ACKNOWLEDGEMENTS
Theidea for writing a monograph on the subject of fiberoptic data communications was proposed to me
manytimes by my assistant, GailNelson.
Thematerial in this work was derived from my constantperusal of many diversesources spread over my
years in engineering. I apologize fornot providing a preciseacknowledgment of every source. However,
it would have led to a clutter of footnotes. I know thatthis often makes fortedious reading and didnot
want to burden the reader. Nonetheless, I would not feel comfortableunless specific credit is given to
those publications listed as 'References.' If, on occasion, I paraphrased any of theseworks too closely it
should be taken in the mostcomplimentary manner.
PatO'Hara assisted me in taking a typed manuscript and putting it in final form complete withgraphics,
photographs and other illustrations. Pat carries out this task for all of my publications. Shenever
complainswhen I come to her with lastminute changes. Her cooperation is really appreciated. I can
truthfully say this work would nothave been completed withouther assistance. Note to Pat,we'll soon
beginanother effort.
Thanks to Doug Honikel for havingincorporated this onto ourwebsite.
Tony Horber and Bob Ravenstein(Bomara, Inc.) checked thework for technical accuracy.This was a
particularlystressful task especially when it led to protracted discussions on certainpoints. I am
indebted to them for theirefforts.
Professor Nicholas DeClaris firstintroduced me to communicationsengineering while I was an
undergraduate at Cornell University. Professor DeClaris, now of theUniversity of Maryland,inspired
me with his love forteaching and research. Dr. IrvinStiglitz later sharpened my communications
engineering and technical writing skillswhile he was my Group Leader at M.I.T. Lincoln Laboratory.
Needless to say, it is a lot easier to reach Irv's high standards these days with word processing.
Thanks to Lightwave Magazine and MRV Communications for use of the illustration for thecover.
Finally, I would like to thank my wife, Diane, my childrenAndrew, Jessica and Rachel, my mother and
father,Lillian and Irving Schneider and my, close, life long, friends Seth Stowell, Jamil Sopher and Joel
Goldman. In different ways each gave me encouragement over the years. Without this support I would
havenever have reached thispoint.
