Subsea watertight cable assembly with molded connectors

Subsea Watertight Cable Assemblies

Vulcanized to cable · up to 70 MPa · single, double and multi-ended

We vulcanize our watertight connectors directly to underwater cable, so the connector and cable form one sealed unit. The same process repairs damaged cable and seals branch joints. Assemblies are single-ended, double-ended or multi-branch, with standard, load-bearing, fiber-optic or hybrid cable.

Frequently asked questions

What do you need to quote a subsea cable assembly?

Connector series at each end, cable type and diameter, length, branch layout, pin-out, water depth and any load-bearing or fiber requirements.

Can you repair a damaged underwater cable?

Yes. The same vulcanizing process can repair damaged cable jackets and seal branch joints.
