5120-km RZ-DPSK transmission over G.652 fiber at 10 Gb/s without optical dispersion compensation

Abstract

We report the longest unregenerated reach achieved for a 10-Gb/s return-to-zero differential phase-shift keying system on standard dispersion fiber (G.652) with no optical dispersion compensation. A total of 82.433 ns/nm of chromatic dispersion compensation was achieved.
