Laser Optical Communications

Laser Optical Communication

At qtlabs, we deliver high-performance C-band laser communication (com) systems for both terrestrial and satellite-based communication. Designed to support high data throughput, low latency, and interference-free operation, our systems are optimized for modern optical and quantum communication architectures.

Standards-Compliant and Interference-Free

Our C-band com solutions are built to comply with:

• CCSDS (Consultative Committee for Space Data Systems)
• SDA (Space Development Agency) standards

Operating within the license-free C-band, our systems deliver robust performance with minimal interference, making them suitable for a wide range of commercial and governmental communication infrastructures.

Key Features

• Wavelength Band: C-band (centered around 1550 nm), ideal for fiber and free-space optical links
• Supported Modes: Rx (Reception) and Tx (Transmission) configurations
• Standard Tx Output Power: 5W, with optional power upgrades available upon request for extended range or link margin improvement
• High Bandwidth & Low Latency: Enables efficient high-speed data transmission, critical for time-sensitive applications

Integration with Quantum Communication Systems

In addition to standalone applications, our C-band Laser com systems play a critical role in quantum infrastructure, including:

• Input for Atmospheric Turbulence Mitigation:
  • Serves as a reference beacon signal for wavefront sensors in adaptive optics systems
• Optical Bench integration at telescope system together with quantum signal

These capabilities make our laser optical com units a cornerstone technology for integrated quantum-classical hybrid systems.
