Product Introduction
Deep-Sea Watertight Optical & Electrical Connectors
1. Product Overview
This series of full-ocean-depth watertight interconnect connectors is a domestically developed high-performance solution for extreme deep-sea environments, independently designed and manufactured for power supply, high-speed data, optical signal hybrid transmission underwater.
The product portfolio covers three core product lines: all-titanium metal heavy-duty photoelectric connectors, rubber wet-mate subsea connectors, and integrated slipring assemblies. The full system passed real sea trial verification at 10,909m Mariana Trench and obtained DNV marine certification, fully replacing imported subsea connector brands.
We provide one-stop subsea interconnection solutions including connectors, custom subsea cables, pressure-resistant housings, winch accessories and optical repeaters, widely adopted in manned submersibles, work-class ROV/AUV, offshore wind, offshore oil & gas, deep-sea observation networks and marine scientific research projects.
Full Product Lineup
All-Sea-Depth Metal Photoelectric Connectors (Dry-Mate, Titanium Alloy)
Rubber Wet-Mate Underwater Connectors (Direct underwater plug/unplug)
Subsea Optical-Electric Slipring Assemblies (Rotary signal transmission)
Custom integrated cable assembly sets
Bulkhead penetrators, flanged & threaded socket accessories
2. Core Competitive Advantages
Verified Full-Ocean-Depth Reliability (11,000m Max)
Titanium alloy housing with double O-ring self-pressure compensation sealing system, withstand up to 110MPa ultra-high hydrostatic pressure. Successfully equipped on full-ocean-depth manned submersibles with dozens of 10,000+ meter sea trial records, stable signal transmission under hadal zone extreme conditions.
Dual Wet & Dry Mate Technical Capability
Two mature technical routes available:
Metal heavy-duty series: high-reliability dry-mate for manned submersibles & offshore platforms
Rubber molded series: support direct underwater wet mating over 500 cycles, convenient field maintenance without equipment recovery.
Flexible Hybrid Signal Customization
Freely combine power contacts, single-mode optical fibers, Ethernet, coaxial radio frequency pins in one connector. Support 1Gbps / 10Gbps high-speed data transmission, low optical insertion loss ≤0.5dB, stable long-distance underwater communication.
Superior Corrosion & Shock Resistance
Optional TA2 titanium alloy / 316L stainless steel housing, resistant to high-salt seawater, thermal fluid and chemical corrosion. Pass 10–2000Hz vibration & 100g impact testing, adapt to rough seabed collision and ocean current vibration scenarios.
Import Interchangeable & Cost-Effective
Rubber wet-mate series fully compatible with mainstream international connector dimensional standards, direct replacement of overseas products with 40–60% cost reduction, short delivery lead time for global export orders.
Complete System Supporting Capacity
Not only single connectors, but full matched subsea transmission kits including customized watertight cables, pressure balancing units, cable strain relief and mounting accessories, simplify customer system integration work.
