Micro Hybrid Optoelectronic Connector for Underwater Drones

Description: Micro hybrid optoelectronic connector for underwater drones: single-mode fiber + power in one penetration. 5-20 A, 300-600 VAC/DC, <=2 dB ferrule loss, 10 MPa rated, ceramic ferrule, LC/SC/FC tails.

Product Highlights

  • Optical + electrical in one penetration: a single hybrid housing carries single-mode fiber channels and power cores together. Standard combinations include 1F2E, 2F2E, 4F2E and 4F4E; other channel layouts can be configured to order.
  • 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; 4N oxygen-free copper conductors and 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 that is 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
  • Mining and other harsh industrial interconnection
  • Marine monitoring and offshore sensor installations
