3.1 OTDR Testing Modes

3.1.1 Auto OTDR Mode

This mode simplifies fiber testing, making it accessible even for untrained technicians. With a single touch, the device automatically:

• Performs link recognition.
• Sets optimal testing parameters.
• Launches multiple acquisitions and analyses across various wavelengths.
• Consolidates results for each link section and network element.

Results can be exported to a single report for easy analysis.

3.1.2 Expert OTDR Mode (Manual Testing)

For experienced users requiring precise control, the Expert OTDR mode allows manual parameter configuration. Follow these steps:

1. Select 'Expert OTDR' from the main interface.
2. Adjust parameters such as wavelength (1310nm, 1550nm), test range, pulse width, and test time as needed.
3. Initiate the test. The device will display the OTDR trace curve, providing detailed information about the fiber link.

3.2 Event Map / Graphical Analysis

The Event Map mode provides a simplified, graphical representation of the fiber optic network. It uses intelligent algorithms to dynamically locate and identify all network components and fault locations with maximum resolution. This visual aid helps engineers quickly understand the network topology and pinpoint issues.

3.3 Integrated Functions

The SS304T-2A1 combines several tools to streamline your work:

• Optical Power Meter (OPM): Measures optical power from 850nm to 1650nm with a range of -50 to +26dB. Select the OPM icon and connect the fiber to the OPM port.
• Visual Fault Locator (VFL): Emits a 650nm red laser light for visual fault location up to 10km. Useful for identifying breaks, bends, or faulty connectors. Select the VFL icon and connect the fiber to the VFL port.
• Optical Light Source (OLS): Provides stable light sources at 1310nm and 1550nm (≥-5dBm/CW, 270Hz, 330Hz, 1kHz, and 2kHz). Used for optical loss testing. Select the OLS icon and connect the fiber to the OLS port.
• Optical Loss Test (OFLT): Measures optical loss at 1310nm and 1550nm. Requires both OLS and OPM functions.
• RJ45 Cable Tracker: Used to track RJ45 cables over 300m. Connect the main unit to one end of the RJ45 cable and the remote module to the other end.

3.4 Data Storage and Management

The device can store up to 300,000 groups of curve data (8GB internal storage). Test results can be saved in SOR format. Use the 'File Management' option on the main interface to access, review, and manage stored data.

3.5 Language Settings

The device supports multiple languages. Navigate to the 'System' settings to change the interface language to English, Russian, Spanish, French, Portuguese, or German.

4. Maintenance

• Inaccurate OTDR Readings:
  • Clean all fiber end-faces and optical ports thoroughly.
  • Ensure correct adapter type is used and securely connected.
  • Verify test parameters (wavelength, pulse width) are appropriate for the fiber length and type.
  • Check for excessive bends or damage in the fiber under test.
• VFL Light Not Visible: Ensure the VFL function is activated and the fiber is properly connected. Check for severe breaks in the fiber that might block light.
• RJ45 Cable Tracker Not Working: Verify both the main unit and the remote module are correctly connected to the RJ45 cable ends. Ensure the function is selected on the device.
• Touch Screen Unresponsive: Restart the device. If the issue persists, contact support.

7. User Tips

• Cleanliness is Key: Always ensure fiber end-faces and optical ports are meticulously clean before any connection. Dust and debris are the leading causes of inaccurate readings and potential damage.
• Understand Your Network: Before testing, have a clear understanding of the fiber network's layout and expected components. This helps in interpreting OTDR traces and event maps more effectively.
• Auto vs. Expert Mode: For quick assessments or less experienced users, the Auto OTDR mode is highly efficient. For detailed analysis or specific fault finding, leverage the Expert OTDR mode to fine-tune parameters like pulse width and range.
• Utilize Event Map: The graphical Event Map simplifies complex trace data into an easy-to-understand visual representation of events and their locations. Use it for quick identification of issues.
• Regular Calibration: While the device comes calibrated, periodic checks against known good fibers can help ensure continued accuracy.
