The 18th European Conference on Network and Optical Communications - NOC 2013 and the 8th Conference on Optical Cabling and Infrastructure - OC&I 2013 will be held in Graz, Austria, from July 10–12, 2013. Through its technical program, the conference will provide an opportunity for the academic and industrial communities to address new research challenges, share solutions and discuss issues in information and communication technology (ICT) referring to modern telecommunications. The 18th NOC continues to combine the 8th OC&I within a single event, providing a forum for the promotion of new opportunities from industry, institutes of technology and academia. We therefore invite you to contribute to the event through involvement as co-sponsor, session organiser, presenter, delegate or contributor. Graz is the capital city of Styria in the southeast corner of Austria. It is located in between rolling hills, to the north, east and west, only open to the south. The Old Town in Graz is one of the best preserved city districts in Central Europe and listed in the UNESCO World Heritage List. Graz’s architecture is dominated largely by the struggle of the Reformists and the Habsburgs’ Counter Reformation. A significant landmark of the city is the romantic Uhrturm (Clock Tower), situated on top of the Schlossberg mountain, with a clock still using its original mechanism from 1712. Today Graz is the second largest city in Austria and home for around 230.000 people. It offers a great deal of cultural events, like the “Styriarte”, an annual exhibition, dedicated to contemporary art, theatre and performing arts. The goal of the conference is to present high-quality results in the field, and to provide a framework for research collaboration through focused discussions that will designate future research efforts and directions. In this context, the program committee will accept only a limited number of papers that meet the criteria of originality, presentation quality and topic relevance. NOC and OC&I have reached the highest level of quality, which is reflected both in the level of participation as well as the acceptance ratio and the amount and quality of submitted papers.
