the tone LEDs may flicker, which
indicates that the minimum range of detection was reached.

3 Maintenance
To help ensure long, trouble-free operation:
Always inspect fiber-optic connectors before using them and clean them if
necessary.
Keep the unit free of dust.
Clean the unit casing and front panel with a cloth slightly dampened with water.
Store unit at room temperature in a clean and dry area. Keep the unit out of
direct sunlight.
Avoid high humidity or significant temperature fluctuations.
Avoid unnecessary shocks and vibrations.
If any liquids are spilled on or into the unit, turn off the power immediately,
disconnect from any external power source, remove the batteries and let the
unit dry completely.
WARNING
Use of controls, adjustments, and procedures for operation and
maintenance other than those specified herein may result in
hazardous radiation exposure.
To clean detector ports:
1. If the detector is dusty, blow dry with compressed air.
2. Being careful not to touch the soft end of the swab, moisten a cleaning tip with
only one drop of isopropyl alcohol.
IMPORTANT
Alcohol may leave traces if used abundantly. Do not use bottles that
distribute too much alcohol at a time.
3. While applying light pressure (to avoid breaking the detector window), gently
rotate the cleaning tip on the detector window.
4. Repeat step 3 with a dr y cleaning tip or blow dr y with compressed air.
5. Discard the cleaning tips after one use.

Maintenance 11
Replacing the 9 V 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.
To replace the 9 V battery:
1. Turn off the Live Fiber Detector.
2. Open the battery compartment door located at the front of the unit.
3. Change the 9 V batter y, respecting the polarity.
4. Close the battery compartment door.
Adjusting Compartment and Battery Doors
3 4
With time and handling, the adapter head compartment door, as well as the battery
door may require adjustment to ensure the proper operation of your Live Fiber
Detector.
To adjust the door(s):
1. Open the door you want to adjust by pressing on it and sliding it away from the
Live Fiber Detector.
2. Locate the adjustment screw.
3. With a flat-head screwdriver, press down on the small silver ball until the head
of the screwdriver fits into the small grooves on each side of the screw.
Note: You must press down on the silver ball to be able to turn the screw.
4. Turn the screw clockwise or counterclockwise, on whether you want to slacken
or tighten the screw.
5. Close the door.
