Optics: Shine A Light: Optics: Shine A Light
- Gloria Vuagnin (GARR)
Description
The optical transmission environment is changing. The fixed grid single-vendor solutions are giving space to flex grid, open and programmable optical line systems that enable the transmission of signals from various light sources.
New opportunities are opening up for the provision of innovative services, some of which will be presented in this session. All presentations will focus on spectrum sharing among different domains at an international level, showing the state of the art in creating high bandwidth and Time&Frequency services.
Ideally, NRENs should be able to interwork with each other at the optical level to support efficient exchange of high-bandwidth information, which is vital to their collective mission. The presentation contrasts two approaches to achieve this.
One approach uses two flavours of spectrum sharing – spectral pipes and spectrum slicing – that allow a guest-NREN to control use of spectrum from a...
Recent advances in optical networks led to redefine interconnections as slices of optical spectrum. To allow the research networking community to make use of these new technologies, the spectrum service team in GN4-3-WP7T2 have completed a Spectrum Service definition, created a reference model and evaluated optical modelling tools. In 2021 GÉANT ran pilots on several links. In 2022 the team...
This presentation will discuss the current state of time and frequency networks in different European countries and present the need for European time and frequency dissemination networks. In this presentation we will discuss our current understanding of the needs of European science and society for accurate time and frequency broadcasting over fibre, the currently existing infrastructures as...
