“…With higher signal power, tighter channel spacing, and longer transmission distance, the limiting characteristic of optical communication becomes pulse distortion during propagation. 8 The simplest distortion arises because each optical pulse contains a small range of wavelengths, and since the refractive index of the glass varies slightly with wavelength, different parts of the pulse travel at different speeds, resulting in pulse broadening during propagation. This dispersion may accumulate to the point where each pulse extends over several bit periods and creates errors in signal detection for conventional fibers.…”

“…With the transition to 10 Gb/s transmission rates in the late 90's, dispersion compensation has become a necessary requirement for optical networks [6]. To overcome the high insertion loss of Dispersion Compensating Modules (DCMs), initially as high as 10 dB for every 80 -100 km of transmission fiber, additional optical amplification is required.…”

Recent trends in optical networks, such as Reconfigurable Optical Add Drop Multiplexing (ROADM) and optical cross connects, require advanced optical amplifiers based on both Erbium Doped Fibre Amplifiers (EDFAs) and Raman technology. To address the dynamic nature of modern networks, EDFAs should provide broadband variable gain operation, flexible mid-stage access, fast transient response to dynamic events, and advanced spectral monitoring and control to adjust to changing spectral conditions in the network. An important supplement to EDFA technology is the use of Distributed Raman Amplification (DRA) to achieve transmission over multi-span Ultra Long Haul (ULH) links in all optical networks, as well as very high loss repeaterless links.

“…being the z-dependent dispersion coefficients of various orders [1,17,25], and β (z, ω) being the ω-dependent propagation constant of optical wave in the fiber. Because of the definition in terms of derivatives, β 2 may be called the second-order dispersion (often simply dispersion in short), while β 3 may be called the third-order dispersion, so on and so forth.…”

Optical phase conjugation is demonstrated to enable simultaneous wide-band compensation of the residual dispersion and the fiber nonlinearities in dispersion-managed fiber transmission lines employing slope-compensating fibers. When the dispersion slope of transmission fibers is equalized by slope-compensating fibers, the residual dispersion and the slope of dispersion slope are compensated by middle-span optical phase conjugation. More importantly, fiber nonlinearity may be largely suppressed by arranging the fibers into conjugate pairs about the phase conjugator, where the two fibers of each pair are in scaled translational symmetry. The translational symmetry is responsible for cancelling optical nonlinearities of the two fibers up to the first-order perturbation, then a mirror-symmetric ordering of the fiber pairs about the conjugator linearizes a long transmission line effectively.
