Module 03 — Optical-Fiber NMS

Your entire fiber plant, on one screen.

Live GPON and EPON monitoring built for ISPs — OLT and ONU health, signal strength, alarms, outage root cause and PON capacity in one console, speaking SNMP and TR-069 to your Huawei and ZTE OLTs.

NMS dashboard per-OLT service health beside the live ONU signal-strength distribution

01 — The control room

Every OLT, every ONU,
at a glance.

The dashboard puts service health and the live signal distribution side by side, so the state of the plant is obvious the moment you log in.

01 Live OLT/ONU monitoring Per-ONU signal strength, distance and status across GPON and EPON, graded into good, normal, bad and dead health bands with the average dBm alongside.

02 Per-OLT service health Web, Database, VPN, TR-069 and SNMP checked for every OLT in a single row — with notifications the moment any of them drops.

03 PON gauges Total, online and offline ONUs per EPON and GPON, plus power, LoS and health splits — the whole population in a few dials.

04 Configured & unconfigured ONUs Both populations tracked separately, so a unit waiting on provisioning never slips through.

05 PON capacity planning See which ports are filling up and where to expand next — before you run out of headroom.

02 — Faults & maps

Faults that explain themselves.

Stop guessing at 2am. Alarms land in one console, recurring outages get a named cause, and everything is plotted where it physically lives.

Alarm console

From symptom to cause, automatically

Faults across OLTs and PON ports escalate to a single console the moment they happen. When an area keeps going dark, recurring-outage detection names the underlying cause — an electricity issue on a feeder, not a vague alert.

Automatic fault detection — across every OLT and PON port, in one list
Named root cause — repeat outages diagnosed, e.g. an "electricity issue"
Service health watch — notifications for web, database, VPN and SNMP outages

Alarm console listing active network faults — **Alarm console** active faults across OLTs and PON ports, with recurring-outage root cause

Network map

See it where it lives

Faults and coverage make far more sense on a map than in a table. Your whole footprint — OLTs, towers and fiber routes — sits on one geographic view with live overlays.

Full plant plotted — OLTs, towers and fiber routes in their real positions
Fault overlays — affected segments highlighted, so crews dispatch to the right spot
Coverage overlays — served areas mapped for planning and sales conversations

Geographic network map with OLTs, towers and fiber routes — **Network map** OLTs, towers and fiber routes with live fault and coverage overlays

03 — Subscriber depth

Down to a single ONU

Drill into any subscriber's optical network unit and the whole story is on one page — what it is, where it hangs off the plant, and how its light looks right now.

Full ONU record — serial, board/port, splitter, signal, distance and authorization date
Health at a glance — live status and signal strength in the same view
Provisioning trail — configured and unconfigured units kept in separate lists

How provisioning works

ONU detail with serial, port, splitter, signal and distance — **ONU detail** serial, board/port, splitter, signal, distance and authorization date

TR-069 auto-configuration

Fix the CPE without a truck roll

Reach into subscriber CPE over TR-069 straight from the ONU page — read the full device picture, push the settings that close the ticket, and verify the line before you hang up.

Instant diagnostics — pull device info, system status and web login in one shot
Remote configuration — push WiFi, WAN and firewall settings, or queue tasks to run when the device checks in
Line verification — run ping, traceroute and speed-test from the CPE itself

TR-069 auto-configuration panel with device info, system status and web login — **TR-069 panel** device info, system status and web login read straight from the CPE

04 — Fiber intelligence

The math that finds the break.
Before the calls start.

Xelynx computes the dBm you should see at every hop — TX power minus splice and splitter loss, minus fiber at 0.35 dB/km — and compares it with the ONU's measured RX. The difference exposes bad splices, bends and failing splitters, and points to the break.

