Why is my Huawei Network Router ONT failing to register?
- KKim GonzalezAug 11, 2025
ONT registration failure on your Huawei Network Router can occur due to several reasons. The PON terminal might be going online in an incorrect mode. Alternatively, the optical fiber connected to the ONT could be of poor quality or loosely connected. The optical power of the ONT might not be within the normal range. Also, the minimum and maximum logical distances configured on the OLT port to which the ONT is connected might be inconsistent with the actual distances. The ONT auto-find function could be disabled on the OLT port. Furthermore, when the ONT is added, the configured SN of the ONT might differ from the actual ONT SN, or an ONT with the same SN might already be connected to the OLT. Finally, the ONT might be a rogue ONT.
