The quest for higher spectral efficiency and data rate made possible by coherent techniques has to face the problem of fiber nonlinearities. Today, any design based on advanced techniques requiring knowledge of the statistical properties of the received signal is carried on either by simply neglecting the ensuing of nonlinearities or on simplifying assumptions. Moreover, major conferences on optical communication are generally focused on technological rather than theoretical aspects. This workshop aims at laying special stress on in-depth theoretical investigation about the impact of fiber nonlinearities in coherent optical communication systems.

Submit a paper to TIWDC2015

Authors are encouraged to submit full papers to the Tyrrhenian International Workshop on Digital Communications 2015, describing original, previously unpublished research results, not currently under review by another conference or journal, addressing state-of-the-art research and development in the area of "Fiber Nonlinearities in Coherent Optical Communication". All submissions will be peer-reviewed and judged on correctness, originality, technical strength, significance, quality of presentation, and relevance to the topics of interest.

The Conference papers will appear in IEEE Xplore.

Authors of regular papers must submit their paper(s) (3 or 4 pages using the IEEE conference template) using the EDAS online application. Authors of invited papers must submit their paper(s) using the EDAS dedicated online submission application.


Formatting checks are enforced in the submission phase for manuscripts.
In particular:
1) all fonts are required to be embedded in the PDF file;
2) bookmarks are not allowed in the PDF file;
3) links are not allowed in the PDF file.

Please allow extra time to fix any formatting errors to generate a compliant file. Your final paper is planned to be included in IEEEXplore for archival value after the conference. However, IEEE reserves the right to exclude an acceptance paper from inclusion in IEEEXplore if it is not presented at the conference.

Topics of interest include, but are not limited to, the following:


For each accepted regular paper at least one of the authors is required to be registered at the "Regular", "IEEE member" or "Student" rate. For authors with multiple accepted papers, one registration is valid.

Note that TIWDC2015 registration is included in PS2015 registration
