Creating and sharing knowledge for telecommunications

Project: Terminal Optical Equipments for Single Side Band

Acronym: ETOBLU
Main Objective: Chromatic dispersion in nondispersion-shifted fibers, limits significantly the transmission distance in optical systems operating at data rates in the range of 10Gbit/s, or higher, per wavelength division multiplexing (WDM) channel. This limitation is due to intersymbol interference (ISI), which leads to degradation on system performance. Given the large quantity of nondispersion-shifted fibre currently installed in telecommunications network, overcoming this limitation has become a very important scientific and commercial goal.
One of the most promising techniques to overcome the dispersion limit is the transmission of optical single sideband (OSSB) signals. This project will develop OSSB transmission and receiver systems capable to upgrade the capacity of the installed fibre with transmission rates exciding the 10 Gbit/s.
