Industrial drone signal innovation: a complete explanation of FPV fiber transmission technology

1. Why is it worth choosing a fiber-tethered FPV drone?

·Among many industrial-grade drone solutions, fiber-tethered FPV drones are becoming the preferred choice of more and more professional users due to their stability and anti-interference capabilities. Unlike traditional drones that rely on wireless image transmission, it uses a lightweight optical cable to achieve real-time transmission of high-definition video, with almost no delay in the signal transmission process, while avoiding the common signal loss and interference problems of wireless communication.

·This type of drone is particularly suitable for mission environments such as power inspection, tunnel detection, closed space monitoring, military and police reconnaissance, etc., especially in places where radio is prone to failure or wireless signal transmission is not allowed. Fiber optic transmission provides a safer and more reliable alternative.

2.Why are more and more engineering tasks turning to fiber-optic tethered drones?

1️⃣ Signal interference "insulator": obvious advantages in industrial EMI environmentsIn areas close to substations, 5G base stations or large equipment, wireless links are easily interrupted, and signal strength fluctuations can be as high as 70%. Fiber-optic connections are completely isolated from the wireless spectrum, and can stably transmit high-definition video and control commands even in high electromagnetic noise environments.
Typical applications: infrared inspections in refineries and nuclear facility boundary monitoring, both require high-fidelity image transmission in environments without RF exposure.

2️⃣ Double improvement in accuracy and distance: FPV is not just about viewing angles, but controlOur customized G.657.A2 optical fiber can support image signal transmission over 30 kilometers, with sufficient bandwidth and a delay of less than 30 milliseconds, greatly improving the operating experience of remote precision tasks.
Example scenarios: tasks that require extremely high imaging accuracy, such as detecting cracks in wind turbine blades and inspecting insulators on cross-river transmission towers.

3️⃣ Extreme climate "immunity": creating a true all-weather drone system

·The optical cable can still operate normally in an environment of -40°C to 85°C, adapting to climate challenges from plateau snowfields to tropical jungles;

·Using aramid reinforcement, it has a tensile strength of 400~600N and can withstand wind disturbance, entanglement and repeated retraction and release;

·The outer sheath material can be selected from TPU or LSZH, suitable for high humidity and high corrosion industrial sites.
