Ultra-Wideband WDM Transmission in S-, C-, and L-Bands Using Signal Power Optimization Scheme
Fukutaro Hamaoka,Masanori Nakamura,Okamoto Seiji,Kyo Minoguchi,Takeo Sasai,Matsushita Asuka,Etsushi Yamazaki,Yoshiaki Kisaka +7 more
TL;DR: In this paper, the authors proposed and demonstrated a scheme to optimize the fiber input powers for UWB transmission systems considering the signal power transition caused by the inter-band stimulated Raman scattering (SRS).
Proceedings ArticleDOI

150.3-Tb/s Ultra-Wideband (S, C, and L Bands) Single-Mode Fibre Transmission over 40-km Using >519Gb/s/A PDM-128QAM Signals
Fukutaro Hamaoka,Kyo Minoguchi,Takeo Sasai,Matsushita Asuka,Masanori Nakamura,Okamoto Seiji,Etsushi Yamazaki,Yoshiaki Kisaka +7 more
TL;DR: A record capacity of 150.3-Tb/s SMF transmission over 40-km is achieved with 13.6- THz ultrawideband WDM 45-GBaud PDM-128QAM signals with spectral efficiency by using the proposed optimization scheme of fibre input powers considering the nonlinear interaction by stimulated Raman scattering.
Journal ArticleDOI
A Study on the Effect of Ultra-Wide Band WDM on Optical Transmission Systems
Okamoto Seiji,Kyo Minoguchi,Fukutaro Hamaoka,Kengo Horikoshi,Matsushita Asuka,Masanori Nakamura,Etsushi Yamazaki,Yoshiaki Kisaka +7 more
TL;DR: In this article, the authors proposed a scheme for allocating wavelength adaptive modulation to exhaustively use wavelength dependent optical signal-to-noise ratio (OSNR) for UWB WDM systems.
