Abstract

Transmission systems employing Raman amplifier technology have to put up with much higher level of design complexities, when compared to conventional transmission lines with doped fiber optical amplifier. Even for the construction of a fundamental, basic building block - a unit of a fiber Raman amplifier (FRA), the designer have to struggle with the problems associated with the interactions between pump / signal waves mediated by Raman process, have to wander within the vast degrees of freedom given the choice of pumping directions / ratios, and have to contemplate with the wavelength dependent fiber loss / noise figure profiles. The problem further evolves into steps-higher, demanding and time-consuming one when extended to that of a system design employing Raman amplifiers. Optimizing OSNR and designing ultra-long haul links with best Q performances, while adjusting variables in the span length, Rayleigh penalty, pump noise, nonlinear penalty, dispersion and gain distribution is a problem which can be easily stated, but in reality is not a process which can be easily achieved. We present efficient, optimal design methods for Raman amplified WDM transmission links: 1. for the multi-channel gain flatness, 2. transient control under signal reconfigurations, and 3. for the estimation of optimum system Q value and corresponding link design parameters.
