OFI-BI
NOTE
External light detecting function
When external light such as sunlight is detected, both sides of the direction
indicator will turn on simultaneously. In case the external light is strong,
identifier function will not perform properly, so please cover the plunger
portion by hand and this will solve the problem.
Please refer to Page 25 for details.
ONU detecting function
When you see the message “Require optimization for use in your region”
or don’t find appropriate settings after accessing the “ONU Setup” menu,
this means the function is not activated yet in your region. After obtaining
the ONU signal in your region, AFL will release a firmware upgrade to
activate the function for the OFI-BI. Please consult your local AFL
distributor for more information.

This may result in equipment failure.
Do not place heavy weight on the Identifier. This may result in equipment failure,
electric shock and fire.
Remove the batteries from the equipment when not using it for a long time.
Keeping the batteries in the equipment may cause the batteries to leak and
damage the equipment.
Do not recharge a non-rechargeable battery, e.g. a dry-cell battery.
This may cause heat, leakage or rupture of the unit and injury.
Use the appropriate battery charger specified by the battery manufacturer. Using a
charger not specified by the manufacturer could cause injury or fire.
The equipment must be repaired or adjusted by a qualified technician or engineer.
Incorrect repair may cause fire or electric shock. Should any problems arise,
please contact your distributor.
Perform fall preventive measures, such as attaching a strap, when working at
height. Dropping may cause damage of the equipment and personal injury.
Do not press on the LCD panel with sharp materials.
It may cause damage to the LCD.

Description
1 ． Outline of Identifier Operation
Optical identification is a method of detecting signals in an optical fiber without
cutting the fiber.
The tone signal light source is connected to one end of an optical fiber to be monitored
and incidence of the light is carried along the fiber. At the working place, the OFI-BI
clamps the relevant optical fiber and light signals propagate from the bend and are
detected by sensors within the OFI-BI.
When any signal or light is detected on the clamped optical fiber, the OFI-BI lets the
user know by a buzzer sound and illuminate the related LED dependent on the light
signal detected. When no signal and light is detected, it lets the user know by
illuminating the “NO SIGNAL” LED.
In addition, when the OFI-BI detects the light signal, the estimated optical power in
the optical fiber is displayed on the LCD panel.
Please use 1310nm / 1550nm / 1650nm and 270Hz / 1kHz / 2kHz light as a tone
signal.

1 ． Cleaning the Optical Detector
If the optical detectors are dirty, the OFI-BI
cannot detect the leaking light signals from the
bent optical fiber. so please ensure to check
that there is no dirt on the detector before using
the OFI-BI.
How to Clean the Detector
Clean the optical detector with an
alcohol-moistened thin cotton swab. Remove
excess alcohol from the optical detector with
a clean dry swab.
Remove the plunger if it is difficult to clean the detector since the gap between
the detectors and the plunger is narrow.
2 ． Attach or Remove the Plunger
How to Remove the Plunger
(1) Hold both sides of the plunger cover and pull it out by tilting it slightly.
(2) Pull the plunger up vertically.
How to Attach the Plunger
(1) Put the plunger down onto the two retaining pins.
(2) Hold both sides of the plunger cover and set its ends to the groove of the OFI-BI
body. Then push it in till it clicks.
Pulling the trigger makes it easier to remove or attach the plunger cover.

3 ． Zeroing
It is necessary to perform the zeroing function at the following case;
1) Every day before using the OFI-BI
2) There is big change of ambient temperature
3) If has been changed the detection setting
4) Before measuring a faint signal using FINE mode
Operation Procedure
(1) Pull the trigger without clamping any optical fiber. The identifier function starts
automatically.
(2) Keep pulling the trigger and press the
ZERO key to start the zeroing
function. Do not release the trigger
until “ZEROING” disappears.
(3) The zeroing function finishes after a few seconds. If there is no error, the OFI-BI
beeps 1 time and shows “- - -”(Under Range). If an error occurs, the OFI-BI
beeps 3 times and shows “-E1-” that blinks intermittently. To quit from the error
indication, press the ZERO key again.
Now Zeroing (indicator blinks)
Error (Beep 3 times)
No Error (Beep 1 time)
Since the OFI-BI keeps the calibration data in the non-volatile internal
memory it is not necessary to perform the zeroing function otherwise noted
above.

17
Identifier Function
If the panel shows “-E1-“, confirm the following:
If the surrounding is brightly lit, cover the optical detector and retry the zeroing
function.
If the optical detector is covered, turn the Identifier power off and retry the
zeroing function.
4 ． Signal Selection
Detectable signals are 270Hz, 1 kHz, 2 kHz, Traffic (CW) and ONU.
Different combinations of signal types can be selected in Identifier Setup menus.
* Default : 270Hz,1kHz,2kHz and Traffic (detect all but ONU)
