In the temperature sensing fiber optic wiring of cable trenches and cable corridors, it is necessary to avoid external damage to the temperature sensing fiber optic, ensure that the fiber optic is intact and undamaged, and ensure that the fiber optic can accurately. Fiber optic sensor cables are the key enabler for real-time monitoring of temperature, strain, and acoustic signals across diverse and challenging environments. Depending on the application and the used technology standard fiber optic telecom cables are suitable, while other applications may. The status of an optic–electric composite high-voltage submarine cable (referred to as submarine cable) can be monitored based on optical fiber-distributed sensing technology, and at the same time, no additional sensor is needed in the monitoring system.
