ONUs Overview
Overview
The ONU List shows every customer ONU across all your OLTs in one place — their status, signal levels, and which subscriber they belong to. It's where you search for a specific customer's box or hunt down every ONU running weak.
Required Permissions
- ONU → List; Assign / Unassign and per-ONU View have their own permissions.

| OLT Name | The parent OLT (links to its page). |
| Description | A label on the ONU (often the customer's name). |
| Subscriber | The linked account (or - if unassigned). |

| TX Power | Light the ONU transmits back (dBm). |
| OLT RX Power | Light the OLT receives from this ONU (dBm). |
| Last Seen / Last Poll | When the ONU was last online / last read. |

Filters
The Filter button reveals: OLTs (and then its PONs), Status (Online / Offline / Low Signal), Assignment (Assigned / Unassigned), and RX power bands (≥ −25 healthy, −25 to −27 marginal, below −27 weak). A Reset button clears them.
Bulk assign
Tick one or more ONUs and choose Action → Assign to link them to a subscriber in one go — see ONU Assignment. To link many ONUs to many different subscribers automatically, use the dedicated assignment screen.
Understanding the readings
Everything here comes from the last poll of the parent OLT — nothing is measured live on this page (the Last Poll column tells you how recent it is). RX Power is the most important number: the more negative the dBm, the weaker the light. An online ONU below the low-signal threshold is flagged Low Signal — connected, but at risk.
