Underwater Optical Wireless Communication Systems

Key features

• Optimized for blue-green wavelengths (ideal for low-absorption underwater propagation)
• Modular laser and receiver units for flexible deployment
• Designed for shallow to medium-depth water with variable turbidity
• Supports both line-of-sight and diverging-beam configurations
• Suitable for environmental monitoring, subsea robotics, and research applications

Typical performance

• Operating Wavelength
• 450–530 nm (Blue-Green spectrum)
• Data Rate
• 1–100 Mbps (water clarity & alignment dependent)
• Transmission Range (LoS)
• 1–50 m (typical 5–30 m; up to 50 m in clear water)
• Laser Source
• DPSS or diode-based; safety class per IEC 60825-1 (configuration-dependent)
• Beam Divergence
• 1–5 mrad (configurable for wide/narrow coverage)
• Receiver Sensitivity
• Down to -35 dBm with optical filtering
• FoV (Receiver)
• 10 to 60 (lens-dependent; higher FoV reduces range)
• Environmental Rating
• Submersible, IP68-rated housing (depths up to 50 m)
