Recent years have seen an exponential increase in demand for large bandwidth and high data rate applications. This is fuelled by rapid advances in fiber-optic communications which includes introduction of digital signal processing (DSP) algorithms combined with coherent detection. A thorough grounding in optical fibers and fiber-optic communications is necessary to communication engineers to address future needs of high data rate communications. Fiber-Optic Communication Systems and Techniques provides solid background in wide ranging topics of fiber-optics. The topics covered include modes of optical fibers, impairments in optical fiber channel, lasers and photodiodes, optical amplifiers, WDM components, and digital fiber-optic communications. Several latest advances in DSP for fiber-optic communications is emphasized.
