Optical spectrum as a service (OSaaS) spanning over multiple transparent optical network domains can significantly reduce the investment and operational costs of the end-to-end service. Based on the black-link approach, these services are empowered b

Growth and Sustainability Aspects of WDM

Autor: Klaus Grobe

Internet growth leads to exponentially increasing WDM-systems energy consumption. WDM systems should be replaced by more-efficient successors after certain time to optimize related use-phase carbon emissions. These emissions are overcompensated by th

We use channel probing to determine the best transponder configurations for spectral services in a long-haul production network. An estimation accuracy better than +/- 0,7dB in GSNR margin is obtained for lightpaths up to 5738km.

QoT Assessment of the Optical Spectrum as a Service in Disaggregated Network Scenarios

Autor: Helmut Griesser, Jim Zou, Jorg-Peter Elbers, Klaus Grobe, Gert Jervan, Sander Lars Jansen, Marko Tikas, Tobias Fehenberger, Kaida Kaeval

The potential to operate third-party terminals over multi-domain transparent optical networks attracts operators and customers to implement Optical Spectrum as a Service (OSaaS). As infrastructure information cannot always be shared with OSaaS end cu

Wavelength division multiplex (WDM) passive optical network (PON) is considered for converged fixed mobile broadband access networking. We propose to utilize low-cost tunable lasers at the remote sites, together with a centralized wavelength locker.
