Autor: Yumiko Senoo, Shin Kaneko, Takuya Kanai, Naotaka Shibata, Jun-ichi Kani, Tomoaki Yoshida

Publikováno v: Optical Fiber Communication Conference (OFC) 2022.

We propose a control method for in-service end-to-end optical paths, and experimentally demonstrate the simultaneous restoration of Ethernet, CPRI, and HDMI signals, which is the world’s first operation of protocol-independent control for end-to-en

High-power-budget End-to-end Optical Connection with AMCC Superposition of SOA-integrated EA-DFB Transmitter in All-Photonics Network

Autor: Yasunari Tanaka, Takahiko Shindo, Kazuaki Honda, Kazutaka Hara, Hirotaka Nakamura, Takuya Kanai, Jun-ichi Kani, Kimikazu Sano, Yumiko Senoo, Shin Kaneko, Tomoaki Yoshida, Mingchen Chen

Publikováno v: 26th Optoelectronics and Communications Conference.

We experimentally evaluate the transmission characteristics of AMCC superposition with an SOA-integrated EA-DFB transmitter for the All-Photonics Network. The results demonstrate that direct optical connections with the power budget of 34.6 dB are ac

Real-time Demonstration of Fairness-aware Dynamic Subcarrier Allocation for Adaptive Modulation in Elastic Lambda Aggregation Network

Autor: Ken-Ichi Suzuki, Kota Asaka, Takuya Kanai, Koji Wakayama, Yumiko Senoo, Akihiro Otaka, Jun Sugawa

Publikováno v: OFC

We propose a dynamic subcarrier allocation algorithm based on transmission parameters and traffic conditions. Real-time demonstration confirms that our algorithm can greatly improve fairness of frame loss rate among ONUs compared to fixed subcarrier

Dynamic Wavelength Allocation and Rapid Wavelength Tuning for Load Balancing in λ-tunable WDM/TDM-PON

Autor: Yumiko Senoo, Jun-ichi Kani, Kota Asaka

Publikováno v: OFC

Dynamic load balancing (DLB) among OLT-ports can keep good user experience by preventing heavy users from occupying the bandwidth. To realize DLB, we present a dynamic wavelength allocation algorithm and a rapid wavelength tuning sequence.
