Deep-Sea Cable Connectors – Female Socket & Male Plug
Modular in-line connectors designed to terminate underwater cables with sealed male or female plug ends. These connectors allow the Deep-Sea Underwater Cable to form reliable, removable connections between subsea devices.
Deep-Sea Cable Connectors – M10 Bulkhead
Panel-mount connector that allows the cable to interface directly with enclosures or end-caps. Requires a matching male plug from the Deep-Sea Cable Connectors line to complete a watertight connection.
Deep-Sea Cable Connectors – Dummy Sealing Cap
Used to seal and protect unused connector ends when not in operation. Prevents moisture ingress and maintains system waterproofing in storage, transit, or standby conditions.

This cable is fully compatible with the Subsea M10 Coupling Tube, which allows two lengths of cable to be joined securely using penetrators and potting compound, or enables repositioning of penetrator-mounted components such as lights, switches, or sensors to more accessible locations.

How to waterproof the cable ends?
Waterproofing methods depend on specific requirements, considering factors such as whether it is detachable, waterproof depth, lifespan requirements, environmental conditions, and connection methods (line-to-line, watertight enclosure outlet), etc.
- Simple Waterproofing Treatment: Use cable penetrator, resin potting, etc.
- Waterproofing Treatment within 1000 meters depth: Traditional encapsulation materials sealing, such as gel beads, gland heads used in pump cables, etc.
- Deepwater Waterproofing Treatment: Sealing with vulcanized rubber, pressing waterproof connectors, fixed joints made of polyurethane, etc.
What is the minimum order quantity?
The minimum order quantity is 1 meter, and prices decrease with larger quantities. Please contact us for bulk discount on large order volumes.
How to strip the cables?
Cable stripping can be done using diagonal pliers or a knife blade. Stripping tools or pneumatic/electric wire strippers are used for batch cutting. Kevlar inside may require separate cutting.
What happens if the bending radius exceeds the minimum bending radius?
There is a risk of cable jacket rupture with prolonged excessive bending, and prolonged exposure to ultraviolet radiation should also be avoided.
What is the operating temperature range?
The long-term operating temperature is -20°C to 80°C, and the storage temperature is -20°C to 50°C.
Can it be used if the cable jacket is damaged?
A damaged cable jacket may lead to short circuits or open circuits and can affect waterproofing.
