Publ. 930 196 pages (September 1998) C0DEN:NSPUE2 Preface This year marks the 10th biennial Symposium on Optical Fiber Measurements, held September 15-17, 1998 at the laboratories of the National Institute of Standards and Technology in Boulder, Colorado. Over these last 20 years, the SOFM has been a good indicator of the issues that concern the fiber optic measurement community. At first glance, the second day's multimode fiber measurement talks may seem like a trip back in time to an SOFM from the eighties. However, recent events have brought multimode fiber issues back into the measurement arena. Polarization-mode dispersion (PMD) continues to be a topic of much interest with two full sessions devoted to a variety of subtopics in the field. Fiber geometry has several contributions, as does the broad topic of fiber mapping with length (including such parameters as chromatic dispersion and polarization properties). This year's Symposium consists of 44 papers (10 invited and 34 contributed), and continues to show a strong international participation, with two-thirds of the papers originating outside the United States.
