IMPORTANT SAFETY INSTRUCTIONS
Before use, read the following safety instructions.
CAUTION：CAUTION to avoid hazards which may cause human injury or
may damage the instrument.
1. Warning for laser light
(1). These laser light product outputs “Laser Class1” light, which does not
damage human eyes.
However, if you gaze at the laser light intentionally, even a “Laser
Class1” laser may injure your eyes.
(2). Do not look into the ferrule face of the output port, or this can be
damaging your eyes.
(3). Do not point the output port at a person.
2. Cautions for a proper use
(1). Static electricity may damage the unit. Before use, discharge the static
electricity of the body by touching the metal of the building or other
object.
(2). Excessive ambient noise may affect the unit's normal operation.
If the unit is not working properly, turn it off and start operations again
from the beginning.
(3). The light emitting section of the output port must be kept clean and
free of dust and dirt at all times. Take particular caution when
removing and fitting the connectors and adapters. Be sure to use the
protection cap or case when the unit is not in use
For information regarding cleaning the output port, refer to “4.
Cleaning the output port”.
(4). Do not drop or swing the unit by the strap.
(5). Remove the battery when you will not use the unit for a long time.

1. Special features
(1). A light-weight pocket MINI Light Source designed to measure optical
power as well as fiber identification in fiber optics communication.
(2). The unit is equipped with a LED light source with wavelengths of
either 850nm or 1310nm and a LD light source with wavelengths of
either 1310nm or 1550nm.
(3). A unit that can be connected to various attachments through use of
the appropriate connector adapter.
(4). Auto power off function. (10 minutes)
(5). Small and attractively designed covering case that protects the
output port and operation buttons, suitable to be carried in one’s
pocket or a tool box.
2. Configuration
The Light Source consists of the main body and connector adapters
accommodating various fiber connectors;

①ON/OFF Button
This button activates the operation of the unit. Turn the unit off by
pushing the button while the unit is in operation.
To override the auto-off continue to press the ON/OFF button for
approximately 3 seconds when activating the unit, until the Power
LED (④-1) begins to blink.
②MOD Button
Each time the button is pressed, the modulation frequency of CW
(continuous wave) and CHOP wave changes as follows.
→CW →270Hz →1kHz →2kHz →
The selected modulation frequency is saved, and it is used when the
unit is turned ON next time.
In order to cancel “MOD” selection, and return the unit to its initial
settings, hold down both the ON/OFF button and the MOD button for
approximately 2 seconds when activating the unit.
The initial setting is CW (continuous wave).

③Output port
This port is where the laser power enters the fiber optics.
The interchangeable adapters are to be attached here. This port
accommodates a wide variety of connector types.
The 180-** type connector adapter is designed for use with the LED
light source(Model 351, 352)
The 181-** type connector adapter is designed for use with the LD
light source(Model 362, 363, 372, 373)
④ LED Display
④-1 Power LED
This LED shows that light is being emitted.
A blinking light indicates low battery power.
④-2 MOD LED
The selected frequency is shown by MOD Display LED.
⑤ Battery Compartment
The battery is to be installed here.
⑥ Strap hole
The strap is to be put on here.
⑦ Case
The case is used to protect the output port, the operation buttons,
and the LED display when the unit is not in use. It is not necessary
to remove the connector adapter when covering the unit with this
case.

3-2 Operation of Unit
（1）Battery
Slide the battery cover off and insert one AA
battery in the direction of the polarity mark
as indicated in the battery compartment.
（2）Case
Slide the case off and insert the unit into the case from the opposite
direction.
(3) Power
Activate the unit by pressing the ON/OFF button.
(4) The MOD Selection
Press the MOD select button to set the modulation frequency.
(5) Connector adapter
Tightly attach the connector adapter to the output port.
Tighten the adapter's screw while pressing the sleeve in to move
the pin into the guide hole. (181-** connector adapter)

(6) Measurement
For measurement purposes, attach the optical fiber connector to
the connector adapter. To get an accurate measurement, be sure to
maintain the physical configuration of the fiber throughout the time
of measurement.
Tighten the connectors securely. The ferrule face should be kept in
a clean environment away from dust at all times.
The LD light source may be unstable because of the backreflection.
Please connect an APC ferrule to the Optical Power Meter side to
prevent it.
3-3 Battery replacement
The blinking of the Power LED indicates that the battery is low and
needs replacing.
〔Reference〕
Connect two reference cables to the Light Sourece and measure output
at that time. P1(dBm)
〔Measurement〕
Connect the measuring fiber between reference cables and measure
output at that time. P2(dBm)

4. Cleaning the output port
Because the path traveled by light, at the PC polished output port, is
extremely small, any dust on the ferrule face not only disrupts
connection with the fiber, but also leads to greater coupling loss and
reflection. Dust can also damage the ferrule.
The output ports are cleaned as follows.
【When the connector adapter is attached 】
a. Remove dust from the ferrule face with a 2.5 mm CLETOP stick
or comparable product.
【When the connector adapter is removed 】
a. Wipe the ferrule face with a swab dipped in ethanol or
isopropanol.
b. Wipe the ferrule face with a dry swab once again.
c. Blow on the ferrule face with clean air.
