Advances in UWB optical fibre communications: potential, challenges, solutions. 18-19 May 2023

About the event

This 2nd International AiPT Workshop will address the key challenges in optical communication emphasizing on band-limited optical transmission systems. Moving beyond the existing DWDM bandwidth, data scaling with novel technologies such as MBT, SDM and super channels over coherent optics can be a crucial way forward to meet the data demands. The proceedings will involve technical discussion on the state-of-the-art coherent technologies including experts from both academic and industrial backgrounds, addressing the potential of capacity enhancement in perspective of novel fibre (Corning, Southampton University), network equipment and sub-system development (Infinera, Nokia Bell Labs, ADVA), intelligent data processing (Fraunhofer HHI, Bristol University), network operation (British Telecom, Deutsche Telecom), and others.

The workshop will provide a strategic direction for tackling challenges in coherent optical communications, creating a bridge between academic and industrial partners to tailor novel research for the development of next generation optical networks.

Date: 18-19 May, 2023
Venue: MB653, Aston University. In person only event!
