Energy efficient TWDM multi-PON system with wavelength relocation

Abstract Power consumption in current communication networks including the access networks is increasing rapidly; energy efficiency is therefore one of the key design considerations in the next generation passive optical networks (PONs). In this paper, we investigate how a wavelength relocation mechanism can reduce power consumption and deployment cost of transceivers in time and wavelength division multiplexed PONs (TWDM-PONs), in which wavelengths and transceivers can be shared among multiple PONs. We analyze how the percentage of deployed wavelengths and transceivers will impact the average available bandwidth and cause extra delay for the working optical network units (ONUs). We show through simulation that under typical ONU online profiles, the percentage of wavelength and transceivers that need to be deployed can be reduced to as low as 30% as compared to conventional PONs, with no resource sharing and wavelength relocation.

About National Digital Library of India (NDLI)
NDLI logo

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.