Animated PON topology tracing core to OLT to splitter to ONUs, comparing expected and measured dBm and localizing a fibre cut 1.24 km from the OLT — **Fiber intelligence, live** expected vs measured power down the PON — and the cut localized 1.24 km from the OLT

Fibre Connectivity tab

Expected vs measured power, hop by hop

Every ONU carries its full optical path. The Fibre Connectivity tab lays out the predicted and the real power at each splice and splitter, so an out-of-spec span jumps out instantly.

Per-hop comparison — expected against measured optical power down the entire path
Drops attributed — a power loss pinned to the exact section of fiber, not the whole run
AI critical alerts — persistent issues flagged, e.g. "signal variance 13.99 in 24h, bad fibre path"

Fibre Connectivity tab with expected versus measured optical power per hop and an AI critical alert — **Fibre Connectivity** expected vs measured power at every hop, with an AI critical alert

Fiber-cut localization

A cut, narrowed to the nearest box

Because the plant is modeled on the map, a dark span is a location, not a mystery. Xelynx walks the topology and localizes the fault down to the nearest distribution box — while the dashboard's Outages tab renders the OLT chassis live.

Map-modeled plant — a cut becomes a precise place to send the crew
Live chassis view — every port drawn as up, down, fibre-cut or power issue, like the physical card in front of you
Cross-checked — per-ONU power drops confirm the finding under Fibre Connectivity

Live OLT chassis in the Outages tab showing port up, down, fibre cut and power issue states — **Outages tab** the live OLT chassis — each port up, down, fibre-cut or power issue

05 — Reach

Every OLT, reachable anywhere.

Public IP or private address behind NAT — every OLT gets onto the platform, and its page shows exactly how it is being reached.

OLT live dashboard

The hardware, polled in real time

One page per OLT ties status, capacity and traffic together for fast triage — with the physical machine's health read live, not from the last sync.

Live hardware health — power supplies, fans, CPU and the full chassis
Clear reachability — a "Reachable via VPN tunnel" badge shows the active path
Everything on one page — status, capacity and traffic for the whole device

OLT live dashboard showing power, fan, CPU and chassis, reachable via VPN tunnel — **OLT live view** power, fans, CPU and chassis — reachable via VPN tunnel

Secure VPN tunnel

Behind NAT is not out of reach

OLTs on private addresses come onto the platform through a built-in encrypted tunnel — no port-forwarding, no exposure. The OLT page shows the live tunnel state next to the configuration that brings it up.

No port-forwarding — NATed OLTs reached through an encrypted tunnel
Live tunnel status — connection state shown right on the OLT page
RouterOS config inline — the tunnel setup presented next to its status, so bring-up is copy-and-go

OLT VPN tunnel status alongside RouterOS tunnel configuration — **Tunnel status** live VPN state beside the RouterOS configuration that creates it

06 — Graphs

From a microburst
to a full year.

Every PON port, every uplink and every subscriber gets its own graph — at five-second resolution for live debugging, out to a year for capacity decisions.

Per-PON-port and uplink traffic graphs for an OLT — **OLT graphs** each PON port and uplink interface on its own traffic graph — spot a saturated port early

Combined ONU traffic and signal-strength graphs over time — **ONU timeline** traffic and signal strength plotted together — a busy line and a degrading one look nothing alike

Graph	What it shows	Resolution
PON port traffic	Per-interface load for every PON port — not an aggregate	5 seconds to 1 year
Uplink traffic	Each uplink interface graphed on its own, for split and upgrade planning	5 seconds to 1 year
ONU traffic + signal	Throughput and optical dBm on one shared timeline per subscriber, so drops correlate with events	5 seconds to 1 year

07 — Day-to-day operations

The details that keep a NOC honest.

Streaming events, hands-on topology editing and a console you can lock in a tap.

Real-time SNMP notifications

SNMP traps stream into a side panel as they arrive — port flaps, fiber cuts and power issues land in front of you the instant the network reports them.

Optical-core editor

Double-click any map marker and choose "Edit Layout" to open an mxGraph editor of the splitter and optical-core layout — model the real plant, splice by splice.
