FAQ
Q1: Can the buoyancy be adjusted for different water depths?
Yes. Buoyancy can be fine-tuned based on water type (freshwater or seawater) and deployment depth.
Q2: Is this cable suitable for dynamic ROV operations?
Absolutely. The structure is designed to handle continuous motion and repeated bending cycles.
Q3: Can power and data be combined in one cable?
Yes. Hybrid designs combining power, control, and communication cores are available.
Q4: What is the typical service life underwater?
Service life depends on application conditions, but the materials are selected for long-term submerged operation.
