OTDR is an optoelectronic integrated instrument made
of Rayleigh scattering and Fresnel reflection when
optical signal is transmitted in optical fiber. It is widely
used in the maintenance, construction and monitoring
of optical cable lines. It can measure the length of
optical fiber, transmission attenuation of optical fiber,
attenuation of connector and fault location.
Auto OTDR:
it only needs to set the wavelength and
measurement time, and other parameters are automat-
ically selected by the instrument to complete the test.
For the specific meaning and explanation of each
parameter, please refer to "expert OTDR".
Expert OTDR：
parameters such as wavelength, test
range and pulse width shall be set.
The test results are more accurate by selecting the
appropriate measurement parameters in the expert
mode. You can zoom in on the curve to see the details of
each event.
Wave:
the emit wavelength, which can be measured at
1310nm or 1550nm.
Test range:
range setting is based on the actual length
of the optical fiber to select the corresponding
predefined range, must be greater than the length of the
measured optical fiber, usually required to be set to
about twice the length of the measured optical fiber.
Auto test:
OTDR automatically matches the most
suitable parameters for the current test, and the select-
ed values of test range and pulse width cannot be
modified.
Manual mode:
set the value of measurement range and
pulse width manually.
Pulse width:
refers to the time width of the optical
pulse signal emitted during test. The larger the pulse
width, the stronger the optical power injected into the
optical fiber, the stronger the backscattering signal of
the optical fiber is, and the farther the effective detec-
tion distance of the OTDR can be. However, the large
pulse width will cause saturation of the initial reflection
signal and a large blind area. The choice of pulse width
is related to the length of the optical fiber. The longer
the length, the larger the pulse width, which can only be
modified in real-time/average measurement mode.
Threshold settings
Event loss threshold:
set the loss threshold of connec-
tion point, fusion point or macro bend in the link that
can be tested, between 0.2~30dB, and the default value
is 0.2dB. Events larger than the set threshold will be
listed in the event table, or those will be ignored.
Reflection threshold:
set the return loss threshold of
the link reflection events that can be tested, ranging
from 10dB to 60dB, and 40dB by default.
End threshold:
set end loss at the end of the link that
can be tested, ranging from 1~30dB, 10dB by default.
Eligibility criteria
Set the judgment value for the average loss of connec-
tion/fusion/bending/link. If it is less than the value, it is
judged as "PASS", otherwise it is "FAIL".
Connection loss:
reflection event, refers to flange, SC,
LC and other joints;
Welding loss:
non reflective event, refers to fusion;
Bending loss:
non reflective events caused by fiber
bending, need to be tested at two wavelengths at once;
Average loss:
the loss value per kilometer of the link
under test.
Select correct parameter, the test results such as curve
and event list will be displayed after test completed.
IOR:
provided by optical cable or fiber manufacturer.It is
the key parameter for calculating the distance, and can
not be set arbitrarily.
Test time:
it is used in the average test mode. The longer
the test time is, the better the signal-to-noise ratio of the
signal is improved, and the more accurate the test result is.
The user should choose the test time reasonably. It is
proportional to the dynamic.
Unit: select the required unit, there are three options for
km/kfeet/miles.

PREFACE
This series of OTDR is a multi-functional optical measuring instrument, which integrates auto OTDR,
expert OTDR, event map, optical power meter, visual fault location, power adjustable stable light
source, end face detection, optical loss test, cable line length / sequence test, cable tracking and
other functions. It has touch screen and heys. It is the right assistant for optical cable construction,
installa-tion and maintenance, project acceptance and on-site repair.
When using the instrument, do not look directly at the laser output port or the end of the optical fiber
with your eyes, avoid eye damage! Except for 1625nm/1650nm, all the others are off-line test wave-
lengths, which will cause damage to internal components of the instrument if forced to use! Any
change or modification not explicitly permitted in this manual will deprive you of the right to operate
the equipment. To reduce the risk of fire or electric shock, do not expose the equipment to thunder-
storm or humid environment. In order to prevent electric shock, please do not open the shell. It must
be repaired by qualified personnel designated by the manufacturer
Battery:
the battery is a special polymer lithium battery, the charging voltage is 5V/2A, and the
charging temperature range is 0 ℃~ 50 ℃. When the ambient temperature is too high, the charging
will automatically terminate. The battery should be charged every one month to avoid long storage
time and failure of battery due to self discharge. The temperature range of battery during long-term
storage is: - 40 ℃ ~ 50 ℃.
Please use the special adapter attached with the instrument box and use the external power supply
in strict accordance with the specifications, otherwise the equipment may be damaged.
End Face Cleaning:
Before testing, clean the end face of the tested fiber joint with alcohol cotton.
LCD screen:
the display of this series of instruments is 4.3 inch color LCD. In order to maintain good
viewing effect, please keep the LCD screen clean. When cleaning, wipe the LCD screen with soft fabric.
