This hybrid watertight cable is specifically designed for demanding underwater and harsh-environment applications that require simultaneous power delivery, low-voltage signal transmission, and high-bandwidth optical data communication. It integrates two 20 AWG power conductors, one shielded twisted pair (ATS 1*2*28 AWG) for control or sensor signals, and one single-mode fiber (1SMF) into a multi-layer water‑sealed structure. Utilizing high‑performance insulation materials such as PE on the electrical cores and precision‑protected fiber optics, the cable provides radial watertight performance under high hydrostatic pressure. It is ideal for applications including ROVs, subsea observatories, shipboard bulkhead communications, offshore oil platforms, and military systems - where reliable power, signal integrity, and optical data transmission are critical, all within a watertight envelope. By combining robust electrical characteristics with extreme environmental resistance, this cable ensures stable operation even under deep‑sea pressure and long‑term seawater immersion.

Key Features – Integrated Power, Signal & Fiber Optic Design
PE‑insulated power and signal cores offer a wide -40°C to +105°C operating range, negligible moisture absorption, excellent chemical resistance, and inherent flame retardancy. The shielded twisted pair (ATS 1*2*28 AWG) provides superior EMI rejection and reliable low‑voltage signal transmission. The single‑mode fiber (1SMF) enables long‑distance, high‑bandwidth data links with extremely low attenuation. Multi‑layer water‑blocking and pressure‑resistant construction ensures absolute watertight integrity without requiring mechanical tension strength.
Ideal For
Subsea robots (ROVs/AUVs) and underwater cameras requiring simultaneous power, control signaling, and real‑time video/data transmission
Submarine and shipboard Ethernet backbones with watertight bulkhead penetration (complementing fiber‑to‑Ethernet conversion)
Subsea observatories and ocean monitoring networks (cabled seafloor nodes needing hybrid power/fiber links)
Offshore drilling platforms and marine renewable energy systems
Military and defense underwater communication systems
Any underwater application demanding reliable mixed power, signal, and fiber optic transmission + watertight integrity without mechanical tension requirements
This cable simultaneously satisfies underwater equipment needs for robust power delivery, reliable low‑speed signal control, and high‑speed optical data communications under extreme hydrostatic pressure.
It is an ideal solution for fields such as marine engineering, subsea surveillance, oceanographic research, and underwater defense communication.
