IRCPhoNeT

• IRCPhoNeT was created in Pisa, Italy, in March
  2001 to answer a major demand for integrating
  education, basic and applied research in the area
  of optical networks and technologies. IRCPhoNeT
  is the result of a joint effort of Scuola
  Superiore Sant'Anna, Pisa, with its Centre of
  Excellence for Information and Communication
  Engineering (CEIIC), and of CNIT (Consorzio
  Nazionale Interuniversitario per le
  Telecomunicazioni), with its National Laboratory
  for Photonic Networks (LNRF), in collaboration
  with former Marconi Communications (now
  Ericsson).

IRCPhoNeT
Funding comes from various sources Italian
Government, industrial partners and European
Commission. The Centre is actively participating
in European Cooperation actions in Scientific and
Technical Research (COST), Network of Excellence
and Integrated Projects of the 6th European
Framework Program.
