چکیده
All-optical switching fabrics will be a significant breakthrough in order to relieve the capacity bottleneck of electronic-switched networks. These devices allow switching traffic directly in the optical domain, avoiding the need of several optical-to-electrical-to-optical conversions. In this paper, the state of the art of optical switching fabrics is reviewed, by outlining the main technologies that are under development. Moreover, some possible applications and performance data are summarized, based on a market analysis that we carried out in the latest months. We believe that this review is valuable to researchers envisaging new all-optical switching network architectures for telecommunications networks of the future. Key-Words: optical communication, Internet, switching, acousto-optic, holography, thermo-optic, optical amplifiers.

A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...
