A Quantum Access Network Suitable for Internetworking Optical Network Units

Knowledge Network Internetworking

The convergence of informatics systems and media systems has caused a lack of educational concepts for long-term knowledge. We assume that gaining informatics competencies enables adults to meet the demands of today’s society. Therefore, didactics of informatics has to contribute educational concepts. In this paper, we introduce a strategy to structure the domain Internetworking. Aim of our res...

Technologies for Next Generation Optical Access Network

Introduction of the GE-PON system has accelerated the use of FTTH in Japan, changing the access network from simply an Internet connection to a social infrastructure that provides services directly related to daily life, such as IP telephone service. Mitsubishi Electric has the largest share of the GE-PON market in Japan and is now working on the next generation GE-PON. The role of the NGN is b...

A CDMA Secure Optical Access Network

We propose a CDMA network implementation that enhances security at the physical layer. By using an active star topology supporting both point-to-point and point-to-multipoint communication, 128 ONUs can transmit simultaneously at rates of at least 12 Mbps, with a reach of 20 km, thus addressing access network applications. Numerical simulations demonstrate the feasibility of the proposed scheme...

An Optical Network Infrastructure Suitable for Global Grid Computing

This paper presents a novel Grid network scenario based on an optical infrastructure using optical burst switching. The functional blocks required are identified as Core Router the Grid User Network Interface and the Grid Resource Network Interface. The details of the associated challenges in terms of functionality and technology are discussed and solutions are proposed.
