Fiber Optic Transmission Systems for Drones | 3–30km Anti-Interference Video Link | Sourced via SourcingProChinaProduct OverviewThe Fiber Optic Transmission System is a wired-backup communication solution designed for drones operating in signal-congested or GPS-denied environments, such as dense urban corridors, underground/tunnel infrastructure, or areas with heavy RF interference. Its dual-channel redundancy allows the system to automatically switch from wireless to physical fiber-optic transmission when wireless signal quality drops, maintaining a continuous video and control link.The system consists of three core components: a fiber reel (up to 20km capacity), an air unit mounted on the drone, and a ground unit connected to the operator's RC controller. It supports real-time video transmission from 3 to 30km, positioning it for long-distance infrastructure inspection, perimeter and border monitoring, and disaster-area reconnaissance where wireless links may be unreliable.SourcingProChina is a sourcing agent based in China. We connect overseas buyers directly with the manufacturers producing this system, coordinating sample testing, factory verification, and order fulfillment on your behalf — without the markup or communication gaps of traditional intermediaries.Technical SpecificationsFiber Reel (20km)ParameterSpecificationProduct NameFiber Optic Discharge BoxFiber Diameter0.28mmSheath MaterialResinousOuter Diameter0.28mm ± 0.01Length20kmOptical TypeG657A2Unit Weight80g/kmWorking Temperature(-40~85)℃Tight Packet ColorInvisible TransparentOptical InterfaceFCAir UnitParameterSpecificationPower Supply5.5V~26VBody Size63×37×23mmBody Weight31±2gBus SignalCRSFVideo SignalAnalogGround UnitParameterSpecificationPower Supply5.5V~26VBody Size65×49×45mmBody Weight56.4gFiber Optic InterfaceFCVideo Output PortRCA_8.4RC ProtocolCRSFKey AdvantagesDual-channel redundancy – Automatically switches to physical fiber-optic mode when wireless signal degrades or interference is detected.Extended, stable range – 3 to 30km transmission suited to both short-range site inspection and long-distance corridor monitoring.Lightweight airborne payload – 31±2g air unit minimizes impact on drone flight time and payload capacity.Low-loss optical fiber – G657A2-grade fiber at 0.28mm diameter, rated for durability across repeated deployment cycles.Tangle-free inner-reel feed – Fiber pays out from the spool core, reducing snag risk during in-flight deployment.Plug-and-play integration – Ground unit connects directly to standard RC controllers via CRSF, minimizing setup time.Wide operating temperature range – Rated for -40°C to 85°C, suitable for extreme climate deployment.Application ScenariosLong-range power line, pipeline, and infrastructure inspectionBorder and perimeter security monitoringDisaster-area and post-disaster reconnaissanceGPS-denied or RF-congested environment operations (tunnels, urban canyons, dense industrial sites)Search-and-rescue support in signal-limited terrainAnti-interference video links for critical facility surveillanceFAQQ1: What is the maximum transmission range?The system supports transmission ranges from 3 to 30km depending on fiber reel length and deployment configuration.Q2: How does the anti-interference feature work?The system uses dual-channel redundancy: it operates on wireless transmission by default and automatically switches to the physical fiber-optic link when wireless signal quality drops below threshold, maintaining continuous video and control data.Q3: What video signal does the system support?The air unit transmits an analog video signal to the ground unit over the fiber-optic link; the ground unit outputs via RCA_8.4.Q4: What is the total weight of the system?Air unit: 31±2g. Ground unit: 56.4g. Fiber reel: 80g/km (a 20km reel weighs approximately 1.6kg).Q5: Can the ground unit connect to standard RC controllers?Yes. The ground unit supports plug-and-play connection to standard RC controllers via the CRSF protocol.Q6: What is the fiber optic interface type?Both the fiber reel and ground unit use FC-type optical interfaces.Q7: Can SourcingProChina arrange factory verification before I place an order?Yes. As a China-based sourcing agent, SourcingProChina can coordinate factory audits, sample testing, and quality inspection prior to bulk order confirmation.
