Dive And See underwater Ethernet cables are designed for reliable high-speed data transmission between submerged equipment and surface systems. These waterproof Cat6 and Cat6A Ethernet cable solutions are used in underwater cameras, ROVs, marine research instruments, aquarium monitoring, industrial inspection systems, and custom subsea communication projects.
Selected models support Gigabit Ethernet and Power over Ethernet (PoE / PoE+ / PoE++), allowing both data and electrical power to travel through a single underwater cable in compatible system designs.
Typical underwater Ethernet system connecting a surface control station to an underwater housing or subsea device through a waterproof cable and bulkhead connector.
What Is an Underwater Ethernet Cable?
An underwater Ethernet cable is a waterproof network cable designed to transmit data between subsea devices and surface equipment. In a typical configuration, a camera, sensor, or underwater housing connects through a waterproof Ethernet bulkhead connector to an external subsea Ethernet cable, which then links to a laptop, switch, router, injector, recorder, or control station on the surface.
Typical Underwater Ethernet System
Surface laptop or control station → network switch or PoE injector → underwater Ethernet cable → waterproof bulkhead connector → underwater camera housing, ROV, sensor, or subsea enclosure

Ethernet Cables and Bulkhead Connectors
Underwater Ethernet cables are commonly used together with waterproof Ethernet bulkhead connectors installed in underwater housings or pressure vessels. This creates a sealed transition point between the internal device and the external subsea cable.
- Underwater camera housings
- Pressure vessels and subsea enclosures
- Custom electronics housings
- ROV systems
PoE Underwater Systems
In compatible systems, Power over Ethernet allows both data and electrical power to travel through one underwater cable. This can simplify installation for subsea cameras, IP-based sensors, and remote monitoring equipment.
For higher-power or special-purpose systems, separate Ethernet and regulated DC power lines may still be required depending on device requirements, cable length, and total power draw.
How to Choose the Right Underwater Ethernet Cable
- Length: choose short patch cables or long-distance surface-to-underwater cables
- Application: camera, ROV, inspection, research, or custom subsea electronics
- Shielding: standard Cat6 or shielded Cat6A for noise-sensitive environments
- Power: data-only or PoE-compatible system design
- Connector style: direct connection or cable used through a waterproof bulkhead connector
Frequently Asked Questions
Can these cables be used with underwater cameras?
Yes. They are commonly used for underwater camera systems, remote monitoring, and live viewing setups.
Do these cables support Gigabit Ethernet?
Yes. Selected models support Gigabit Ethernet (1000 Mbps).
Can one cable carry power and data?
Yes, in PoE-compatible systems.
Do I need a bulkhead connector?
Yes, if the Ethernet line passes through a waterproof housing or pressure enclosure.
Are custom lengths available?
Yes. Custom cable lengths and configurations are available for many subsea applications.
Important Tightening Warning
Before submerging any underwater housing or cable assembly, verify that the coupling nut is fully tightened by hand. Do not use pliers. Improper tightening may cause flooding, signal loss, or equipment damage.
