| Abstract | Several approaches have been proposed in order to solve the adaptive control of optical amplifier operating point problem (ACOP). These approaches aim to adjust the gain of each amplifier in a cascade of amplifiers. Some previous results show that it is possible to decrease the noise added by the amplifiers by using these strategies. However, the configurations found by these approaches may degrade the quality of the transmission due to nonlinear effect, because the amplifiers may operate with a high output power. Therefore, the goal of this work is to analyze the impact of the nonlinear effects in the solutions found by these approaches by evaluating the BER of a system that uses a very sensitive modulation in terms of OSNR (64QAM). We tested LossComp, WAdGC and AsHB approaches in a system with 40 channels, using 50GHz fixed grid and considering high and low system input powers. The results showed that for all analyzed approaches the system quality of transmission is affected by the nonlinear effects, and the effect is worse in those with higher amplifier output powers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
