High-speed switching and optical wdm subscriber network technologies for broadband integrated services network
Shiro Kikuchi, Naoaki Yamanaka, Hideki Kataoka · International Symposium on Switching · 2005
State-of-the-art high-speed switching and optical WDM subscriber network technologies for a broadband integrated services digital network are described. A broadband network architecture dial is integrated by optical wavelength division multiplexing of STM and ATM digital signals and the analog RF subcarrier is proposed. Attainable switch and switching network sizes for time division, space division and ATM switches are determined from high-speed device trends. An expandable switch LSI and module architecture for time division and space division STM switching networks is proposed. A 2-Gb/s STM switching LSI, a 620-Mb/s STM switching module a 2-Gb/s ATM switching LSI, and their multi-case and multi-chip packages are described.
