Underwater Hybrid Cable | Power + Signal + Ethernet Subsea Cable

Multi-function underwater hybrid cable combining power, signal, and Ethernet conductors. PUR jacket, compact design for ROV and subsea system integration.

Product introduction

Underwater Hybrid Cable -- Power, Signal, and Ethernet in One

The Underwater Hybrid Cable integrates power conductors, signal pairs, and Ethernet twisted pairs into a single compact cable assembly, enclosed in a durable PUR outer jacket. Designed for next-generation ROV tether and subsea integration applications, this hybrid cable eliminates the need for multiple separate cables, reducing drag, weight, and installation complexity.

Frequently Asked Questions

Can you combine fibre optic with power and signal in one hybrid cable?

Yes. We manufacture hybrid cables combining single-mode or multimode fibre optic elements with copper power and signal conductors. Fibre optic hybrid cables are ideal for high-bandwidth data over long subsea cable runs. Contact us with your fibre count and copper requirements.

What is the typical outer diameter of a hybrid cable?

OD depends on conductor count and armour type, but compact hybrid cables with power + 4 signal pairs + 4 Ethernet pairs typically range from 10--20 mm OD. We optimise OD for minimum drag and maximum flexibility.
