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.
- 파장: 1310/1550nm.
- 다이나믹 레인지: 26/24dB.
- Max Test Range: 최대 100km.
- 작업: 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.
- 보고: 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 광 파워 미터(OPM)
The OPM measures the optical power of a fiber optic signal.
