Abstract

We report an industry leading optical dense wavelength division multiplexing (DWDM) field trial with line rates per channel exceeding 1.66 Tb/s using 130 GBaud dual-polarization probabilistic constellation shaping 256-ary quadrature amplitude modulation (DP-PCS256QAM) in a high capacity data center interconnect (DCI) scenario. This research trial was performed on 96.5 km of field-deployed standard single mode G.652 fiber infrastructure of Deutsche Telekom in Germany employing Erbium-doped fiber amplifier (EDFA)-only amplification. A total of 34 channels were transmitted with 150 GHz spacing for a total fiber capacity of 56.51 Tb/s and a spectral efficiency higher than 11bit/s/Hz. In the single-channel transmission scenario 1.71 Tb/s was achieved over the same link. In addition, we successfully demonstrate record net bitrates of 1.88 Tb/s in back-to-back (B2B) using 130 GBaud DP-PCS400QAM., Comment: This work has been submitted to the IEEE Photonics Technology Letters (PTL) for possible publication

17. SplitArchitecture: Applying the Software Defined Networking Concept to Carrier Networks.

Author

Kind, Mario, Westphal, Fritz-Joachim, Gladisch, Andreas, and Topp, Steffen

Abstract

Software Defined Networking (SDN) and OpenFlow in particular has a lot of interest in the research and the academic communities. The SDN concept evolves current design philosophies and could be assumed as one approach of a future clean slate internet design. Nonetheless, the concept requires some advancement for integration in a carrier network environment. The ICT project SPARC, funded by the European Commission, is developing a SplitArchitecture concept in order to close this gap. Based on typical use cases, requirements have been derived and integrated in the process of developing the concept. The service creation for residential customers in access/ aggregation networks is a first result. Moreover an overview on the improvements by SplitArchitecture for carrier networks is provided.

Abstract

Optical systems and technologies have been radically changing the telecommunication networks for past 15 years; today wavelength division multiplexing (WDM) technology, optical amplifiers, and simple optical switching elements like optical add-drop multiplexers (OADMs) are used in the backbone networks of all operators worldwide. Optical systems nowadays provide the basis for cost-effective transmission of large amounts of bandwidth over the Internet. and will enable its future growth and the spreading of new applications and services. This paper summarizes the main trends in optical networking and investigates potential future application areas. Optical system technology has become so pervasive in network design that it needs to be considered in the context of provisioning new applications and services. Therefore, the analysis is not limited to the aspects of physical transmission, but also takes into account recent developments in integrated network design as well as network control and management. The following sections describe the key functionalities of future optical network architectures, and the key findings of the theoretical analysis are supported by the results of a field trial of advanced transmission technology.
