	abstract = {Remote power supply technology is critical for the long-term, wide-area, and real-time monitoring of marine data in cabled underwater information networks (CUINs). In this study, the constant-current remote power supply system (CCRPSS) of mesh-type CUINs based on constant-current branch equipment (CCBE) and constant-current/constant-voltage conversion equipment (CCVE) is studied. The system can be categorized into various power supply links and link segments according to the current flow path and structural characteristics. A system basic simulation model is designed to analyze the influence of 11 typical faults on the working state of the system and to summarize the influence of the open-circuit/short-circuit faults of various underwater units in different power supply link segments on the working state of the system. Then the analysis method of power supply reliability (PSR) of the observation equipment (OE) is proposed. The PSR of the OE of the same power supply link (PSL) decreases gradually from shore to sea, and the PSR of the OE located at the center of the PSL is the lowest in the regular deployment of the CCRPSS. To increase the number of nodes deployed and to reduce the total cost, an engineering design method for the system that integrates the constraints of the PSR of the OE, the fault rate of the underwater unit, and the number of second nodes of each power supply link segment (PSLS) is proposed based on invasive weed optimization (IWO). Through the example simulation, the results of the system cost, the deployment number of secondary nodes, and the reliability of the underwater units are obtained, which also confirms that the PSR of the OE located at the center of the PSL is the lowest. This method can be effectively applied to the engineering design of CCRPSS and can provide theoretical and technical support for future large-scale CUINs construction.},

	abstract = {Cabled ocean observatories (COOs) have enabled real-time in situ ocean observations for decades, thereby facilitating oceanic understanding and exploration. This review discusses typical COOs worldwide in terms of system configurations and state-of-the-art technology, including network structures, power supply modes, and communication capabilities, and provides a comprehensive analysis of their technical routes. The main characteristics of line, ring, star, and grid networks and their applicability in COOs are elucidated, and the advantages and disadvantages of various power supply modes, as well as the opportunities brought by the development of communication technologies, are described. The insights gained from these discussions can inform the implementation of grid structures, optimization of cable routings, expansion of COO scales, application of dual-conductor submarine cables, and upgrading of communication capacity. On this basis, the challenges and future research directions related to COOs are presented.},
