As drone applications increasingly move into industrial-grade and high-reliability environments, transmission system design is no longer a competition of bandwidth alone—it has become a competition of physical-layer stability.
Among emerging solutions, single-mode fiber (SMF) video transmission is becoming a critical option in high-interference environments.
Why Anti-Interference Capability Must Be Addressed at the Physical Layer
Traditional wireless video return systems rely on:
- Spectrum allocation
- Transmission power optimization
- Anti-jamming algorithms
These approaches are effective in most scenarios. However, in environments with strong electromagnetic interference (EMI) or spectrum congestion, latency and signal attenuation can still occur.
When mission requirements demand extremely high stability, wireless optimization alone is insufficient.
The transmission medium itself must be reconsidered.
Technical Principles of Single-Mode Fiber
Single-mode fiber features a core diameter of approximately 8–10 μm, allowing optical signals to propagate in a single mode. Compared to multimode fiber, this significantly reduces modal dispersion.
Key advantages include:
- Low attenuation over long distances
- High bandwidth potential
- Immunity to electromagnetic interference
- High signal confidentiality
In drone applications, this translates to:
- Video signals unaffected by external EMI
- Stable transmission of control commands
- Predictable latency performance
Architecture Design of Fiber Optic Video Transmission Modules
Common system configurations include:
- TX1310nm / RX1550nm wavelength separation
- Single-fiber bidirectional (BiDi) architecture
- Industrial-grade FC connector interface
- 100 Mbps transmission rate
- Synchronized CVBS video and TTL control signal transmission
It is important to clarify that the 100 Mbps data rate is not intended for ultra-high-definition video.
Rather, it ensures reliable synchronization of standard video signals and control data.
In specific mission-critical scenarios, stability outweighs resolution performance.
System Integration Considerations
When designing a fiber optic guided drone architecture, the following factors must be evaluated:
- Fiber type and quality (OS1 / OS2)
- Fiber management mechanisms
- Actual mission distance
- Video compression format
- Flight strategy
While the fiber optic module provides the physical-layer foundation, a complete system still requires integration with flight control systems and video processing units.
Compliance and Supply Chain Security
In high-end application markets, technical performance alone is not sufficient.
Supply chain origin and compliance are equally critical.
This module features:
- Manufactured in Taiwan
- Non-PRC supply chain
- TAA Compatible architecture support
- ISO-certified manufacturing processes
These attributes support government procurement projects and international program requirements.
Technology Positioning Summary
Single-mode fiber video transmission is not designed to replace wireless systems.
Instead, it provides a more stable alternative in high-interference environments.
When mission success depends on transmission stability, returning to physical-layer design is often the more effective strategy.
