Avertissement
When using the instrument, do not look directly at the laser output port or the end of the optical fiber with your eyes, avoid\u00a0
eye damage!Dual wavelength testing of 1310nm&1550nm is prohibited online, as forced use may cause damage to internal\u00a0
components of the instrument!Any change or modification not explicitly permitted in this manual will deprive you of the right\u00a0
to operate the equipment. To reduce the risk of fire or electric shock, do not expose the equipment to thunderstorm or humid\u00a0
environment. In order to prevent electric shock, please do not open the shell. It must be repaired by qualified personnel\u00a0
designated by the manufacturer.
Attentions
Battery: The battery is a special polymer lithium battery, the charging voltage is 5V\/2A, and the charging temperature\u00a0
range is -5\u2103~+45\u2103. When the ambient temperature is too high, the charging will automatically terminate. The battery should\u00a0
be charged every one month to avoid long storage time and failure of battery due to self discharge. The temperature range of\u00a0
battery during long-term storage is: – 20 \u2103 ~ 50 \u2103.
Please use the special adapter attached with the instrument box and use the external power supply in strict accordance\u00a0
with the specifications, otherwise the equipment may be damaged.

OTDR-Set test parameters
Wave: The wavelength at which light waves are emitted.
Range: Select the corresponding predefined range based on the\u00a0
actual length of the optical fiber, which must be greater than the\u00a0
length of the measured optical fiber, usually set to about twice the\u00a0
longueur de la fibre optique mesur\u00e9e
Pulse : Refers to the time width of the optical pulse signal emitted\u00a0
during measurement. The larger the pulse width, the stronger the\u00a0
optical power injected into the fiber, the stronger the backscatter\u00a0
signal of the fiber, and the farther the OTDR can effectively detect.\u00a0
However, a large pulse width can cause saturation of the initial reflection signal, resulting in a large blind spot. The selection of pulse width is related to the length of the measuring fiber. The\u00a0
longer the length, the greater the pulse width, which can only be modified in real-time\/average measurement mode.
Mode: The equipment is divided into three modes: automatic testing, average testing, and real-time testing. Automatic testing auto
matically selects testing conditions without the need for manual selection. Average testing and real-time testing require manual\u00a0
selection of testing conditions.
Time: In the average measurement mode, the longer the detection time, the better the signal-to-noise ratio improvement of the\u00a0
signal, and the more accurate the test results. Users should choose the measurement time reasonably, and the measurement time is\u00a0
directly proportional to the measurement dynamics.
Unit: Select the desired unit, with three options available: km, kft, and mi (miles).
Auto save: Whether to automatically save the test file after testing is completed.
Refractive Index: Determined by the inherent characteristics of optical fibers and provided by cable or fiber manufacturers, refrac
tive index is a key parameter for calculating distance and cannot be set arbitrarily. The range of refractive index is 1-2.
Key operation: Press the SET key to enter parameter settings, select parameters up, down, left, right, and OK to confirm the parameters.
OTDR-Threshold\/Criterion
Threshold setting
Event loss threshold: Set the loss threshold for the connection\u00a0
points, fusion points, or macro bends in the link that can be tested,\u00a0
between 0.01dB and 9.99dB, with a default of 0.20dB. Events exceed
ing the set threshold will be listed in the event table, while events\u00a0
below the threshold will be ignored.
Reflection threshold: Set the return loss threshold for the link reflec
tion events that can be tested, between -99.99dB~1.00dB, with a\u00a0
default of -40.00dB.
End threshold: Set the loss value at the end of the link that can be\u00a0
tested, between 1dB and 30dB, with a default of 10dB.
Qualification criteria
Set a judgment value for the average loss of connection\/fusion\/bend
ing\/link. If it is less than the judgment value, it is judged as “PASS”,\u00a0
otherwise it is “FAIL”.
Connection loss: Reflection event, referring to flange, SC, LC and\u00a0
other joints;
Welding loss: Non reflective event, often referring to the welding\u00a0
point;
Bending loss: Non reflective event caused by fiber bending, requiring\u00a0
simultaneous testing of two wavelengths;
Link loss: The total loss threshold value of the tested link.
Average loss: The loss value per kilometer of the tested link.<\/p>\n\n\n\n

Instrument maintenance
Cleaning of connectors
\u00a0The optical output interface of this series OTDR is replaceable, and the end face must be kept clean during use. When\u00a0
the instrument fails to test a normal curve or the test results are inaccurate, the first consideration is to clean the connector.
When cleaning, please ensure that both OTDR and visible red light fault location functions are turned off. Unscrew the\u00a0
output interface and use a dedicated dust-free tissue or cotton swab dampened with alcohol to wipe the connection end\u00a0
face.
At the same time, please cover the dust cap after using the instrument and keep it dust-proof and clean.
Instrument screen cleaning
The display of this series of optical time domain reflectometer is a 4.3-inch TFT full view color LCD with a capacitive\u00a0
touch screen. When using, sharp objects should not be used to click on the LCD screen, as it may be damaged. When\u00a0
