Panel: The Importance of “Open Transport” DCI Innovations in the Evolution of Metro and Long-haul Optical Networks

Tuesday, 5 March, 12:15-13:45

Theater II, Hall E
 

Panel Description:

The capacity of the transport networks interconnecting data-centers (DCI) has grown more than any other traffic type this decade, motivating the evolution of packet and optical transport, and even of the Internet transport architecture.  Purpose-build DCI transport has achieved some of the most spectrally efficient WDM transmission deployments globally, currently exceeding 5 b/s/Hz, and has also pioneered “Open” transport architectures. 

 

The introduction of “open” optical transport architectures, which allow network operators to scale employing technologies from different optical system vendors that interoperate over the same fiber, has been one of the most widely debated topics in OFC the last 3-4 years.  It was initially proposed for inter-DCI transport, but it has since been increasingly adopted by many network operators, globally, and is currently considered as an important recent transport network evolution. It has also motivated multiple significant system and network innovations.  Most notably, “open” optical transport architectures have been extensively combined with the adoption of significant software innovations in network programmability, automation, control-plane disaggregation, and management abstraction, collectively usually referred to as “SDN”.  At the same time, flex-spectrum WDM systems and coherent transmission have also been instrumental for “open” optical transport.  

 

This panel will debate the adoption and main similarities and differences in open transport architectures for Inter-Data-Center, Metro and Long-Haul optical networks, and review the most important related innovations that enable the “open” optical transport evolution.  Among the many interesting related topics, this panel will particularly discuss:

• The main requirements of the new open transport network architectures,  

• The adoption, similarities and differences in open optical transport evolution among Inter-Data-Center, Metro and Long-Haul Networks,    

• The current and emerging technology innovations (hardware and software) for “open” optical transport.
