It is very simple to use, just need to perform the following four steps:
1) Insert temperature sensing optical cable
The connector of the temperature sensing optical cable must be correctly inserted into the device. The type of temperature sensing fiber optic cable connector is FC/APC. When inserting the optical cable plug, please make sure to align the protrusion on the plug with the groove in the socket, and then tighten the thread, as shown in the following figure:
When removing the connector from the adapter, please cover it with a protective cap to prevent dust from entering and affecting system performance.
2) Power on the device
Before powering on, connect the keyboard, mouse, and VGA display.
Power requirements: AC 220V, 50Hz
Connect the power cord to a power outlet
After connecting to the power supply, the system automatically starts up and runs the program.
3) Waiting for system self-test to complete
After the device is powered on, the software automatically loads and runs. After the software runs, it automatically starts detection. During the detection process, the status bar displays: System self-test… After the self-test is completed, it displays: Normal collection
4) View fiber optic cable temperature and spectrum
Switch to the temperature curve graph and view the real-time temperature of the optical cable.
Switch to the spectral curve graph and view the spectral signal of the optical cable.

3.7 Fiber optic parameters
Click on the menu: Settings | Fiber Optic Parameters, and the “Fiber Optic Parameters” dialog box will pop up,
Independently configure the fiber parameters for each channel.
Due to the different properties such as joint loss, loss coefficient, fusion point loss, and number of fusion points for each fiber optic cable, it is necessary to separately correct the fiber optic parameters for each channel after construction.
The left list displays channel names. Before setting a channel, select the corresponding channel number.
Starting position: The optical cable corresponds to the position of the optical cable in the software. As there is a reference fiber in the equipment, the starting position of the optical cable should be greater than the length of the reference fiber in the equipment. It is set up at the factory and does not require any modification.
Fiber length: reserved.
Demodulation coefficient: Temperature value T=a * x * x+b * x+c
a: Quadratic coefficient
b: Coefficient of first-order term
c: Constant coefficient
Import coefficient: The coefficient can be manually entered or directly imported from a file. Click “Import Coefficient” and the “Import Fiber Coefficient” dialog box will pop up:
Select a row corresponding to the fiber optic name and click the OK button.
Regional attributes: Fiber optic can be divided into multiple regions, and the attributes of each region can be configured separately. Regional attributes include: starting point of the region, temperature deviation, and transmission attenuation coefficient;
Add Area: Click the “Add” button to pop up the “Area” parameter dialog box,
Starting point position: the starting point position of the region;
Temperature deviation coefficient: The temperature deviation value in this area, the temperature measurement value plus the deviation coefficient;
Transmission attenuation coefficient: The optical fiber transmission attenuation coefficient in this area.
Delete Area: Select the row of the area to be deleted and click the delete button.
Modify Area: Double click the row of the area you want to modify with the mouse, and the “Area Parameters” dialog box will pop up.
If the optical fiber has multiple fusion points, the loss of each fusion point will cause the temperature curve to not be straight. ಆದ್ದರಿಂದ, different parameters, temperature deviation, and transmission attenuation coefficient need to be set for the area between each fusion point, as shown in the following figure:
The temperature curve corresponding to the above figure can be set in three regions, as shown in the table below:
Transmission loss coefficient of temperature deviation at the starting point of the region
1 300 0 0.000008
2 1000 2 0.0000085
3 2000 2 0.0000095
Transmission loss coefficient: affects the slope of the temperature curve, and adjusting the transmission loss coefficient of the channel can correct the slope of the temperature curve.
Example 1: Transmission loss coefficient=0.00000920
In Example 1, the set transmission loss coefficient is exactly the actual transmission loss coefficient of the optical fiber, and the blue temperature curve is relatively flat.
Example 2: Transmission loss coefficient=0.0001220
In Example 2, the set transmission loss coefficient is greater than the actual transmission loss coefficient, and the blue temperature curve slopes upwards.
Example 3: Transmission loss coefficient=0.00000620
In Example 3, the set transmission loss coefficient is smaller than the actual transmission loss coefficient, and the blue temperature curve slopes downwards.

Temperature display starting point: Since there is a portion of optical fiber inside the device, if only the temperature of the temperature measuring optical cable needs to be displayed, this value can be set to shield the temperature of the optical fiber inside the device. The default value is the internal fiber length of the device.
