The function is fully one key automatic test, and the
information such as the length of the optical fiber link to
be measured, the type of the joint and the position of
the breakpoint are displayed graphically, and the
results are clear and easy to understand.

It is used for signal power test and insertion loss test of
various equipment and photoelectric components. It
can identify and measure the power of 270/
330/1k/2kHz frequency laser.
Wavelength: switch the test wavelength.
Reference: set the current power as the reference
power.
Calibration: enter the calibration mode.
Threshold: set the threshold value of power measure-
ment. If it exceeds the threshold value, it will be marked
in red; if it is lower than the threshold value, it will be
marked green.
The conversion relations of absolute power, relative
power and linear power are as follows:

The visible light (red light) is injected into the optical
fiber, and the position of optical fiber fault point can be
easily and accurately determined by observing the light
leakage position on the tested fiber. It is suitable for the
detection of bare optical fiber, optical fiber jumper and
other optical fiber which can leak red light, and the near
end fault point and high loss section caused by micro
bending.
Open: turn on the red light and output in continu-
ous mode
1Hz: red light flashes at 1Hz
2Hz: red light flashes at 2Hz frequency
Close: turn off red light
It can output laser with the same wavelength as OTDR
function, which can be used to test the parameters of
telecommunication, CATV and LAN optical cables, test
the insertion loss, isolation and return loss of optical
passive components, and test the wavelength respon-
sivity of detector.
There are five working modes : CW, 270Hz, 330Hz, 1kHz
and 2kHz.
Open: turns on the laser source
Wavelength: switch the wavelength of laser source
Mode: switch laser source frequence, CW, 270Hz,
330Hz, 1kHz and 2kHz
Power +: increase the output power
Power - : reduce the output power
Prompt the power adjustment progress bar at the bottom:
sliding left and right can reduce and increase the output
power of the light source respectively.
It is used to test the insertion loss of optical passive
devices.
The OLT steps are as follows:
1) Connect LS and OPM optical port with standard
jumper, press 【 Open】 , after power is stable, press 【
Reference】 ;
2) The standard jumper is used to connect the test piece
to the optical port of LS and OPM, press 【Open】 ,
'Rel.Pow' is the insertion loss of the DUT .
Cable sequence： When testing, please connect to the
remote module at the bottom of the instrument.
There are two kinds of wires for RJ45 connector: straight
line and interleaved line.
Direct connection test: during the test, the indicator
lights of the host and remote device flash from 1 to 8
one by one.
Interleaved wire connection test: during the test, the
indicators at the remote test end will flash one by one in
the order of 3, 6, 1, 4, 5, 2, 7, 8.
Cable length test: test the length of network cable.
Calibration: input the overall calibration factor of
network cable length.
Display length = last result × calibration factor.
Network cable standard: T568A/T568B, the color
order of network cable is different according to different
standards.
Attention
The port is designated as the port on the right side
of the OTDR displayed in yellow color.
Please connect correctly or it may cause damage
to the equipment!
Warning
Please cut off the electricity before test！
After the cable tracking function is started, touch the
cable under test with the tracker, and when hear the
sound of continuous "drip drop", the target cable is
found.
The equipment is pressure resistant, and can be directly
tested online. Weak current equipment with DC voltage
less than 60V such as ethernet switch and router.
Test: turn on RJ45 cable tracking function.
The line finding mode of this machine is digital radar
type, which has strong anti-jamming ability. According
to the target distance and proximity, the frequency of
prompt tone is different.
Attention
The cable tracking port is designated as the port
on the left side of the OTDR displayed in yellow.
Please connect correctly or it may cause damage
to the equipment!
Set the system automatic shutdown, backlight
brightness, time and other information.
Automatic shutdown:
5/15/30/45/60 minutes/never
Backlight brightness: 20%/40%/60%/80%/100%
Sound: turn on or off touch and key tone
Language: displays the native language type
USB connection: connect to the computer after
opening and transfer data
Time & date: set the time and date
Restore factory settings: restore default values
Upgrade: native software update
System information: check the local information and
alarm record.

Auto OTDR： test range is
set manually, OTDR will
automatically select the
most suitable reference
pulse width. Expert OTDR
(real-time / average test):
test range and pulse width
can be adjusted manually.
The list on the right is for
reference only:
The description in the table on
the right is for reference only.
Please refer to the new instruc-
tion for detailed usage. In the
process
of
using
instrument, if you have any
questions, you can contact the
instrument supplier.
Cleaning of connectors
The optical output interface of this series of OTDR is a replaceable universal interface, and the end face
must be kept clean during use. When the instrument fails to test the normal curve or the test result is not
accurate, first consider cleaning the connector.
When cleaning, be sure to turn off OTDR and visible red light fault location function. Screw off the output
port and wipe the connection end face with a special dust-free paper towel or cotton swab wetted with
alcohol.
At the same time, please cover the dust cap after using the instrument, and keep the dust-proof clean at
the same time.
Instrument screen cleaning
The display of this series of optical time domain reflectors is 4.3 inch TFT full view color LCD with capaci-
tive touch screen. When using, do not click on the LCD with sharp objects, or the derivative LCD screen may
be damaged. When cleaning, clean the LCD screen with soft paper. Do not wipe the LCD screen with organic
solvent, otherwise it may damage the LCD screen.
