Fiber-Optic Communication Systems by Govind P.Agrawal

Since the publication of the first edition of this book in 1992, the state of the art of fiber-optic communication systems has advanced dramatically despite the relatively short period of only 10 years between the first and third editions. For example, the highest capacity of commercial fiber-optic links available in 1992 was only 2.5 Gb/s. A mere 4 years later, the wavelength-division-multiplexed (WDM) systems with the total capacity of 40 Gb/s became available commercially. By 2001, the capacity of commercial WDM systems exceeded 1.6 Tb/s, and the prospect of light wave systems operating at 3.2 Tb/s or more were in sight. During the last 2 years, the capacity of transoceanic light wave systems installed worldwide has exploded. Moreover, several other undersea networks were in the construction phase in December 2001. A global network covering 250,000 km with a capacity of 2.56 Tb/s (64 WDM channels at 10 Gb/s over 4 fiber pairs) is scheduled to be operational in 2002. Several conference papers presented in 2001 have demonstrated that light wave systems operating at a bit rate of more than 10 Tb/s are within reach. Just a few years ago it was unimaginable that light wave systems would approach the capacity of even 1 Tb/s by 2001.
