Unlike standard heavy underwater cables that pull down ROV bodies and increase propulsion energy consumption, this Fathom ROV floating hybrid cable adopts precision density matching foam extrusion technology to achieve neutral buoyancy underwater. It perfectly matches the lightweight maneuverability design of Fathom observation-class ROVs, greatly reducing vehicle control resistance, avoiding cable tangling around reefs, pipelines and aquaculture facilities, and extending continuous underwater working time of Fathom ROV vehicles.

1. 2 Core Tinned Copper Power Conductors

   Low-resistance oxygen-free tinned copper, 0.5mm²~2.5mm² customizable cross-section, rated 300/500V, stable DC power output for Fathom ROV thrusters, cameras and onboard sensors. Cross-linked PE insulation resists seawater electrolytic corrosion and insulation breakdown under long-term hydrostatic pressure.

2. Single-Mode Fiber Optic Unit

   Embedded single-mode optical fiber bundle, supporting gigabit low-latency data transmission, real-time 4K underwater video, sonar signal, navigation SLAM and remote control command delivery, no signal attenuation within working depth range. Water-blocking gel filled fiber tube prevents seawater penetration to damage optical cores.

3. Central Aramid Kevlar Strength Member

   High-tensile Kevlar fiber reinforcement layer bears all pulling load during ROV deployment, recovery and fast navigation; power and fiber cores stay stress-free, breaking strength customizable from 100kg to 500kg to match different Fathom ROV model tonnage.

4. Zero Buoyancy PUR Foam Outer Jacket

   High-visibility yellow polyurethane foam sheath with balanced density close to seawater (1.03g/cm³), achieves full floating state underwater. Abrasion-resistant, anti-UV, salt-spray resistant, IP68 deep waterproof, withstands repeated winding on cable reels and frequent bending without cracking. Minimum bend radius only 6× cable outer diameter, ultra-flexible for narrow-space underwater inspection.

5. 3. Full Water-Blocking & Deep-Sea Reliability

   Every internal component is wrapped with water-blocking swellable fibers. Once the outer jacket is scratched by seabed rocks, the absorbent material expands instantly to block seawater infiltration, protecting copper power cores and optical fibers from short circuit or signal failure. Suitable for continuous long-hour underwater operation of Fathom ROV inspection missions.

   H3: 4. Ultra-Flexible & Anti-Torsion Construction

   Stranded ultra-fine copper conductors and torque-balanced cable structure support 720° repeated torsion without wire breakage. Perfect for Fathom ROV rotating camera and multi-angle underwater detection, no kinking or wire fatigue after thousands of bending cycles.

   H3: 5. Fully Customizable for All Fathom ROV Models
