Waterproof SDI Cable for Professional Underwater Video Systems
The DNC-1126 is a waterproof 3G-SDI extension cable designed to extend professional video connections between underwater camera systems, waterproof bulkhead connectors, submerged equipment, and compatible Dive And See SDI cable assemblies.
The cable is manufactured with a waterproof male connector on one end and a waterproof female connector on the other. This allows compatible underwater SDI cables and camera systems to be extended without opening the camera housing or replacing the existing bulkhead connection.
Its 75-ohm coaxial construction is designed for professional SDI video transmission, including 3G-SDI signals up to 1080p60, depending on the total cable length, connected equipment, and complete system configuration.
Key Benefits
Male and female waterproof connectors allow compatible underwater SDI cables to be connected and extended.
Designed for 75-ohm SDI video applications, including HD-SDI and 3G-SDI video signals.
Nickel-plated marine-grade brass connector bodies provide a strong and durable underwater connection.
Integrated strain relief helps reduce cable stress near the connector and protects the cable during deployment.
Why the DNC-1126 Is Different
Standard BNC extension cables are not designed for submerged connections. The DNC-1126 uses Dive And See waterproof connectors on both ends, allowing the connection point to remain underwater when correctly connected to compatible Dive And See equipment.
This cable is especially useful when an existing underwater SDI system needs additional cable length, a detachable extension section, or easier field deployment.
- Extends compatible underwater SDI cable assemblies
- Creates a detachable connection between cable sections
- Helps simplify transportation, installation, and cable replacement
- Integrates with compatible Dive And See bulkhead connectors and underwater video systems
Main Features
Waterproof Male and Female Connectors
The cable includes one Dive And See waterproof male connector and one waterproof female connector. The mating connection is designed for underwater use when the connectors are properly assembled, tightened, and connected to compatible Dive And See components.
3G-SDI Video Support
The DNC-1126 is designed for professional SDI video transmission, including:
- 3G-SDI
- HD-SDI
- SD-SDI
- Video resolutions up to 1080p60
Important: Maximum supported video format depends on the total combined cable length, camera output, monitor or recorder input, cable condition, and complete system configuration.
Flexible 6.5 mm Cable
The compact 6.5 mm outside diameter helps make the cable easier to route, store, and deploy than larger underwater video cable assemblies.
Custom Lengths Available
The standard DNC-1126 cable length is 1 meter. Custom cable lengths are available for specific underwater camera, inspection, broadcast, and research applications.
Applications
- Underwater camera systems
- Commercial diving video systems
- Underwater inspection
- ROV and subsea equipment
- Scientific research
- Aquaculture monitoring
- Broadcast and live production
- Marine engineering
- Offshore inspection
- Wet-environment CCTV installations
