Abstract

Substantial needs for broadband communications networks have been increasing with the advent of new technology and growing interest in visual information services. Optical switching systems and optica1-fiber transmission systems will be indispensable to realize future broadband communications networks. In particular, wavelength-division (WD) switching system and wavelength-division multiplexed (WDM) transmission systems, making full use of extremely high optical carrier frequencies and enjoying widely ranging bit-rate independency for individual channels, have potential capability for extension to wide-area broadband networks. This paper proposes optical broadband network architecture using WD switching systems and WDM transmission systems.
