OATM/WDM Optical Access Network Using Header Decoder-Based Router for Next-Generation Communications

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...

Next Generation of Optical Access Network Based on Reflective-SOA

Communication networks have evolved in order to fulfil the growing demand of our bandwidth-hungry world. First, the coaxial cable has replaced the copper cable since 1950 for longand medium-range communication networks. The Bit rate-distance product (BL) is commonly used as figure of merit for communication systems, where the B is the bit rate (bit/sec) and L is the repeater spacing (km). A sui...

Optical-Router-Based Dynamically Reconfigurable Photonic Access Network

A flexible router platform for next generation network services

Autonomous services need a flexible router platform that provides the mechanisms to install, modify and remove services at run-time of the node without interfering with others. Instantiated services must have the ability to re-configure themselves and to exchange service functionality on demand. Envisioned router platforms must be able to run multiple services in parallel and are required to sc...

An Architecture for IP-based Next Generation Radio Access Network

High call volumes due to novel mobile data applications necessitate development of next generation wireless networks centered on high performing and highly available radio access networks (RANs). In this paper, we present an innovative IP-based wireless routing architecture (for a RAN) with mechanisms for seamless handoff operations and high Quality of Service (QOS). Algorithms for dynamic conf...
