Long-Reach Coherent WDM PON Employing Self-Polarization-Stabilization Technique
K. Y. Cho,Kazuki Tanaka,T. Sano,S. P. Jung,J. H. Chang,Yuichi Takushima,Akira Agata,Y. Horiuchi,Masatoshi Suzuki,Yun Chur Chung +9 more
TL;DR: In this article, a self-polarization-stabilization technique for the wavelength-division-multiplexed passive optical network implemented with reflective semiconductor optical amplifiers (RSOAs) and self-homodyne coherent receivers is proposed.
Journal ArticleDOI
Effects of Reflection in RSOA-Based WDM PON Utilizing Remodulation Technique
K. Y. Cho,Yong Jik Lee,Hyoungsoon Choi,A. Murakami,Akira Agata,Yuichi Takushima,Yun Chur Chung +6 more
TL;DR: In this paper, the effect of the reflection on the performance of a single-fiber loopback WDM PON with reflective semiconductor optical amplifiers (RSOAs) is investigated.
Proceedings ArticleDOI
A new IQ data compression scheme for front-haul link in Centralized RAN
Shinobu Nanba,Akira Agata +1 more
TL;DR: A new IQ data compression scheme with 1/2 compression ratio is proposed, which can be easily implemented by using both IQ bit width reduction and a common lossless audio compression scheme.
Proceedings ArticleDOI
Next-generation optical access networks for C-RAN
Keiji Tanaka,Akira Agata +1 more
TL;DR: The required specifications to optical fronthaul links for C-RAN are reviewed and key technologies of optical transmissions and a CPRI data compression for next-generation optical access networks are presented.
Journal ArticleDOI
103-Gb/s Long-Reach WDM PON Implemented by Using Directly Modulated RSOAs
TL;DR: A long-reach wavelength-division-multiplexed passive optical network capable of providing 100-Gb/s service to each subscriber, for the first time to the best of the authors' knowledge, is proposed and demonstrated.
