Fiber Design and Processing (Chapter 4) The design and processing of fibers for special applications are presented in Chapter 4, by David J DiGiovanni, Donald P Jablonowski, and Man F Yan Erbium-doped silica fibers for amplifiers at 1550 nm, which are described in detail in Chapter 2, Volume IIIB, are covered first Rareearth-doped fluoride fibers for 1300-nm amplifiers are described later, as are fibers... attenuated and distorted data pulses, electronically reconstituting them, and then optically transmitting the regenerated data into the next transmission span.-? The EDFA is an optical amplifier that faithfully amplifies lightwave signals purely in the optical domain EDFAs have several potential functions in optical fiber transmission systems They can be used as power amplifiers to boost transmitter... that even for power amplifiers, the erbium-doped fiber is designed with a smaller core and a higher refractive index difference between the core and cladding than for standard transmission fibers E COUPLING LOSS The mismatch between the smaller optical modes of erbium-doped fibers (typically 2-4 p m in diameter) and the larger modes of transmission fibers (typically 8-10 pm) poses the challenge of... system implications of remnant birefringence in fibers Dispersion Compensation for Optical Fiber Systems (Chapter 7) Lightwave systems are not monochromatic: chirp in lasers leads to a finite range of wavelengths for the transmitter in single-wavelength systems whereas WDM systems intrinsically cover a wide spectrum At the same time, the propagation velocity in fiber is a function of wavelength that 6 Ivan... can be controlled to some extent by fiber design, as noted in Chapter 4 To avoid pulse broadening, it is necessary to compensate for this fiber chromatic dispersion Various approaches for dealing with this problem are presented in Chapter 7, by A H Gnauck and R M Jopson Additional system approaches to dispersion management by fiber planning are given in Chapter 8 Fiber Nonlinearities and Their Impact... technology After reviewing optical transparency, it treats WDM rings for local networks, metropolitan distribution, and continental undersea telecommunications (AfricaONE) Then it reviews several multi- 1 Overview 9 access test beds designed by consortia organized with partial support from DARPA (Defense Advanced Research Projects Agency) VOLUME I I B Erbium-Doped Fiber Amplifiers for Optical Communications... there: low-loss vapor-phase silica fiber and double-heterostructure lasers Although a few system trials took place beginning in 1979, it required several years before a commercially attractive lightwave telecommunications system was installed in the United States This was the AT&T Northeast Corridor System operating between New York and Washington, DC 1 OPTICAI FIBER TELECOMMUNICATIONS V O I L'ME IIlB .
