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). This 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.

〔State of initial settings〕
1. Special features
(1). A light-weight pocket MINI DUAL LIGHT SOURCE designed to measure optical
power in fiber optics communication.
(2). The wavelength of LD light source from a single output port can be switched.
Model 364 have 1310 nm LD and 1550 nm LD.
Model 368 have 1310 nm LD and 850 nm VCSEL.
(3). A unit can be connected to various attachments through use of the appropriate
connector adapter.
(4). Auto power off function. (In about ten minutes)
(5). Small and well-designed case protects the output port and operation buttons,
making it suitable for carrying in a pocket or tool box.
2. Configuration
The Light Source consists of the main body and connector adapters accommodating
various fiber connectors.
3. Operation instruction
3-1. Descriptions of parts

LD light source
To cancel the wavelength setting and modulation frequency,
and return the unit to its initial settings, hold down both the
power switch button and the MOD/λ＞1s. button for approximately 2 seconds
when activating the unit.
The initial settings are the 1310 nm and CW (continuous wave).
③Output port
This port is where the optical power enters the fiber optics.
The interchangeable adapters are to be attached here. This port accommodates
a variety of connector types.
④LED Display
④-1 Power Display and λDisplay ( and λ)
〔Power Display ( )〕Shows that light is being emitted.
〔Low Battery〕A blinking light indicates low battery power.
〔λ Display (λ)〕MODEL364 Red indicates that 1310nm LD is emitting.
Green indicates that 1550nm LD is emitting.
MODEL368 Red indicates that 1310nm LD is emitting.
Green indicates that 850nm VCSEL is emitting.
④-2 MOD Display (MOD)
The selected frequency is shown by MOD Display LED.
⑤. Battery Compartment
The battery is installed here.
⑥. Strap hole
The strap is attached here.
⑦. Case
The case protects the output port, operation buttons, and the LED display area
when the unit is not in use.
3-2. Operation of Unit
(1). Battery insertion / replacement
Slide the battery cover off as indicated. Insert or
replace one AA battery as indicated by the polarity
marks in the battery compartment.
(2). Case
Slide the case off, turn it over, and insert the unit from the opposite direction.

(3). Turn on the power
Activate the unit by pressing the button. The wavelength and the
modulation frequency maintain the state when the power is turned off.
(4). Change of the wavelength (MOD/λ＞1s.)
Continue to press the λ＞1s. button to change the wavelength for approximately
1 second. The Power Display LED emit light to red or green.
〔MODEL364 1310nm:Red, 1550nm:Green〕
〔MODEL368 1310nm:Red, 850nm:Green〕
(5). Select the modulation frequency (MOD/λ＞1s.)
Press the MOD button to set the modulation
frequency.
(6). Connect the connector adapter
Tightly attach the connector adapter to the
output port.
(7). Connect the optical fiber
Attach the optical fiber connector to the
connector adapter.
Tighten the connectors securely.
The ferrule face should be kept in a clean
environment away from dust at all times.
3-3. Battery replacement
The blinking of the Power Display LED indicates that the battery is low and needs
replacing.
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.
