DNC-2084-L Long-Thread Underwater Ethernet Cat6 Bulkhead Connector for ROVs, Cameras, and Marine Systems
The DNC-2084-L is a professional swivel-style underwater Ethernet Cat6 bulkhead connector with an M16x1 long thread, designed for high-speed underwater data communication in camera housings, ROV systems, inspection equipment, and marine electronics.
This connector supports Cat6 Ethernet up to 1 Gbps and is designed to work with Dive And See underwater Ethernet cable systems, including the DNC-1044 300ft underwater Ethernet Cat6 cable and the DNC-1020 100ft underwater Ethernet Cat6 cable.
The elbow swivel design helps reduce cable stress, improve routing inside compact housings, and make installation cleaner when a straight connector is not ideal.
Key Features
- Underwater Ethernet Cat6 bulkhead connector for professional subsea systems
- M16x1 long-thread body for housings that require deeper thread engagement
- Swivel / elbow-style design for flexible cable positioning
- Cat6 Ethernet performance with data speed up to 1 Gbps
- Compatible with PoE, PoE+, and PoE++ systems when used with the proper cable and equipment
- Water block protection to help isolate the housing from cable-side water ingress
- Depth rating: 160m / 240 PSI
- Assembled in USA
- Compatible with Dive And See DNC-1044 and DNC-1020 underwater Ethernet Cat6 cables
Compatible Underwater Ethernet Cables
The DNC-2084-L is compatible with Dive And See underwater Ethernet Cat6 cables, including:
- DNC-1044 - 300ft underwater Ethernet Cat6 PoE++ cable
- DNC-1020 - 100ft underwater Ethernet Cat6 PoE++ cable
These cable options allow the same connector family to be used for both longer 300ft underwater deployments and shorter, easier-to-handle 100ft underwater Ethernet systems.

Why Use the DNC-2084-L?
The DNC-2084-L is useful when a housing requires a longer M16x1 threaded section and a low-profile elbow cable exit. The swivel-style construction gives the installer more flexibility when routing the Ethernet cable inside or outside the housing, especially in tight underwater camera and ROV builds.
Unlike generic waterproof RJ45 adapters, this connector is designed as part of a professional underwater Ethernet system. It is built for marine use, high-speed Cat6 data, and integration with Dive And See underwater Ethernet cables.
Water Block Protection
The DNC-2084-L includes water block protection to help reduce the risk of water traveling through the cable path into the housing. This is an important feature for underwater camera systems, ROV electronics, and other subsea equipment where connector reliability is critical.
Custom Options
Custom cable lengths, connector configurations, and underwater Ethernet system assemblies are available upon request. Contact Dive And See if your project requires a different cable length, connector style, or complete underwater Ethernet solution.

Frequently Asked Questions
Is the DNC-2084-L compatible with the DNC-1044 cable?
Yes. The DNC-2084-L is compatible with the DNC-1044 300ft underwater Ethernet Cat6 cable .
Is the DNC-2084-L compatible with the DNC-1020 cable?
Yes. The DNC-2084-L is also compatible with the DNC-1020 100ft underwater Ethernet Cat6 cable .
What is the difference between DNC-2084 and DNC-2084-L?
The DNC-2084-L uses an M16x1 long-thread body. It is intended for housings or installations where a longer threaded section is needed. The standard DNC-2084 is better for applications where the standard M16x1 thread length is sufficient.
Can this connector support PoE++?
Yes, the connector can be used in PoE, PoE+, and PoE++ underwater Ethernet systems when paired with compatible Cat6 cable, equipment, and proper installation.
What systems is this connector best for?
The DNC-2084-L is designed for underwater camera housings, ROVs, marine inspection systems, subsea Ethernet devices, and professional underwater live-view or remote-control applications.
