High-Capacity Transmission refers to the ability to transmit large amounts of data, typically over communication channels such as optical fibers, wireless networks, or other transmission mediums. In the context of telecommunications and networking it describes systems that can handle significant volumes of data traffic, allowing for faster and more efficient communication. High-capacity transmission is crucial for meeting the growing demand for data-intensive applications, including video streaming, cloud computing, virtual reality, and the Internet of Things (IoT). Advances in communication technologies continue to push the boundaries of capacity, allowing for more efficient and faster transmission of information across various mediums.

First Field Trial of Distributed Fiber Optical Sensing and High-Speed Communication Over an Operational Telecom Network

/in /by

To the best of our knowledge, we present the first field trial of distributed fiber optical sensing (DFOS) and high-speed communication, comprising a coexisting system, over an operation telecom network. Using probabilistic-shaped (PS) DP-144QAM, a 36.8 Tb/s with an 8.28-b/s/Hz spectral efficiency (SE) (48-Gbaud channels, 50-GHz channel spacing) was achieved. Employing DFOS technology, road traffic, i.e., vehicle speed and vehicle density, were sensed with 98.5% and 94.5% accuracies, respectively, as compared to video analytics. Additionally, road conditions, i.e., roughness level was sensed with >85% accuracy via a machine learning based classifier.
