Title: Sigfried Fleischer and His Optical Fiber Testing Invention.

Introduction

Sigfried Fleischer is an inventor based in Los Gatos, California. His patent work includes an optical testing cable designed to connect a pluggable optical time domain reflectometer (OTDR) to a fiber span under test.

Latest Patents

Fleischer is associated with 1 patent: “Circulator Cable for Use with a Pluggable Optical Time Domain Reflectometer.” The invention describes a cable with a bandpass optical filter and a directional optical coupling device. Together, these components direct an OTDR’s optical probe signal toward the fiber span and route reflections from the span into the filter.

Career Highlights

Fleischer is associated with II-VI Delaware, Inc. His patent focuses on optical fiber testing, helping an OTDR send probe signals into a fiber span and receive the resulting reflections through a pluggable connection.

Collaborations

Fleischer’s listed coworkers include Ian Peter McClean and Vincent Ouyang. Their names provide context for his professional connections, though the supplied information does not specify their roles in this patent.

Conclusion

Sigfried Fleischer’s patent describes a circulator cable that supports optical time domain reflectometry by managing probe signals and their reflections, contributing to the practical testing of optical fiber spans.
