| Abstract | Recently, considerable interest has been attracted by the evaluation of performances of optically-amplified fiber links, in which noise and saturation of the optical amplifier (OA) as well as fiber non-linearities interact to determine the evolution of the S/N ratio along the line. In this work we also include the vacuum field noise, added by the lossy fiber, and take into account the Parametric Gain (PG) that the signal generates on it. To calculate the evolution of the noise spectra along an optically amplified line, we describe the OA by means of a recent semiclassical noise-model: the amplifier is modeled as a four port device, with an idler port opened to the vacuum field; the fiber is similarly modeled as a beamsplitter with transmittance equal to its attenuation. The saturation of the OAs is taken into account by a simple phenomenological description. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
