 The title: “Why and how to build open public FTTH networks – the Lower Austrian model” 


Abstract: In theory its called the 3LOM-Model, when separating the passive, active and service layer of a telecommunication network. Lower Austria as the biggest Austrian province with the most sparse populated countryside is realizing the 3LOM-Model for a sustainable solution of broadband coverage. The practical implementation is called the Lower Austrian model and this work is giving details about considerations and realization aspects of organizing, financing and implementing one of the most important infrastructure project of the public sector in the years coming. It’s also a blueprint for solving the issue of comprehensive broadband coverage in rural areas.

"Optical access networks deployment in Croatian telecommunications market" 


Abstract: Optical access network development in Croatia has been put into a global as well as in the European Union context. All the challenges and the driving factors for optical access networks deployment are considered. Optical access network architectures that have been deployed by most of the investors in Croatian telecommunication market are presented, as well as the architectures that are in early phase of deployment.

Abstract: To enable a significantly reduced footprint directly modulated lasers (DMLs) have been proposed instead of large external modulators. However, it is challenging to use DMLs due to their low dispersion tolerance and limited achievable extinction ratio (ER). A promising solution to this problem is optical spectral reshaping (OSR) since it is possible to increase the dispersion tolerance as well as to enhance the achievable ER for both on-of-keying and 4-pulse amplitude modulation (PAM) signals. However, moving to 4-PAM, many of the impressive demonstrations reported so far rely heavily on off-line digital signal processing (DSP), which increases latency, power consumption and cost. We are going to review recent numerical and experimental results on OSR for 4-PAM to increase baudrate•distance product.

The title: Network Virtualization for Cloud Radio Access Network (C-RAN)


Abstract: Through the network virtualization, a number of Base-Band Units (BBUs) can be grouped together to form a BBU pool to support a large number of Remote Radio Heads (RRHs). Such a mobile front-haul technology is essential for a Cloud Radio Access Network.

The advent of the next generation Passive Optical Network (PON) technology, such as XGS-PON and NG-PON2, makes the satisfaction of the requirement in strict timing constraint and delivering capacity imposed by mobile front-haul networks to become reachable. The emergence of virtualized Optical Line Termination (vOLT) makes virtualized Access Networks to become feasible. The combination of next generation PON technology and vOLT scheme would form the foundation of the future C-RAN infrastructure.
