This research aims to enhance vibration sensing in optical interconnects for improved operational maintenance in data centers.
Proposed a joint phase-based and SOP-based sensing scheme in IM-DD systems.
Utilized a power ratio of 10% from tapped communication signals for vibration sensing.
Developed a Michelson interferometer with Faraday rotating mirrors for phase detection.
Demonstrated vibration sensing capability across a frequency range of 200 Hz to 10 kHz.
Achieved only a 0.8 dB received optical power penalty from the integration of the sensing system.

Zhuo et al. (2026) studied this question.
