in a nutshell

DSPMetroNet - DSP Functions for Simplified Coherent Transceivers in Optical Metropolitan Networks...
is a R&D project running at Instituto de Telecomunicações - Aveiro site - whose main objective is to investigate, develop and validate new technological paradigms in terms of optical coherent detection schemes and advanced digital signal processing (DSP) techniques to support optical coherent transceivers for future optical metro networks.

Coherent Detection

Acess to the total information of the otical field

Phase- and Polarization-Diversity OPtical Coherent Receivers
Data rates of fiber-optic communication systems have been moved beyond 100 Gb/s due to the concerted employment of polarization-division multiplexing (PDM) and advanced modulation formats, assisted by advanced digital signal processing (DSP) techniques.


DSP enabled optical detection

Advanced DSP
The use of higher-order modulation formats, along with higher data rates, requires the employment of more complex and more computationally demanding DSP stages. Moreover, DSP eliminates the need for complex and costly compensation techniques applied in the optical domain.
