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.

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
