Metro Network is a telecommunications network that spans a metropolitan area, connecting access networks to core or long-haul infrastructure. It aggregates traffic from enterprises, data centers, and residential users, using high-capacity optical and packet-based technologies to support reliable, low-latency communication. Metro networks enable services such as broadband internet, mobile backhaul, and cloud connectivity, and are designed for scalability, resilience, and efficient traffic management within urban regions.
We report the first field study of the phase and polarization dynamics of deployed antiresonant hollow core fiber cable in a data center interconnect for real-world vibration sensing,revealing enhanced phase sensitivity and significantly faster polarization angular rate compared with standard single mode fibers.
