Here is a demonstration of the Open Disaggregated Transport Network (ODTN) with the EdgeCore Cassini White Box Transponder. The ODTN project is an operator-led initiative to build data center interconnects using disaggregated optical equipment, open and common standards, and open source software. ODTN aims to drive innovation and become the optical network of choice by disaggregating the components of the network and providing open software to control a multi-vendor assembly of components.
