Maintaining high network Service Level Agreements (SLAs) for broadband subscriber connections requires real-time insight into optical power attenuation, multi-hop network latency, and physical fiber stability. This technical guide outlines the architecture and implementation of an automated monitoring system designed for the Huawei HG8010H GPON ONT and TP-Link Archer C6 v5 AC1200 Router.
1. System Architecture & Network Topology
The monitoring system operates on a three-tier multi-hop diagnostic architecture that constantly audits packet delivery and optical power levels across all local and ISP network hops:
- Hop 1 (Local Wireless/LAN): Subscriber PC ➔ TP-Link Archer C6 v5 Gateway (
192.168.0.1) - Hop 2 (Ethernet Bridge): TP-Link Router ➔ Huawei HG8010H GPON ONT (
192.168.100.1) - Hop 3 (Upstream Core): Huawei ONT ➔ Fiber OLT ➔ Public Internet Core (
8.8.8.8)
2. Real-Time Telemetry & Telnet Optical CLI Polling
The backend telemetry engine connects directly to the Huawei ONT management CLI over internal Telnet (Port 23) using a low-overhead background polling loop. It parses live hardware parameters including optical power and CPU/RAM load:
# Huawei ONT Telnet Inspection Commands
WAP> display optic
WAP> display sysinfo
WAP> display deviceinfo
Key optical power parameters extracted in real time include:
- Rx Optical Power (dBm): Received light signal level from OLT. Normal range:
-8.0 dBm to -27.0 dBm. - Tx Optical Power (dBm): Transmitted laser power from ONT. Normal range:
+0.5 dBm to +5.0 dBm. - Transceiver Temperature (°C): Internal optic module operating temperature.
3. Real-Time Fiber Loss of Signal (LOS) Detection
When an optical patch cord is physically unplugged or cut, the system immediately captures RxPower: -- (dBm) or LinkStatus: failed from the hardware CLI, triggering an instant visual alert: FIBER UNPLUGGED (LOS).
4. Hardware Resource & SLA Audit Reporting
All metrics are persisted to an embedded SQLite database (uno_monitor.db) and rendered on a real-time web dashboard (Flask + Chart.js). The system features one-click generation of formal PDF Audit Reports (/audit-report) and CSV exports, complete with executive summaries, SLA threshold reference matrices, and historical fault timelines.
