Simultaneous Vibration Sensing and Transmission of a Single-Carrier 5.38 Tb/s Signal Over 41.4 km Weakly Coupled 7-Core Fiber

We demonstrate simultaneous vibration sensing and high-speed communications leveraging a weakly coupled 7-core fiber. Based on DSP-assisted interference fading mitigation, we accurately measure a 100 Hz vibration signal at 41.4 km, while transmitting
