The optical fibre temperature of the three-core photoelectric composite submarine cable is measured by BOTDA; and the corresponding relationship between the temperature variation of the optical fibre and the conductor is performed by finite element analysis . The optical fibre temperature of the three-core photoelectric composite submarine cable is measured by BOTDA; and the corresponding relationship between the temperature variation of the optical fibre and the conductor is performed by finite element analysis . 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. Currently, this technology is widely used in.
