Underwater TV Cable with 2 Coaxial Conductors | Dual-Coax Subsea

Underwater TV cable with 2 x 75 ohm coaxial conductors for dual-camera ROV systems. PUR jacket, individually shielded coaxes, subsea rated. Custom lengths available.

Product introduction

Underwater TV Cable with 2 Coaxial Conductors for Dual-Camera ROV Systems

Combining two independent 75-ohm coaxial channels in a single compact PUR-jacketed cable, this underwater TV cable is the ideal solution for ROV systems equipped with dual cameras -- such as a primary forward-looking camera and a secondary manipulator or downward-looking camera. Each coaxial channel is individually shielded, preventing signal interference between video streams.

Key Applications

  • ROV dual-camera tether systems
  • Stereo-camera subsea platforms
  • Pipeline inspection with main and overview cameras
  • Subsea valve and manifold inspection
  • Port security dual-camera installations

Frequently Asked Questions

How does this cable compare to running two separate coax cables?

A single dual-coax cable reduces drag, simplifies cable management, and is easier to deploy and recover. It also reduces the risk of entanglement in subsea environments compared to two separate cable runs.

Can the coaxes carry SD-SDI and HD-SDI simultaneously?

Yes. Each 75-ohm channel independently supports SD-SDI or HD-SDI, so you can transmit different video formats on each channel simultaneously -- useful when mixing legacy and modern camera systems on the same ROV.
