| Abstract | In this paper, we investigate an optical multicarrier source to achieve 160 Gb/s by wavelength using Polarization Multiplexing-Differential Quadrature Phase Shift Keying (POLMUX-DQPSK) and Dual Carrier-Differential Quadrature Phase Shift Keying (DC-DQPSK) with 33RZ (Return-to-Zero) pulse carving and coherent detection. The optical multicarrier source is generated by the means of a Dual-arm Mach-Zehnder Modulator (MZM) fed by a sinusoidal signal in order to generate an Optical Flat Comb Source (OFCS) spaced by the driven sinusoidal frequency. We compare the performance of the both configurations to the conventional single polarization 33RZ-DQPSK and Non-Return-to-Zero-On Off Keying (NRZ-OOK). We discuss their back-to-back receiver sensitivity and required Optical-to-Noise Signal Ratio (OSNR) for $10^{-9}$ Bit Error Rate (BER). We find, in back-to-back configuration, that 33RZ-POLMUX-DQPSK has the best receiver sensitivity and the least penalized format in terms of OSNR. We study also the robustness of these optical modulation formats against the optical fibre impairment. We find that 33RZ-DC-DQPSK has the best behaviour. |

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.
