6.1 OTDR Test

The OTDR function is used to characterize optical fibers. It measures fiber length, loss, attenuation parameters, and generates an event map to locate link points and fusion points.

The MOT-51C OTDR's 5.55-inch OLED touch screen displaying an OTDR test curve with event list and parameters, indicating 1310/1550nm wavelengths and 24/26dB dynamic range.

• Wavelengths: 1310/1550nm.
• Dynamic Range: 26/24dB.
• Max Test Range: Up to 100 km.
• Operation: Select "OTDR" from the main menu. Configure test parameters such as range, pulse width, and average time. Initiate the test. The device will automatically analyze linkers and fusion points.
• Curve Analysis: The touch screen allows zooming and moving of test curves to display details.
• Reporting: Test reports can be generated, including waveform graphs, parameter settings, fiber event information, and fiber connection information. Reports can be saved in EXCEL, PDF, or screenshot formats.
• Note: This 1310nm/1550nm model cannot test live fiber.

6.2 Optical Power Meter (OPM)

The OPM measures the optical power of a fiber optic signal.

• Calibrated Wavelengths: 850/1300/1310/1490/1550/1625nm.
• Operation: Select "OPM" from the main menu. Connect the fiber to the OPM port. The device will display the measured optical power.

6.3 Visual Fault Locator (VFL)

The VFL emits a visible red laser to locate breaks, bends, and poor connections in fiber optic cables over short distances.

• Wavelength: 650 nm.
• Max Test Range: Up to 8 km.
• Operation: Select "VFL" from the main menu. Connect the fiber to the VFL port. Activate the laser. Observe the fiber for red light leakage at fault points.
• Safety Warning: Avoid direct eye exposure to the VFL laser.

6.4 Light Source (LS)

The LS provides a stable optical signal for various testing purposes, often used in conjunction with an OPM for loss measurements.

• Modes: CW (Continuous Wave), 270 Hz, 330 Hz, 1 kHz, 2 kHz.
• Operation: Select "Light Source" from the main menu. Choose the desired wavelength and modulation mode. Connect the fiber to the OTDR/LS port.

6.5 Optical Loss Test (OLT)

The OLT function is used to measure the insertion loss of optical passive devices or fiber links.

• Operation: Select "Optical Loss Test" from the main menu. This typically involves using the Light Source and OPM functions together to measure loss.

6.6 Multi-Functional Cable Testing

The device includes capabilities for testing copper cables.

• RJ45 Cable TDR Testing: Detects near-end, mid-end, and far-end faults in RJ45 cables. Maximum test length is 600 meters.
• Cable Length Measurement: Measures cable length for BNC, Cat 5/6, and elevator cables up to 1.5 kilometers.
• Operation: Select "Cable Tester" or "Cable Length" from the main menu. Follow on-screen prompts to connect the cable and perform the test.
