“…[6], are gradually arising. Although at a higher complexity cost, algorithms which include physical layer limitations may bring additional benefits such as reductions in overall system cost [7], [8]. Nevertheless, channel mutual influence due to non-linear effects and transient effects during signal propagation in optical fibers and optical amplifiers, respectively, are yet to be considered.…”

This work presents a study on impact of Four Wave Mixing in dynamic optical networks. A simple algorithm is proposed in order to manage Four Wave Mixing impairments. Numerical results regarding blocking probability suggest that wavelength assignment should favor the wavelength with the smallest amount of noise. The limits for the use a simple greedy algorithm are tested. Although the algorithm clearly fails when network is severely impaired by FWM, significant improvements are achieved for low and moderate levels of FWM.

“…Based on the physical impairment information, the optical signal quality can be estimated or measured. One way to provide QoT is to bound the LSP length to the maximum transparent distance (referred to as "QoT distance" hereafter) [16,17]. An alternative is to estimate or analytically compute the optical signal quality using a single or a set of physical performance indicators (such as the optical signal-to-noise ratio (OSNR), the estimated bit error rate, the Q factor) [5,18].…”

To exploit the sharing benefits, the scarce regenerators are used for both regeneration and wavelength conversion (WC) leading to a sharing of functionalities. Also, the shared path protection mechanism is exploited to ensure survivability against single-link failures and make the sharing of network resources (regenerators and wavelengths) possible. The paper presents a novel distributed scheme (DISTR) for reservation of regenerators and wavelengths in generalized multi-protocol label switching controlled WSONs, in order to ensure the required level of QoT and survivability. Novel objects and selection strategies for the resource reservation protocol with traffic engineering extensions are proposed and evaluated. The DISTR scheme effectively combines regeneration and WC points, leading to a noticeable reduction of the regeneration usage with respect to the existing schemes. Moreover, a significant reduction of the blocking probability is achieved, independently of the wavelength selection strategy used.

“…Then, in the current circumstance, the nonlinear effects and linear dispersion are compensated separately. A lot of papers pay great attentions on the combined effects of chromatic dispersion and self-phase modulation [1][2][3][4][5][6]. Second we had presented a new perturbation method for the nonlinear Schrödinger equation to study signal-noise interactions in amplified multi-span fiber-optic systems [1].…”

In this paper, an optical time-domain fractional Fourier transformation (FRFT) system is proposed to achieve the minimum distortion transmission under combined effects of chromatic dispersion and self-phase modulation (SPM). In the new method, the pulses operated as FRFT will propagate in a new domain, in which the waveform in time domain will keep nearly unchanged through the transmission. The novel method achieves a 400 km optical transmission for an optical pulse with the full width at the 1/e point of peak power of 80 ps without any dispersion compensation and the pulse offers a nice performance with negligible nonlinear distortion. Compared with the soliton communication, this scheme shows more advantages on linear and nonlinear distortions without strict restriction to input pulses.
