PathTrak Return Path Monitoring System

Trusted Return Path Monitoring & Troubleshooting Solution

PathTrak provides superior spectrum and QAM analysis capabilities enabling the most efficient and effective monitoring and troubleshooting capabilities. Now fully supported by XPERTrak software, PathTrak is an integral part of the VIAVI Solutions overall HFC maintenance, monitoring, and troubleshooting portfolio.

PathTrak™ is the most advanced and extensively deployed return path monitoring system today, fully integrated with VIAVI field instruments. With over 750,000 nodes monitored globally, PathTrak is the industry-standard tool for detecting and resolving return path issues. 

Live spectrum and QAM analyzers leveraging PathTrak hardware are invaluable for technicians to efficiently resolve issues in the field. Pervasive fast impulse noise must be reliably detected, only PathTrak can adequately address this common use case. Technicians can’t wait 30 seconds or more for feedback from existing polling-based solutions to see the impact on codeword error rates from tightening a connector or wiggling a drop cable, PathTrak’s QAMTrak Analyzers update multiple times per second providing nearly instant feedback.

Beyond just superior find and fix tools, PathTrak is constantly monitoring both spectral and packet health, alarming on critical issues, and trending the data to spot impending issues before customers are impacted.  With high port-density and low power consumption, the PathTrak HCU200 platform scales well down to small node sizes as operators drive fiber deeper into their plants.  When the time comes to begin transitioning to Remote PHY, a smooth migration path including continuity of critical HFC maintenance capabilities is ensured through the PathTrak/XPERTrak integration.
