The DNC-1034 Long-Range Underwater Fiber-Optic HDMI Cable is a specialized underwater-to-surface video cable for professional HDMI transmission over distances that are impractical for conventional passive copper HDMI cables.
Available in standard and custom lengths up to 100 m (328 ft), the DNC-1034 is designed to carry live HDMI video from an underwater camera housing to a surface monitor, recorder, switcher, capture device, or streaming encoder. The stated supported formats are 4K at 24 fps and 1080p60 when every component in the complete HDMI chain is compatible.
A rare long-distance underwater HDMI solution
DNC-1034 uses active optical HDMI technology to provide live underwater HDMI connections at lengths such as 20 m, 30 m, 45 m, 60 m, and up to 100 m. Exact available lengths and connector configurations must be selected or confirmed when ordering.
Why Fiber-Optic HDMI Is Used for Long Underwater Runs
Long passive copper HDMI cables can experience signal loss and reliability problems as distance increases. The DNC-1034 converts the HDMI signal for transmission through optical fiber, allowing a long underwater cable run while retaining a standard full-size HDMI connection at the surface.
The result is a field-serviceable connection between compatible underwater housings and surface video equipment without requiring a separate external HDMI signal booster or booster power supply in the stated configuration.

Typical Underwater HDMI Workflow
- A compatible camera provides HDMI output inside the underwater housing.
- A compatible Dive And See underwater HDMI bulkhead connector creates the sealed transition through the housing wall.
- The waterproof end of the DNC-1034 connects to the external bulkhead.
- The active optical cable carries the HDMI signal to the surface over the selected distance.
- The full-size HDMI Type-A surface connector connects to a compatible monitor, recorder, switcher, capture card, streaming encoder, television, or display.
- The complete system is tested at the required resolution and frame rate before underwater deployment.
Required Dive And See HDMI Bulkhead Connector
Important: The DNC-1034 waterproof connector is designed to mate with Dive And See underwater HDMI bulkhead connectors only. It is not intended to connect directly to underwater bulkhead or waterproof connector systems made by other manufacturers. The selected Dive And See bulkhead must match the housing port, thread, internal camera connector, waterproof interface, and wiring configuration.
DNC-1034 may be used with Dive And See HDMI bulkhead connector models that match the required mechanical and electrical configuration. Browse compatible Dive And See HDMI bulkhead connectors or contact Dive And See with your camera and housing model before ordering.
4K24 and 1080p60 Signal Compatibility
The stated maximum formats are 4K at 24 fps and 1080p60. Successful transmission depends on the complete signal chain, including the camera output, internal HDMI cable, bulkhead connector, DNC-1034 configuration, surface display or recorder, EDID/HDCP behavior, color format, bit depth, and device settings.
Many standard Dive And See HDMI bulkhead systems can be used for 1080p60. A 4K24 workflow requires a bulkhead connector and internal HDMI assembly specifically approved for the required 4K signal. Compatible examples may include DNC-2095, DNC-2128, DNC-2053, DNC-2060, and DNC-2088, depending on housing, connector type, camera, and system configuration.
The maximum resolution and frame rate are determined by the complete HDMI signal path, not by the DNC-1034 cable alone. The system can operate only at the highest format supported by every component. If the selected bulkhead connector or its internal HDMI cable is rated for 1080p60, the complete system should be treated as a 1080p60 system even when the DNC-1034 cable itself supports 4K24. A verified 4K24 bulkhead and internal HDMI assembly are required for a 4K24 workflow.
4K compatibility notice: A cable labeled for 4K does not guarantee that every camera, housing bulkhead, internal HDMI lead, monitor, recorder, or capture device will pass 4K. Confirm and test the complete system before deployment.
Directional Active Optical HDMI
Active optical HDMI assemblies are directional. Connect the underwater source end to the camera or camera housing and the surface display end to the monitor, recorder, switcher, or capture system according to the product markings. Reversing the direction can prevent video transmission.

Compatible Camera Housings and Surface Equipment
DNC-1034 is compatible with Dive And See underwater HDMI bulkhead connector systems when the bulkhead model, waterproof interface, wiring, housing port, and internal HDMI connection match the application. It is not directly compatible with third-party underwater bulkhead connector systems. Dive And See offers bulkhead configurations for selected Nauticam and other professional underwater housings. One current application is the DNC-S4 Sony RX0 II underwater 4K HDMI live-view system , which uses a detachable DNC-1034 optical HDMI cable.
Surface equipment may include HDMI monitors, televisions, Atomos monitor/ recorders, video switchers, capture cards, streaming encoders, and other compatible HDMI devices. The Atomos Ninja V is surface monitoring and recording equipment; it is not the underwater camera source.

Frequently Asked Questions
Why not use a standard copper HDMI cable?
Conventional passive copper HDMI becomes increasingly difficult to use reliably over long distances. DNC-1034 uses active optical transmission for specialized underwater runs up to 100 m.
Is the cable available in 20 m, 30 m, and 100 m lengths?
Standard and custom lengths may include 20 m, 30 m, 45 m, 60 m, and 100 m, as well as other project-specific lengths. Confirm the current selectable options and lead time before ordering.
Does DNC-1034 support 4K60?
This product page specifies support up to 4K at 24 fps and 1080p60. Do not order it for a required 4K60 workflow unless Dive And See confirms the complete cable and bulkhead configuration for that exact format.
Can it be connected directly to a surface monitor?
Yes. The surface end uses a full-size HDMI Type-A connector for compatible monitors, recorders, switchers, capture devices, and displays.
Does the cable require external power?
The stated DNC-1034 configuration does not require a separate inline booster or external booster power supply. The HDMI source and receiving equipment must still provide their normal operating power and compatible HDMI interface.
Can the cable be installed in either direction?
No. Active optical HDMI is directional. Install the underwater source end at the camera housing and the surface display end at the monitor, recorder, switcher, or capture equipment according to the markings.
Which bulkhead connector should I use?
Use a compatible Dive And See HDMI bulkhead connector. The correct model depends on the housing port and thread, camera HDMI connector, internal clearance, required resolution and frame rate, and waterproof connector configuration. The bulkhead and internal HDMI assembly must be verified for the required signal format. View the Dive And See HDMI bulkhead connector collection or contact Dive And See with the full equipment list before ordering.
Where can I find other underwater HDMI cables?
Compare shorter, extension, male-to-female, and other configurations in the Dive And See underwater HDMI cable collection.
Important Handling and Installation Notes
- Confirm the required cable length, connector configuration, HDMI format, and signal direction before ordering.
- Protect the optical cable from sharp bends, crushing, kinking, twisting, and impact.
- Do not exceed the specified minimum bend radius or pulling limit.
- Do not lift underwater equipment by the HDMI cable.
- Keep waterproof connector contacts and sealing surfaces clean and protected.
- Fully tighten waterproof coupling nuts by hand according to the connector instructions.
- Provide strain relief at the underwater housing and surface station.
- Test the complete HDMI chain at the required resolution and frame rate before submerging the system.
