RG58 50 ohm coaxial cable with Vectran braid (1200 kg breaking strength) and PUR jacket. High tensile, deep-sea rated for ROV and subsea data link applications.
This high-performance underwater coaxial cable combines an RG58 50-ohm coaxial core with a Vectran high-modulus fibre braid providing 1,200 kg breaking strength, enclosed in a PUR outer sheath. Vectran outperforms Kevlar in flex fatigue and creep resistance, making this cable exceptional for dynamic deep-sea tether and winch applications where the cable must withstand repeated bending and high tensile loads without performance degradation.

Vectran offers superior flex fatigue life and near-zero creep under sustained tension compared to Kevlar. In dynamic tether applications where the cable repeatedly bends over a sheave or drum, Vectran maintains its breaking strength far longer than Kevlar, reducing the risk of sudden tensile failure.
RG58 50-ohm cable is used for RF signals (sonar, acoustic), Ethernet over coax (MoCA), RS-485, and general RF communications up to several GHz. It is a standard in subsea acoustic systems and can carry digital data at frequencies up to 1 GHz or more depending on the run length.
