OTDR Selection Guide

1. What type of optical fiber do you primarily need to test? *

2. Which specific test wavelengths do you require? *

3. Which of the following is your primary application scenario? *

4. What is the maximum length of a “single fiber link” you need to measure? *

This directly determines the core metric of the OTDR—the Dynamic Range (dB).

5. Are there any optical splitters in your test link? *

Splitters introduce massive optical attenuation; standard OTDRs cannot penetrate high-ratio splitters.

6. Do you need to perform “Live / In-Service Testing”? *

Testing while the fiber is active with traffic, without interrupting communication.

7. What type of optical fiber connectors do you encounter most frequently? *

8. Would you like the device to integrate any of the following built-in tools?

9. What style of equipment form factor and operation do you prefer? *
