| Abstract | Using distributed feedback laser diode (DFB-LD) in a high-speed transmission system, the chirp effect in the LD is a factor limiting transmission span length. We discussed the impact of fiber chromatic dispersion on this system performance at 10-Gb/s due to LD chirp effect. For the dispersion range of −3.51 to 2.97 ps/nm·km, negative power penalties have been observed due to the pulse compression effect, which is resulted from a low chirp of DFB-LDs. We evaluated 10-Gb/s directly modulated DFB-LDs wavelengths from 1275-nm to 1350-nm of power penalties versus transmissible standard single-mode fiber (SMF) distance. The calculated power penalties are less than 1 dB for 20-km SMF transmission. Furthermore, we also achieve a bidirectional CWDM-PON system covering a wide wavelength of 1.3-µm and 1.5-µm with an aggregated data rate of 40-Gb/s is proposed and experimented. Four uncooled direct-modulated DFB-LDs with wavelengths of 1275-nm, 1300-nm, 1325-nm, and 1350-nm are adopted for the upstream transmission to lower the installation cost and dispersion effect. Another four external-modulated lasers by LiNbO3 modulators with wavelengths of 1510-nm, 1530-nm, 1550-nm, and 1570-nm are deployed for the downstream transmission to minimize the chirp effect. These lasers are operated at 10-Gb/s simultaneously for transmission over 10-km SMF. Downstream and upstream data of high capacity are operated at 10-Gb/s per channel simultaneously. This CWDM-PON network enables client's maximum subscribing bit rate to 10-Gb/s and the splitting ratio can vary from 1:4 to 1:64. |

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.
