Verifying Your OTDR

To measure the dynamic range:
1.
Connect the OTDR as indicated below. Other configurations are

possible, such as the one explained in the section on how to determine
measurement range, if you use the shortest fiber length from that
setup. In all cases, the fiber should have several sections longer than
2 km, with no loss greater than 8 dB and with an average attenuation
not exceeding 1 dB/km.

Ensure the OTDR port and connectors are correctly cleaned, and that
the fiber settings are accurate (IOR, Helix factor, and RBS).
