Underwater Communication & Network
Connectors for Underwater Communication and Network Systems
Underwater communication infrastructure -- subsea fiber optic repeaters, acoustic modem networks, seafloor observatory nodes, and offshore communication hubs -- demands connectors that deliver both electrical power and high-bandwidth data with zero in-service failures over multi-year deployments. RV Power Group manufactures subsea Ethernet, hybrid opto-electric, and coaxial connectors designed for subsea communication networks.
Subsea Communication Network Connection Points
| System | Connector Requirement | RV Power Group Series |
|---|---|---|
| Seafloor Observatory Node | High-pin-count Ethernet + power | Ethernet + Hybrid Opto-Electric |
| Acoustic Modem Transducer | Low-loss RF / coaxial | Underwater Coaxial (RF) Series |
| Subsea Fiber Optic Branching Unit | Multi-fiber hybrid connector | Hybrid Opto-Electric Series |
| Underwater WiFi / LTE Gateway | Ethernet + power, compact | Subsea Ethernet Series |
| ROV Tether Termination (high-speed) | GigE + power in single connector | Hybrid Opto-Electric Series |
| Subsea Control / Navigation Computer | Multi-contact power + RS-232/485/CAN | Micro Circular Series |
