Abstract
We describe a field trial of a wavelength routing full-mesh
wavelength-division-multiplexing (WDM) (AWG-STAR) network for citywide
local administration in Japan. An AWG router and five WDM nodes were
connected to the existing fiber in the downtown area of the city of
Chitose, Hokkaido. A 5 x 5 full-mesh network was overlaid on the
Chitose intranet. A video-on-demand system based on Gigabit Ethernet
links, high-definition serial digital interface signals, and synchronous
digital hierarchy signals of STM-16 links are transmitted and routed
simultaneously on the wavelength paths of the network. These systems are
used for administration and education information sharing for city
residents. The network is managed and controlled remotely from the NTT
R&D Center in Atsugi, Japan, which is 50 km southwest of Tokyo and
approximately 1000 km from Chitose. AWG-STAR exhibits promising potential
as a large capacity network system for both simple full-mesh systems and
highly secure private networks.
