Any vendor's OLT, one console
Huawei, ZTE and VSOL chassis managed side by side — authorize ONUs, push VLANs and PPPoE credentials, read optical power and heal stuck ONTs remotely, without keeping three vendor CLIs and three playbooks alive.
Behind every port
See what the chassis sees
The console reads your OLTs' optics continuously — so the map knows a splitter died before the phones do, and every ONU behind it is already flagged.
All 12 ONUs online
Light on every fiber, optical readings live. One ONU is running a weak signal at −26.8 dBm.
What it does
OLT/ONU Management, in specifics
Multi-vendor by design
Huawei MA5600/MA5800, ZTE C300/C320 and VSOL in the same console, with vendor quirks — CLI dialects, firmware variants — absorbed by the platform, not your NOC.
ONU authorization
Discover unauthorized ONUs on the PON, authorize with the right line and service profiles, and bind the subscriber — one flow, any vendor.
PPPoE provisioning
Push VLANs and PPPoE credentials to the ONT remotely, convert static/IPoE WANs to PPPoE, and auto-heal ONTs stuck mid-conversion.
Optical health
Rx/Tx power per ONU with loss-of-signal detection — see the fiber break before the subscriber calls, and see exactly who sits behind it.
Bulk operations
Batched config pushes across whole PON ports or OLTs — onboarding a street of ONUs is one job, not an evening of copy-paste.
Shared plant, split books
Multiple ISPs on the same OLT each see and bill only their own ONUs — infrastructure sharing without data sharing.
Under the hood
For the reader who wants the details
Vendor coverage
Huawei MA5600T / MA5800 · ZTE C300 / C320 · VSOL- Session-pooled Telnet/SSH transport keeps vendor CLIs warm and rate-limited — operations execute in seconds without hammering the chassis.
- ZTE firmware dialect differences (old vs. new keyword sets) are detected and handled automatically.
- Read parity across vendors: running config, WiFi, VLANs, TR-069 status — the same buttons work on every chassis.
ONU lifecycle
Discovery → authorize → provision → monitor → heal- Unauthorized ONUs surface with serial, slot and port the moment they appear on the PON — authorization is a click, not a CLI session.
- Stuck ONTs that reboots don't cure are healed with a targeted deactivate/activate cycle from the console.
- Every ONU keeps its subscriber binding, so device state and billing state read as one record.
How it's priced
Which plan includes it
OLT/ONU management is part of Premium, priced per user like the rest of the platform. The number of OLTs and ONUs you manage doesn't change the bill, and mixing vendors costs nothing extra.
