“…Simulation results of connections accepted versus source-destination (s, d) pairs using MOBWA, four band/8 band CIOBWA with assigned wavelength being 15, 20 and 25 considering (2,8) and (4,9) as sourcedestination pairs, are presented in Figure 8 The number of accepted connections is higher for eight bands CIOBWA than for four bands CIOBWA, which in turn has higher accepted connections than MOBWA. It can be clearly concluded about how with increased assigned wavelengths; the number of accepted connections has improved for all WA techniques.…”

There has been increasing demand for connection setup with a higher quality of service (QoS) in WDM/ DWDM networks, especially in fields like radio over fiber, where phase modulation affects the link quality. Hence to meet guaranteed QoS in a phase modulated link, the effects of phase modulation on link quality are very much needed. The link quality is termed as quality factor (Q-factor). The primary objective is to use effectively the connections available to optimize the computed number of connections and reduce the blocked connections but at the same time guaranteeing QoS as per client's need. The analysis has been done by taking care of routing and wavelength assignment (RWA) techniques. The performance analysis is presented in terms of blocking probability.

Optically transparent routing of wavelength division multiplexed (WDM) channels, which is a major trend in optical networksachieving that goal, as it incorporates routing which is agnostic to the modulation format and/or the modulation rate of the routed signal. It can also contribute to decreasing global network power consumption by avoiding the unconditional use of regenerators at each network site traversed by the optical signal. However, transparency also implies an increased accumulation

“…Therefore, the development of models that use simple analytical equations is of paramount importance. Some models consider the SNR degradation or Q factor [4,16,[19][20][21][22]. Another approach is to consider the degradation of the OSNR [3,[23][24][25][26][27][28].…”

OSNR model to consider physical layer impairments in transparent optical networks

et al. 2008

We propose a model that considers several physical impairments in all-optical networks based on optical signal-to-noise degradation. Our model considers the gain saturation effect and amplified spontaneous emission depletion in optical amplifiers, coherent crosstalk in optical switches, and four-wave mixing in transmission fibers. We apply our model to investigate the impact of different physical impairments on the performance of all-optical networks. The simulation results show the impact of each impairment on network performance in terms of blocking probability as a function of device parameters. We also apply the model as a metric for impairment-constraint routing in all-optical networks. We show that our proposed routing and wavelength assignment algorithm outperforms two common approaches.
