5. Impostazione

5.1. Accensione iniziale

1. Ensure the device is fully charged or connected to the power adapter.
2. Press and hold the power button (usually located at the bottom right of the control panel) until the screen illuminates.
3. Il dispositivo si avvierà e visualizzerà il menu principale.

5.2. Connecting Optical Fibers

Before connecting any fiber, ensure the connector end-face is clean. Use the provided cleaning swabs for optimal performance and to prevent damage.

1. Identify the correct optical port for your test (OTDR, VFL, OPM).
2. Select the appropriate adapter (SC, FC, ST, LC) for your fiber connector type.
3. Gently insert the cleaned fiber connector into the device's port until it clicks into place.

6. Modalità operative

The SS322T-2A3 integrates multiple testing functions. Navigate through the main menu using the touch screen or physical buttons to select the desired mode.

6.1. OTDR (Optical Time Domain Reflectometer)

The OTDR function is used to characterize optical fibers, locate faults, and measure loss. The SS322T-2A3 supports 1310nm and 1550nm wavelengths with dynamic ranges of 40dB and 38dB respectively, allowing for testing distances up to 165km.

Figure 6.2: A side-by-side comparison of OTDR test curves for 1310nm and 1550nm wavelengths, demonstrating different measurement parameters and results.

Performing an OTDR Test:

1. Dal menu principale, selezionare "OTDR".
2. Configure test parameters such as wavelength (1310nm or 1550nm), pulse width, range, and test mode (Auto or Manual).
3. Collegare la fibra da testare alla porta OTDR.
4. Press the "Start" button to initiate the test.
5. The device will display the OTDR trace and an event table.

Nota: The smaller the pulse width, the smaller the event dead zone (0.8m typical) and attenuation dead zone (4.5m typical), allowing for detection of close-range faults. However, a smaller pulse width also results in a smaller dynamic range.

6.2. OPM (Optical Power Meter)

The OPM measures the optical power of a fiber optic signal. The SS322T-2A3 supports wavelengths from 850nm to 1650nm and a power range of -60 to +3dBm.

Using the OPM:

1. Dal menu principale, selezionare "OPM".
2. Connect the fiber to the OPM port.
3. Il dispositivo visualizzerà la potenza ottica misurata in dBm.

6.3. OLS (Optical Light Source)

The OLS provides a stable optical signal for loss measurements when paired with an OPM. The SS322T-2A3 offers 1310nm and 1550nm wavelengths.

Using the OLS:

1. Dal menu principale, selezionare "OLS".
2. Select the desired wavelength (1310nm or 1550nm).
3. Connect the fiber to the OLS port. The device will emit a continuous wave or modulated signal.

6.4. VFL (localizzatore visivo di guasti)

The VFL emits a visible red laser (650nm, 2km range) into the fiber, allowing for visual identification of breaks, bends, or faulty connectors over short distances.

Utilizzando il VFL:

1. Dal menu principale, selezionare "VFL".
2. Collegare la fibra alla porta VFL.
3. Activate the VFL. Observe the fiber for any visible red light leakage, indicating a fault.

7. Event Map and Graphics Analysis

The SS322T-2A3 simplifies fiber analysis with its intelligent event mapping and graphics analysis modes, making it easier to identify and locate network components and faults.

Figure 7.2: A visual representation of the event map and graphics analysis mode, which simplifies the interpretation of OTDR traces by presenting events in an easy-to-understand graphical format.

After an OTDR test, the device can automatically generate an event map, visually representing splices, connectors, and other events along the fiber. The graphics analysis mode provides detailed information about each event, including distance, loss, and reflectance, aiding in quick fault diagnosis.

8. Smart APP Module and Data Management

The SS322T-2A3 supports connectivity with smart devices (Android/iOS/Windows) and PCs via a dedicated APP module. This allows for viewing, sharing, analyzing, and saving test data remotely.

Connessione alla Smart APP:

1. Download and install the SKYSHL Smart APP on your compatible device.
2. On the SS322T-2A3, navigate to "General Settings" -> "Network Settings".
3. Enable Wi-Fi or Bluetooth and connect to your smart device.
4. Follow the APP instructions to establish a connection and manage your test data.

Nota: The Smart APP functionality is currently optimized for Android devices.

9. Manutenzione

Proper maintenance ensures the longevity and accuracy of your SS322T-2A3 OTDR.

9.1. Pulizia

• Optical Ports: Always clean optical connector end-faces before each use with specialized fiber optic cleaning tools (e.g., cleaning swabs, lint-free wipes with isopropyl alcohol). Contamination is the leading cause of inaccurate measurements and damage.
• Screen and Casing: Use a soft, dry, lint-free cloth to clean the screen and device casing. Non utilizzare detergenti abrasivi o solventi.

9.2. Conservazione

• Quando non lo si utilizza, riporre il dispositivo nella sua custodia per proteggerlo dalla polvere e da eventuali danni fisici.
• Conservare in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
• If storing for extended periods, ensure the battery is partially charged (around 50%) and recharge it every few months to prevent deep discharge.
