Title: Lannes S Purnell: Innovator in Cable Crosstalk Measurement Systems

Introduction

Lannes S Purnell is a notable inventor based in Edmonds, WA (US). He has made significant contributions to the field of telecommunications, particularly in the area of cable diagnostics. His innovative work has led to the development of a unique patent that addresses critical issues in LAN cable performance.

Latest Patents

Lannes S Purnell holds a patent for a Cable Crosstalk Measurement System. This system provides fault diagnostic information to locate faults in LAN cables while also offering a crosstalk versus frequency function for testing and troubleshooting. The invention introduces a narrow pulse into one twisted pair of a standard LAN cable and monitors another twisted pair for crosstalk signal coupling. The measurement system digitizes crosstalk signals through sequential sampling of repetitive signals, creating a waveform record that represents a real-time crosstalk signal. A microprocessor performs a fast Fourier transform on this waveform record to provide crosstalk versus frequency information. Additionally, the system examines the waveform record for higher-than-acceptable amplitude levels to identify poor quality or faulty connectors and cables.
