Add read-only SFP+ transceiver diagnostics to the Archer BE800 web interface
Feature Request:
The Archer BE800 includes a 10Gbps SFP+/RJ45 combo WAN/LAN port. For users who connect fiber modules, ONU devices, or other SFP+ equipment to this port, it would be very helpful if the router’s web interface could display basic, read-only transceiver diagnostics for supported modules.
Why this would be useful:
At the moment, the BE800 provides very limited visibility into the connected SFP+ device. In practice, this makes troubleshooting much harder when there are connection issues, unstable links, overheating modules, weak optical levels, or suspected hardware-related problems. A small diagnostics page would make it much easier to determine whether the issue is related to the module, the fiber path, the connected device, or the router itself.
Requested information:
For supported modules, please show read-only information such as:
- module presence / detection
- vendor / model / identification
- link status and negotiated speed
- temperature
- voltage
- bias current
- Tx power
- Rx power
These are the same kinds of values TP-Link already documents for DDM-supported SFP modules in its own business networking products.
Why this fits the BE800:
The Archer BE800 is positioned as a premium Wi-Fi 7 router with 10G connectivity, including a 10G SFP+/RJ45 combo port for both fiber and copper use. Because of that, basic SFP+ diagnostics would be a natural and practical addition for advanced home users and small-office users who want to monitor their fiber uplink properly.
Expected benefit:
This feature would reduce troubleshooting time, improve supportability, and make the SFP+ port far more useful for users who actually deploy fiber or SFP+ hardware on the BE800.
Important note:
This request is not asking for advanced management features, alarms, or automatic shutdown behavior. The initial goal is simply to expose existing transceiver diagnostics in the BE800 web UI in a clean and user-friendly way. If a module does not support DDM/DOM, the UI could simply show that diagnostics are unavailable for that module.
Thank you for the detailed introduction to this new feature. We have noted your feedback, and we also welcome other users to actively participate in the discussion and voting.
