Ohta, T. Nishio, R. Kudo, K. Takahashi, and H. Nagata IEEE Transactions on Vehicular Technology, Vol. 74, No. 3, pp. 5270–5275, March 2025. This paper demonstrates the feasibility of the real-to-sim-to-real (Real2Sim2Real) scheme for point cloud-based proactive millimeter-wave (mmWave) link quality prediction. To alleviate the mmWave line-of-sight blockage problem, proactive wireless network management based on predicted future link quality values leveraging computer vision-aided deep learning (DL) is an effective solution. However, a large dataset is required to train the high-accuracy DL-based prediction model. In this paper, we configure a Real2Sim2Real pipeline, which aims to automatically generate a realistic synthetic dataset, close to that obtained from real sensors, for pre-training by analyzing a small real-world dataset and computer simulation. Experimental results reveal that our method can reduce prediction errors even with a small sample of real-world datasets for fine-tuning compared with previous pre-training methods using manually created 3D simulation models. Experimental Evaluation of an SDN Controller for Open Optical-circuit-switched NetworksK. Anazawa, T. Inoue, T. Mano, H. Ou, H. Ujikawa, D. Briantcev, S. B. Ali, D. Dass, H. Nishizawa, Y. Sone, E.

Open optical networks have been considered to be important for cost-effectively building and operating networks. Recently, optical-circuit-switches (OCSes) have attracted industry and academia because of their cost efficiency and higher capacity than traditional electrical packet switches and reconfigurable optical add-drop multiplexers (ROADMs). Though the open interfaces and control planes for traditional ROADMs and transponders have been defined by several standard-defining organizations, those of OCSes have not. Considering that several OCSes have already been installed in production datacenter networks and several OCS products are on the market, bringing openness and interoperability into OCS-based networks has become important. Motivated by this fact, this paper investigates a software-defined networking controller for open optical-circuit-switched networks. To this end, we identified the use cases of OCSes and derived the controller requirements for supporting them.We then proposed a multi-vendor (MV) OCS controller framework that satisfies the derived requirements; it was designed to quickly and consistently operate fiber paths upon receiving the operation requests. We validated our controller by implementing it and evaluating its performance on actual MV-OCS networks. It satisfied all the requirements, and fiber paths could be configured within 1.0 s by using our controller. Low-noise Forward Pumping with Optimized Longitudinal Modes for Distributed Raman Amplifier in S+C+L-band TransmissionH. Kawakami, F. Hamaoka, K. Kimura, M. Nakamura, T. Sasai, T. Kobayashi, Y. Miyamoto, and E. Yamazaki The 30th OptoElectronics and Communications Conference/International Conference on Photonics in Switching and Computing (OECC/PSC 2025), TuB2-4, Sapporo, Hokkaido, Japan, June/July 2025. We show the improvement of signal quality in S+C+L-band transmission using a low-beat-noise forward pumping. After 1200-km transmission, the measured signal-to-noise ratios were improved by more than 0.7 dB compared to using a conventional technique. |
