Field Trial of a Novel SDN Enabled Network Restoration Utilizing In-Depth Optical Performance Monitoring Assisted Re-Planning

We experimentally demonstrate a monitoring scheme utilizing both intermediate node and receiver monitoring for network re-planning. Either modulation format switching or light-path re-routing is adopted for restoration. The recovered signal performs …

Software Defined Networking (SDN) over Space Division Multiplexing (SDM) Optical Networks: Features, Benefits and Experimental Demonstration

We present results from the first demonstration of a fully integrated SDN-controlled bandwidth-flexible and programmable SDM optical network utilizing sliceable self-homodyne spatial superchannels to support dynamic bandwidth and QoT provisioning, …

First International SDN-Based Network Orchestration of Variable-Capacity OPS over Programmable Flexi-Grid EON

High Order Modulation Formats for Multi-Terabit Optical Communication Systems

This paper reviews some of the recent progress in research community in increasing the spectral efficiency of optical communication systems through the use of high order modulation formats and coherent detection techniques. Some of the possible ways …
