Demonstration of Virtualizeable and Software-Defined Optical Transceiver

In order to serve the future high-performance network-based Internet applications, optical network virtualization is proposed to offer each application type a dedicated virtual optical network (VON). Virtualizeable bandwidth variable transceiver …

SDN-Enabled Sliceable BVT Based on Multicarrier Technology for Multiflow Rate #x002F;Distance and Grid Adaptation

We propose a sliceable bandwidth variable transceiver (S-BVT) architecture suitable for metro/regional elastic networks and highly scalable data center applications. It adopts multicarrier modulation, either OFDM or DMT, and a cost-effective …

First Demonstration of Multi-Vendor and Multi-Domain EON with S-BVT and Control Interoperability over Pan-European Testbed

The operation of multi-domain and multi-vendor EONs can be achieved by interoperable Sliceable Bandwidth Variable Transponders, a GMPLS/BGP-LS-based control plane and a planning tool. This paper reports the first full demonstration and validation …

SDN-Enabled Sliceable BVT Based on Multicarrier Technology for Multi-Flow Rate/Distance and Grid Adaptation

We experimentally demonstrate multiple advanced functionalities of a cost-effective high-capacity sliceable-BVT using multicarrier technology. It is programmable, adaptive and reconfigurable by an SDN controller for efficient resource usage, enabling …

IDEALIST Data Plane Solutions for Elastic Optical Networks

The elastic optical networks paradigm offers a competitive solution in terms of resource utilization to cope with the ever-increasing traffic demand. Specifically, the ability to make a number of previously fixed transmission parameters tunable, for …

Chirp and Frequency Offset Tolerant Coherent Burst-Mode Receiver Using Directly Modulated DFB Lasers for Coherent PON Systems

Burst-mode receiver (BMR) is one of the key components in passive optical networks (PONs). When directly-modulated distribution feedback (DFB) lasers are used as transmitter source, the BMR needs to take additional measures to compensate the effects …
