RF MEASUREMENTS OF FIBER OPTIC COMPONENTS Roger'Vong Network Measurements Division 1400 Fountain Grove Parkway Santa Rosa, CA 95401 RF & Microwave Measurement Symposium and Exhibition rli~ HEWLETT ~~ PACKARD www.HPARCHIVE.com RF MEASUREMENTS OF FIBER OPTIC COMPONENTS ABSTRACT RF network analysis is a useful technique for measuring the baseband electrical characteristics of fiber optic components. This paper is intended as a measurements tutorial and presents a brief description of the measurement theory and measurement block diagrams, including discussion of instrumentation requirements for attenuation and bandwidth measurements of optical fiber. In addition, fault location and modal dispersion measurements achieved through conversion of frequency domain information via the inverse Fourier transform to the time domain are described. Author: Roger Wong is all Engineering Project Manager in the economy vector network analyzer section of the Network Measurements Division of Hewlett Packard Company, located in Santa Rosa, California. He graduated from Oregon State University (BSEE) and Columbia Universtiy (MSEE). With HP since 1968, projects included development of microwave microcircuits, devices, and components for HP component products and microwave instruments. www.HPARCHIVE.com Introduction: RF characterization of fiber optic components is becoming more necessary as system modulation rates increase to microwave frequencies. RF network analyzers have been used to characterize electronic components for RF MEASUREMENTS years and are becoming more commonplace. OF Additionally, network analyzers with suitable optical converters can be used
