Evaluation of flexibility in hybrid WDM/TDM PONs
Introducing a WDM dimension on the top of a TDM PON system is a natural evolution to increase the capacity of an optical access network, and this can also offer additional flexibility options. Several hybrid WDM/TDM PON architectures can be...
A design method of high-availability and low-optical-loss optical aggregation network architecture
A highly-energy-efficient network using an optical aggregation network and a service cloud has been proposed to reduce the power consumption of today's Internet greatly. The optical aggregation network connects a solitary giant router to us...
A study of next generation metro-access hybrid scalable network by using PLZT ultra high speed optical wavelength selective switch
We have studied a novel optical access network with PLZT (Plomb Lanthanum Zirconate Titanate) optical switches, called ActiON (Active Optical Network), as a next generation access network to replace PON (Passive Optical Network). On the oth...
Greetings from General Co-Chairs
On behalf of the IEEE-ISAS2011 Committee, it is our great pleasure to welcome you to Yokohama City for the 1st International Symposium on Access Spaces (IEEE-ISAS2011), which is technically co-sponsored by IEEE Industrial Electronics Societ...

Performance of rapid spanning tree protocol in access and metro networks
Ethernet provides a simple and low-cost solution at high bandwidth for access and metropolitan networks. The failover performance of bridges is indispensable of their applicability. Therefore, new IEEE protocols were developed and deployed ...
On triplexer design for next generation Ethernet Passive Optical Network (EPON) systems
The standardization effort targeting 10 Gbit/s EPON systems, together with the requirement for coexistence with the legacy IEEE 802.3ah compliant equipment, impose a set of very tight requirements in terms of wavelength allocation plan for ...
