Abstract(in English) As digital coherent technologies have matured, a spectral efficiency achieved by the advanced modulation format of optical signals is approaching the Shannon-limit. It is promising to expand the optical bandwidth used for wavelength division multiplexing (WDM) to increase the capacity of optical transmission systems. In this paper, we report on an experiment of wide-band WDM transmission using optical parametric amplifier (OPA)-based inline repeater consists of a periodically poled LiNbO3 (PPLN) waveguide. The OPA-based inline repeater has an amplification bandwidth of 14.1 THz, which exceeds the Raman shift frequency of single-mode fiber (SMF) and can compensate for the span loss of 80 km of SMF. 132 Gbaud PCS-QAM signal is used as a test signal, and the WDM signal with a channel spacing of 137.5 GHz from the S band to the L band is measured. The capacity of 70.4 Tb/s at 400 km and 93.4 Tb/s at 160 km were achieved.
