Product Description
The Neutrally Buoyant Cable is a high-performance, zero-buoyancy photoelectric composite cable specially engineered for demanding underwater applications. Designed for long-term deployment in freshwater and marine environments, it integrates 9 single-mode optical fibers and 4 power conductors within a single robust cable.
This hybrid design enables simultaneous high-speed optical signal transmission and reliable power delivery, eliminating the need for multiple separate cables. With true neutral buoyancy in freshwater, the cable maintains stable positioning underwater without floating or sinking, significantly reducing mechanical stress on connected equipment and simplifying installation and recovery operations.
Built with premium TPU (Thermoplastic Polyurethane) outer sheath material, the cable offers exceptional resistance to abrasion, hydrolysis, seawater corrosion, and high hydrostatic pressure, making it ideal for prolonged submersion in challenging subsea conditions.
