DPSK and P-DPSK are most the robust to nonlinear effects.

We validate its design by transporting 51-Tb/s over 2000-km, at 6.7-bit/s/Hz spectral efficiency.

Introduzione Nell'ambito dei Progetti di Ricerca di Rilevante Interesse Nazionale (PRIN), il Ministero dell'Istruzione, dell'Università e della Ricerca (MIUR) ha finanziato, nel 2003, il progetto WONDER, mirato allo studio e alla dimostrazione di una nuova rete ottica a pacchetto ad elevate capacità per ambiente metropolitano [1]. Il progetto -coordinato dal Politecnico di Torino e a cui partecipano diverse Università Italiane -rappresenta l'evoluzione di un precedente prototipo di rete (RingO) [2], ed è basato su un'architettura a doppio anello fisico in fibra in configurazione folded bus, in cui l'architettura di ogni nodo sfrutta efficacemente la tecnologia ottica disponibile. L'architettura di ogni nodo della rete WONDER prevede l'imp...

Inline dispersion-managed systems show better performance than digitally post ocmpensated systems, and can be further improved by 1dB with digdal mitigation of nonlinear phase distortions.
