This textbook is a guide to outside plant fiber optic construction, basically the process of installing the fiber optic cable plant including the work necessary before the fiber optic techs begin splicing, terminating and testing the cable plant. This book was written by Joe Botha of Triple Play Fibre Optic Solutions in South Africa as a textbook for classes he teaches on construction. Joe, an FOA Master Instructor, created the course to fill a need for training OSP construction crews. The book covers topics which are rare in textbooks, practical solutions to designing and installing the fiber optic cable plant. It is an extremely valuable reference book for all owners, designers, supervisors and installers of fiber optic OSP networks.

Optical fiber telecommunications depend upon light traveling great distances through optical fibers. As light travels it tends to disperse and this results in some degree of signal loss. Raman amplification is a technique that is effective in any fiber to amplify the signal light as it travels through transmission fibers, compensating for inevitable signal loss. - First comprehensive guide to Raman amplification, a technique whose use has exploded since 1997 in order to upgrade fiber capacity - Accessible to professionals just entering the field of optical fiber telecommunications - Detailed enough for experts to use as a reference
It has become obvious that high speed Internet access has become a necessity for everyone not a luxury. The best and most obvious solution, fiber to the home (FTTH, ) has become a reality and is in widespread use worldwide. This handbook is written for those who want to know more about FTTH, whether they are considering a FTTH project for their area or are involved already in planning, designing, building or operating a FTTH network already. The Fiber Optic Association (FOA) is the international professional organization of fiber optics and certifying body for fiber optic technicians. FOA has been involved with FTTH since in the early 2000s. This book began as a compilation of all the FTTH materials from the FOA Guide and FTTH CFOS/H certification curriculum and expanded with additional materials covering FTTH project design and management. The FOA materials come from almost two decades of experience with FTTH including developing training curriculum for training techs for the earliest commercial installations of FTTH and consulting with many diverse FTTH projects. This handbook is written to provide the technical information that can help a service provider understand how to start a FTTH project or a local organization decide if they want to create a do-it-yourself FTTH project run by their local government, electrical coop or a public-private partnership.
This book has been written to assist not only postgraduate students, but also int- ested dermatologists, general practitioners, and surgeons. During the last two decades, various surgical therapies have been used in the tre- ment of stable refractory vitiligo, but none of them became very popular because of their intrinsic drawbacks, and thus could not be adopted as a standard procedure. There has always been a need for a technique that gives best results without complications. The commonly used surgical procedures for the treatment of vitiligo have been narrated in short and their characteristic drawbacks have been pointed out. The c- lular graft technique is costly, requires a good laboratory and infrastructure, and except for being able to cover a wider vitiliginous area, the ultimate results are no better than tissue grafting technique. I used the small skin particles prepared from ultra thin or thin split thickness skin graft, the so called “microskin graft,” in the tre- ment of vitiligo effectively with good expansion ratio, i.e., small donor skin to treat big vitiliginous area. This procedure covers the bene? t of cellular and tissue graft, but without their inherent drawbacks. The microskin graft technique has been illustrated with minimum necessary text to explain the steps. This technique is very simple to learn and execute. It is extremely 2 cost effective and can treat very large area up to 1,500 cm in an operative session.
Nanotechnology is revolutionising the world of materials. This important book reviews its impact in developing a new generation of textile fibers with enhanced functionality and a wide range of applications. The first part of the book reviews nanofiber production, discussing how different fiber types can be produced using electrospinning techniques. Part two analyses the production and properties of carbon nanotubes and polymer nanocomposites and their applications in such areas as aerospace engineering. The third part of the book considers ways of using nanotechnology to improve polymer properties such as thermal stability and dyeability. The final part of the book reviews the use of nanotechnology to modify textile surfaces, including the use of coatings and films, in order to improve hydrophobic, filtration and other properties.Nanofibers and nanotechnology in textiles is a valuable reference in assessing and using a new generation of textile fibers in applications as diverse as tissue and aerospace engineering. - Nanotechnology is revolutionising the world of materials - Learn about a new generation of textile fibers that have a wide range of applications - Examines how to improve polymer properties
In this monograph, investigations of the performance of narrow-gap semiconductor photodiodes are presented, and recent progress in different IR photodiode technologies is discussed: HgCdTe photodiodes, InSb photodiodes, alternatives to HgCdTe III-V and II-VI ternary alloy photodiodes, lead chalcogenide photodiodes, and a new class of photodiodes based on two-dimensional solids. Investigations of the performance of photodiodes operated in different spectral regions are presented.
UV-VIS spectroscopy is one of the oldest methods in molecular spectroscopy. The definitive formulation of the Bouguer-Lambert Beer law in 1852 created the basis for the quantitative evaluation of absorption measurements at an early date. This led firstly to colorimetry, then to photometry and finally to spectrophotometry. This evolution ran parallel with the development of detectors for measuring light intensities, i.e. from the human eye via the photo element and photocell, to the photomultiplier and from the photo graphic plate to the present silicon-diode detector both of which allow simultaneous measurement of the complete spectrum. With the development of quantum chemistry, increasing atten tion was paid to the correlation between light absorption and the structure of matter with the result that in recent decades a number of excellent discussions of the theory of electronic spectroscopy (UV-VIS and luminescence sp,~ctroscopy) have been published. Consequently, this extremely ivteresting aspect of molecular spec troscopy has dominated the teaching of the subject both in my own lectures and those of others. However, it is often overlooked that, in addition to the theory, applications of spectroscopic methods are of particular interest to scientists. For this reason, a lecture series about electronic spectroscopy given in the Institute for Physical Chemistry at the Heinrich-Heine-University in Dusseldorf was supplemented by one about "UV-VIS spectroscopy and its applications". This formed the basis of the present book.
This book discusses the recent advances in the area of near-field Raman scattering, mainly focusing on tip-enhanced and surface-enhanced Raman scattering. Some of the key features covered here are the optical structuring and manipulations, single molecule sensitivity, analysis of single-walled carbon nanotubes, and analytic applications in chemistry, biology and material sciences. This book also discusses the plasmonic materials for better enhancement, and optical antennas. Further, near-field microscopy based on second harmonic generation is also discussed. Chapters have been written by some of the leading scientists in this field, who present some of their recent work in this field.·Near-field Raman scattering·Tip-enhanced Raman spectroscopy·Surface-enhanced Raman spectroscopy·Nano-photonics·Nanoanalysis of Physical, chemical and biological materials beyond the diffraction limits·Single molecule detection
