Original PathTrak CPU‑5500 main control module, core processing unit for HFC return‑path spectrum monitoring chassis.

Product Overview

PathTrak CPU‑5500 is the central controller module for PathTrak return‑path monitoring system. It acts as system core processor, coordinates all receiver modules inside chassis, completes spectrum data collection, processing and alarm judgment, transmits monitoring data to upper‑level monitoring platform through Ethernet interface. It supports firmware online upgrade, widely used as maintenance spare part for cable broadband head‑end HFC network noise detection and signal monitoring.

Key Features

• Centralized control for PathTrak chassis, coordinates multiple receiver modules for unified monitoring tasks
• Real‑time spectrum data aggregation, threshold judgment and fault alarm output
• Ethernet network interface for connecting to upper monitoring server and NOC platform
• Backplane power supply, no external power adapter, simplifies cabinet wiring
• Supports firmware upgrade for function iteration and system maintenance
• Hot‑swappable field‑replaceable module, reduces system maintenance downtime

• No interference to RF signal path, independent control and data processing
