Key Features
Neutral Buoyancy Design
This cable’s buoyant construction keeps it neutrally buoyant in water, preventing undue weight on your ROV or subsea payload and enabling smoother manoeuvrability.
Hybrid Power + Data Structure
Integrates power supply cores with fiber or data pairs to carry both energy and signals in one robust tether, reducing deployment complexity.
Robust Sheathing
Outer jackets are chosen for flexibility, abrasion resistance and seawater tolerance to protect inner elements from mechanical stress and corrosion.
Tailored Configurations
Core combinations, fiber types, gauge sizes and jacket materials can be adjusted according to voltage, payload and environmental needs.

FAQ — Your Questions Answered
Q1: Can this cable be cut to custom lengths?
Yes. We offer custom length production to match your exact deployment distance and tether management plan.
Q2: Is this cable suitable for saltwater environments?
Yes. Materials are selected to resist corrosion and hydrolysis in marine conditions when correctly specified.
Q3: What is neutral buoyancy and why does it matter?
Neutral buoyancy means the cable neither sinks nor floats excessively, reducing drag and enabling smoother underwater movement.
Q4: How do I choose between 2, 3, or 4 cores?
Select based on the number of power lines and signal/fiber channels your equipment requires. Contact our technical team for guidance.
Q5: Are connectors included?
Connector options are available on request and are tailored to your system’s electrical and optical interface standards.
