| Abstract | Absolute laser frequency assignment in projected dense wavelength division multiplexing (DWDM) networks has become a very important issue for standardization purposes. Recently, a proposal was made to the International Telecommunication Union suggesting a set of standard wavelengths in the 1550 mn communications band. It recommended the use of a krypton line at 193.68625 THz as an absolute frequency reference and a set of 32 wavelengths evenly spaced by 100 GHz around that value. In this paper, we propose the use of an optical frequency scale with markers at exact multiples of 100 GHz for standardization. Our proposed scale is independent of the atomic or molecular species used for calibration (and thus accessible to any user), and moreover is uniformly applicable to all spectral regions. We show one way of implementing such a scale in the 1550 nm band through the use of an absolutely calibrated Fabry-Perot resonator set with a free spectral range of 100 GHz. |

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.
