Product Introduction

PDK81601-4×2×26AWG以太网浮力系缆(4对26AWG裸铜、PE绝缘、发泡PUR护套、可支持PoE供电、外径7.8mm)

面向ROV/AUV、海底传感器、海洋机器人与水下通信系统设计的中性浮力以太网系缆,支持高速数据传输并可选配以太网供电(PoE)。4×2对26AWG裸铜线芯,PE绝缘;采用发泡PUR构造使整缆密度匹配海水,在水中零净浮力悬浮,消除拖曳与钩挂隐患,降低系缆张力和疲劳,提升载具机动性、定位保持能力与作业航程,尤其适用于海流或深水布放场景。耐水压5MPa,耐温-40~105℃,适合观测级/迷你ROV、水下无人机等零阻力系缆应用。

This product is a high-performance neutrally buoyant Ethernet tether cable specifically designed for underwater Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs), subsea sensors, marine robotics, and underwater communication systems. It integrates reliable high-speed data transmission with optional Power over Ethernet (PoE) capability, while maintaining precise neutral buoyancy in seawater and outstanding flexibility, corrosion resistance, and mechanical durability.

Unlike standard underwater cables that sink to the seabed and create drag, snagging, or entanglement hazards, this cable is engineered to remain suspended in the water column with zero net buoyancy. By matching its overall density to that of seawater through a specialized foam polyurethane (PUR) construction, the cable eliminates hydrodynamic lift or drag on the vehicle, significantly improving maneuverability, station-keeping performance, and operational range, especially in currents or deep-water deployments. The design reduces tether tension and cable fatigue, extending both the cable's lifespan and the underwater vehicle's effective mission duration.

Ideal for:

Observation-class ROVs, mini-ROVs, and underwater drones requiring zero-drag tether

AUVs and marine robotics for subsea inspection, mapping, and surveillance

Underwater camera systems and live video streaming (supports Gigabit Ethernet and PoE)

Subsea sensor arrays, data acquisition systems, and oceanographic monitoring stations

Sonar systems and towed arrays requiring precise depth alignment and vibration damping

Shallow‑water monitoring, aquarium systems, and swimming pool cleaning robots

Military and defense applications (mine detection, naval surveillance, harbor security)

Marine research and exploration equipment, hydrographic survey systems

This cable simultaneously meets the demanding requirements of underwater equipment for high‑speed data transmission, real‑time video, sensor telemetry, and control signals, while the neutral buoyancy design eliminates the need for additional flotation devices or complex tether management systems. The lightweight, flexible construction reduces drag on the vehicle, prevents snagging on seabed obstacles, and ensures smooth deployment and retrieval from winch systems.
