5km Fiber Optic Spool With Aerial Communication Module, Drone Tether Optical Fiber Payload Device

5 KM Fiber Optic Spool for High-Altitude Tethered Drones

Treasure Marine has fiber optic spools of 5 km in length. They are fully compatible with tethered drones for battery-less operations. There will be no more reliance on n batteries when it comes to fiber optic drones. This length is good enough for operations where users do not need much altitude. These fiber optic cables are very lightweight, providing continuous support and high stability. Tethered drones will achieve complete coordination with ground stations through our fiber optic spools.

This 5 km optical fiber spool, matched with an aerial module, is specially designed for a multi-rotor drone platform. It adopts a high-strength, lightweight structure, which can be quickly mounted on the drone as an airborne payload. The built-in optical fiber realizes stable long-distance signal transmission, effectively resisting electromagnetic interference and ensuring a continuous and reliable data link. It supports long-range flight operation up to 5 kilometers. The compact cylindrical housing saves aircraft load space, and the optimized fiber unwinding structure avoids fiber breakage during flight.

Making Operations Jamming-Proof and Uninterrupted

• They help tethered drones fly for hours and even days by providing continuous power from ground stations.

• Making operations safe from every kind of jamming by eliminating all signal EMI. 

• Drones will get safety from hacking systems since there is no involvement of signals in connectivity.

• This is why drones store data at the ground stations only through fiber optic cables.

• These spools release and recoil fiber optic cables as per the drone’s movement.

Long-Hour Coverage without Energy Shortage

Our fiber optic cable spools help organizations cover events that need hours of continuous recording without power interruption. Because tethered drones run without onboard batteries, these spools keep them connected to a steady power and data link for the entire shoot. Whether it is a live sports broadcast, a large public gathering, or a long-duration inspection, the spool delivers reliable performance, stable transmission, and uninterrupted flight time, so your crew can focus on capturing quality footage rather than worrying about battery swaps.

• They are suitable for fixed-position flights only.

• That means they are an ideal choice for limited surveillance without any disruption.

• They support long-duration monitoring by continuously exchanging data and energy with ground stations.

• Providing stable elevation at a specific location for hours, where a battery-powered drone can not work.
