High-Power Hybrid Optoelectronic Connector for Deep-Sea is a hybrid opto-electronic watertight connector that combines single-mode fiber channels and electrical power cores in one housing, so a single penetration serves both the data link and the power feed.
Product Highlights
- hybrid in one penetration: the hybrid housing carries configured to order (1F / 2F / 4F and above) and configured to order (1E - 8E) together, replacing separate optical and power feed-throughs.
- Low signal loss: precision-milled ceramic fiber ferrule with ferrule loss ≤2 dB; low insertion loss and high return loss verified by OTDR test.
- Robust power delivery: 5–20 A per core at 300–600 VAC/DC with insulation resistance ≥200 MΩ; gold-plated copper contacts keep contact resistance low.
- Deep-water rated: 10 MPa hydrostatic pressure resistance (approx. 1,000 m seawater) with NBR O-ring sealing and a locking-cap coupling tightened after insertion.
- Built for seawater: 316L stainless steel / titanium alloy / sea-copper shell options resist salt-spray corrosion; special sealing rings maintain long-term watertightness.
- Flexible in the cold: special PUR (polyurethane) tail cable keeps good bending performance at −60 °C and resists oil and radiation.
- Mechanically secure: 50–500 kg cable tensile strength; insert-then-lock coupling prevents loosening under vibration and shock.

Structure & Mating
The plug housing integrates an optical terminal jack module and an electrical terminal jack module with identical outer diameters, mounted through matching holes in the housing. The optical jack module mates with the optical terminal pin module, and the electrical jack module mates with the electrical terminal pin module, so one mating cycle completes both the fiber link and the power connection. After insertion, tighten the locking cap to secure the joint against vibration.
Applications
- Underwater drones (ROV / AUV) — power and data through a single bulkhead penetration
- Underwater cameras and subsea systems with fiber-optic video backhaul
- Railway signal control systems and mining equipment in wet or harsh conditions
- Marine monitoring and offshore sensor installations

FAQ
1. Can I order a different optical/electrical channel combination?
Yes. Standard builds cover single-fiber, 1F2E, 2F2E, 2F4E, 4F2E, 4F4E and larger layouts; other combinations can be configured to order.
2. What depth is this connector rated for?
The standard design withstands 10 MPa hydrostatic pressure, approximately 1,000 m of seawater. Deeper ratings can be engineered on request.
3. Which fiber interfaces does the pigtail support?
LC, SC, FC and other common terminations are available; every optical tail is fitted with a dust cover.
4. What thread and mounting options are available?
7/8-14UNF bulkhead thread is standard; other thread specifications are optional.
5. Can cable length and shell material be customized?
Yes. PUR tail-cable length, 316L / titanium / sea-copper shell material and pin layouts are all customizable.
