Fibre Optic + Power Hybrid Cable with Kevlar Reinforcement

This advanced subsea hybrid cable combines fibre optic elements (single-mode or multimode) with copper power conductors and a Kevlar aramid braid for tensile reinforcement, all enclosed in a PUR outer jacket. Purpose-built for ROV tether applications requiring high-bandwidth fibre optic data (HD video, Gigabit Ethernet, acoustic telemetry) alongside power delivery at depth -- with the tensile strength to support the cable's own weight and the ROV/payload mass.

Key Applications

• ROV fibre optic tether cables
• Deep-sea vehicle high-bandwidth data links
• Subsea HD and 4K video transmission
• Ocean floor observatory fibre power feeds
• Military ROV and unmanned underwater vehicle (UUV) tethers

Frequently Asked Questions

What bandwidth can fibre optic elements achieve at depth?

Single-mode fibre (G.652D) supports bandwidth limited only by the transceiver, practically achieving 10Gbps+ over several kilometres with no depth-induced attenuation. This enables full-HD, 4K, and even 8K video streaming from deep-sea ROVs.

How is the fibre protected inside the cable?

Each fibre is housed in a tight-buffered or loose-tube construction with gel filling and surrounded by Kevlar yarn. The overall Kevlar braid provides additional crush and tensile protection. The cable passes a minimum bend radius of 20x OD to prevent fibre damage during deployment.
