title: 160 Gbit/s-300 km single-channel transmission in the 1.1 μm band with a precise GVD and slope compensation.
abstract: We report a 160 Gbit/s single-channel OTDM transmission in the 1.1 μm band using a high-Δ single-mode step-index fiber (SIF) and ytterbium-doped fiber amplifiers (YDFAs). The 160 Gbit/s OTDM signal was generated from a 10 GHz mode-locked Yb fiber laser. The dispersion and dispersion slope of the SIF were precisely compensated with a chirped fiber Bragg grating (FBG) and a pre-chirping technique, respectively. A nonlinear optical loop mirror (NOLM) was employed to demultiplex the 160 Gbit/s OTDM signal to 10 Gbit/s. As a result, we achieved a 100 km transmission with a BER of < 10⁻⁹ and a 300 km transmission with a BER of < 10⁻³, which is below the standard FEC limit at a net bit rate of 149.5 Gbit/s taking the 7% FEC overhead into account.
