OPTICAL-5G - High-Capacity SDM Solutions for Optical Backhaul in 5G Networks and Optical Data Center Connectivity




OPTICAL-5G is an IT internal research project that relies in a close cooperation between the

Optical Communications and Photonics Group (OCP-Av) at IT Aveiro and the

Optical Communications and Photonics Group (OCP-Lx) at IT Lisbon.


By introducing an additional orthogonal multiplexing dimension, the space, along with advanced modulation formats we are proposing optical backhaul solutions with very-high capacity, spectral efficiency, and energy efficiency, and low cost per bit. Such kind of solution will reveals of most importance to face the increasing bandwidth demand and challenging requirements arising from new applications in very high capacity future 5G networks.



This project embraces the investigation of enabled optical networks based on spatial division multiplexing (SDM) for optical backhaul in 5G network infrastructure and data center connectivity. The SDM analysis is going to comprise the investigation of very high capacity optical systems supported by multicore (MCF) and few-mode fibers (FMF), complemented by advanced digital signal processing (DSP) techniques and free-space optical (FSO) connections.





Instituto de Telecomunicações

The Instituto de Telecomunicações (IT) is a private, not-for-profit organization, of public interest, a partnership of nine institutions with research and development in the field of Telecommunications


IT mission is to create and disseminate scientific knowledge in the field of telecommunications.


IT is actively involved in fundamental and applied research both at national and international levels. Simultaneously it is committed to foster higher education and training, by hosting and tutoring graduate and postgraduate students. it also plays its role towards public society with public awareness initiatives, knowledge transfer to industry, and by providing consulting services on a non-competing basis.
