Moving toward all-optical networks

چکیده
The first generation of optical networks employed primarily static point-to-point WDM systems to provide increased network capacity. Optical networks using WDM are now widely deployed in carrier networks, particularly in long-haul networks. For the most part, these point-to-point WDM systems provide tens of wavelengths worth of capacity over a single fiber pair, with each wavelength operating at OC-48 (2.5 Gbits/sec) or OC-192 (10 Gbits/sec). These networks were primarily statically configured with transponders and multiplexers, creating "dumb" optical pipes between locations.

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...
متن کاملAsymmetric Friction of Nonmotor MAPs Can Lead to Their Directional Motion in Active Microtubule Networks
Diverse cellular processes require microtubules to be organized into distinct structures, such as asters or bundles. Within these dynamic motifs, microtubule-associated proteins (MAPs) are frequently under load, but how force modulates these proteins' function is poorly understood. Here, we combine optical trapping with TIRF-based microscopy to measure the force dependence of microtubule intera...
متن کاملRestoration Design in IP over Reconfigurable All-Optical Networks
Large IP backbone networks today are mostly deployed directly over sequences of point-to-point DWDM systems or chains of newer ROADM-based ultra long haul systems, interconnected by OEO regenerators. The next generation core optical network is moving toward an all-optical network architecture that is based on multi-degree ROADMs to reduce OEO regeneration cost as well as enabling automatic reco...
