Twisted Pair Underwater Neutral Buoyancy Umbilical Power Fiber Hybrid Cable ROV Tether Cable

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Hybrid Power & Data Transmission: Combines low-voltage power delivery with fiber-optic data capabilities, enabling simultaneous energy supply and high-speed communication for underwater ROV (Remotely Operated Vehicle) systems.
  • Neutral Buoyancy Design: Maintains stable positioning in water due to balanced density, reducing strain on deployment systems and ensuring consistent operational performance.
  • Twisted Pair & Shielded Construction: Twisted copper conductors minimize electromagnetic interference (EMI), while foil shielding enhances signal integrity for critical applications.

Key features

  • 1. Material Technology

    • With copper conductors and PE (polyethylene) insulation, ensure reliable power and data transmission in harsh underwater environments. The stranded and braided copper design enhances flexibility and durability, while the neutral buoyancy material maintains structural integrity without adding drag.

  • 2. Scenario Solutions

    • With a neutral buoyancy design, maintain stable positioning during underwater missions without adding drag to ROVs (Remotely Operated Vehicles). This makes the cable ideal for long-term deployments in marine exploration, subsea robotics, and offshore operations.

  • 3. Performance Parameters

    • With a hybrid power/fiber architecture, support simultaneous high-power delivery and high-speed data transmission. The twisted pair configuration minimizes signal interference, ensuring optimal performance for ROV tether applications.

  • 4. Material Technology (Shielding)

    • With foil shielding and braided conductor layers, reduce electromagnetic interference (EMI) and radio frequency interference (RFI). This protects critical data and power signals in electrically noisy environments.

  • 5. Certification Standards

    • Designed to meet marine industry standards for underwater applications.*

Supplier's note

  1. Technical Breakthroughs:

    • Neutral Buoyancy: Achieved via specialized PE foam cores, reducing ROV operational drag by 25% compared to standard cables.
    • Hybrid Integration: Combines power and fiber optics in a single cable, cutting deployment time by 30% versus dual-cable systems.
    • Enhanced Shielding: Foil + braided layers block 99% of EMI, outperforming industry standards by 20dB.

  2. Version Selection Guidance:

    • Base Model: Ideal for standard ROV operations (e.g., shallow-water surveys) requiring basic power/data needs.
    • Advanced Model: Suited for harsh environments (e.g., offshore drilling) with higher temperature demands and moderate data speeds.
    • Pro Model: Designed for deep-sea exploration or high-speed data applications (e.g., real-time 4K video streaming), with triple the EMI resistance of industry benchmarks. Pair its 10 Gbps speed with submersible cameras to enable seamless HD transmission.

*Pro Model buoyancy exceeds industry standards by 20%.
