Aoft Technology FPV Fiber Optic Module v4.1 — Waterproof, 0.35mm, 1–20KM, Anti-Interference UAV Video & Data Link

The Aoft Technology FPV Fiber Optic Module v4.1 is a professional fiber optic video and data transmission system for UAV and FPV platforms that demand zero electromagnetic interference, ultra-long-range tethered operation, and high-definition video transmission in RF-denied or electromagnetically complex environments. Using 0.35mm diameter G657A2 fiber optic cable as the transmission medium, the v4.1 module provides fast, high-bandwidth data transfer immune to radio jamming, eavesdropping, and terrain obstruction. The Waterproof Transparent Version 4.0 design features a fully transparent outer barrel and inner shaft for easy maintenance, self-developed black-coated fiber for sun absorption and reduced reflection, and water, wear, and bend resistance for field, forest, desert, and water surface deployment. Available in sky-end cable lengths from 1KM to 20KM. Ground end unit must be purchased separately.

Key Features

Zero EMI / Anti-Interference — Fiber optic transmission is completely immune to electromagnetic interference, radio jamming, and signal theft; operates reliably in contested RF environments, GPS-denied areas, and complex industrial electromagnetic settings where RF links fail
Ultra-Long Range — Up to 30KM Max Payout — High-speed, high-bandwidth fiber supports cable payout up to 30KM; available sky-end spools from 1KM to 20KM for mission-specific range requirements
0.35mm Ultra-Fine G657A2 Fiber — Industry-standard G657A2 bend-insensitive single-mode fiber at just 0.35mm diameter; ignores terrain obstruction and fits through confined spaces; tension rated >50N
Waterproof Transparent v4.0 Design — Transparent ABS outer barrel and inner shaft for easy daily inspection and maintenance; self-developed black-coated fiber absorbs sunlight to eliminate reflection and improve concealment; water-resistant, wear-resistant, bend-resistant; suitable for water surface operations
High-Definition Video & Data — Fiber optic medium supports high-bandwidth HD video transmission and real-time data with fast, stable throughput; no compression artifacts from RF congestion
Tethered UAV & Confined Space Operations — Ideal for tethered UAV platforms entering enclosed or GPS-denied spaces; provides real-time HD imagery and telemetry without relying on RF penetration
Aluminum Alloy Outlet Nozzle — Durable aluminum alloy fiber outlet nozzle on all variants; protects the fiber exit point during deployment and retrieval

⚠️ Important: Sky End vs. Ground End

All variants listed here are Sky End (drone-mounted) units only. The sky end must be used together with the ground end. The ground end is NOT included and must be purchased separately. Select the “Ground Plus” variant to purchase the ground end unit only.

Frequently Asked Questions

Choose the receiver protocol matching your radio transmitter:
