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, ROV, or underwater housing connects through a waterproof Ethernet bulkhead connector to an external subsea Ethernet cable, which then links to a laptop, switch, router, PoE 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

DNC-1101 - Universal Underwater Ethernet Cable
General-purpose waterproof LAN cable for a wide range of underwater networking applications including subsea cameras, aquariums, inspection systems, and custom underwater monitoring projects.
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, ROV electronics, 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 100ft, 300ft, short patch cables, or custom lengths depending on deployment distance
- Application: camera, ROV, inspection, research, aquarium, 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 waterproof cable 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, live viewing, and remote camera control setups.
Do these cables support Gigabit Ethernet?
Yes. Selected models support Gigabit Ethernet up to 1 Gbps.
Can one cable carry power and data?
Yes, in PoE-compatible systems. Models such as DNC-1020 and DNC-1044 can be used in PoE / PoE+ / PoE++ system designs with compatible equipment.
Do I need a bulkhead connector?
Yes, if the Ethernet line passes through a waterproof housing or pressure enclosure. Dive And See underwater Ethernet bulkhead connectors provide the sealed transition point between the internal device and the external underwater cable.
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.
Need a Custom Solution?
