Demonstration of optical communication network for ultra high-definition image transmission

Abstract

In order to overcome the limitation of low-power-consumption and communication capacity of the equipment forming the present communication network, National Institute of Advanced Industrial Science and Technology (AIST) has carried out a demonstration of a new prototype optical path network to support the super HD large-capacity image contents era, in collaboration with five IT- related companies and with the support of National Institute of Information and Communications Technology (NICT) and Nippon Hoso Kyokai Science and Technology Research Laboratories (NHK/STRL) . The experiment was a trial to demonstrate the performance of the dynamic optical path network developed mainly by AIST under practical conditions, using a network testbed of field optical fiber links connecting Akihabara, Otemachi and Koganei offices in Tokyo. The demonstration included the cross-border-connection with the optical packet and circuit integrated network realized by NICT and transmission of super HD video signals developed by NHK. In this paper, we describe the objectives, targets, technology syntheses based on the elemental technologies for the demonstration, and outcomes.
