Fibre Optic Tether for Drones & Robotics: Master RF-Denied Environments

Radio waves are fickle. They die underwater, get lost underground, and get bullied in congested airspace. For professionals, that's not a quirk; it's a critical point of failure. This fibre optic tether is the definitive solution for any environment hostile to RF. It provides a physically secure, high-bandwidth data link for robotics operating everywhere from subsea trenches and mine shafts to electronically contested battlefields.

Primary Applications

This isn't an upgrade; it's a fundamental capability for operators who can't gamble on RF. You need this if you are:

• Exploring Subterranean Spaces: For mapping mines, caves, or inspecting long pipelines, RF is a non-starter. This tether provides the kilometres of reliable, high-bandwidth connectivity needed to navigate and inspect complex GPS-denied environments from a safe distance.
• Deploying Underwater Robotics (ROVs): Seawater is where radio signals go to die. For any serious ROV work requiring clear, real-time video and control, a fibre tether is the non-negotiable industry standard. Get that crystal-clear 4K feed from the depths, lag-free.
• Operating in Contested Airspace: For C-UAS testing or missions in areas with active electronic warfare, this tether makes your data link invisible and immune. It provides a perfect "ground truth" baseline for testers and an unjammable link for operators.

Core Capabilities

• Total Environment Immunity: Whether the obstacle is a kilometre of rock, hundreds of metres of seawater, or a military-grade jammer, this fibre link provides a physically isolated, interference-proof channel.
• Massive Bandwidth: Easily handles multiple high-resolution video streams and complex telemetry, making it ideal for inspection-class robots and ISR drones.
• Critical Note: This is the fibre reel only. You need to supply your own air/sea/land and ground media converters to interface with your vehicle's systems.

Specifications

(We're listing the manufacturer's most detailed specs. Assume a standard margin of engineering optimism.)

• Cable Diameter: 0.26mm (Adds negligible drag in water, air, or long, dusty tunnels)
• Fibre Type: Single-mode (The professional standard for high-speed, long-distance data)
• 100M Spool: Just enough to test your setup and get your hopes up. (Size/weight negligible)
• 1KM Spool: W95*H65mm / 0.3KG
• 2KM Spool: W95*H125mm / 0.4KG
• 3KM Spool: W121*H246mm / 0.53KG
• 5KM Spool: W121*H246mm / 0.63KG (The most popular flavour of "are we there yet?")
• 10KM Spool: W121*H246mm / 1.0KG
• 15KM Spool: W147*H276mm / 1.5KG
• 20KM Spool: W147*H276mm / 1.8KG (At this point, you'll need a bigger backpack)
• 25KM Spool: W147*H276mm / 2.2KG
• 30KM Spool: W147*H276mm / 2.6KG (Because that pipeline isn't going to inspect itself)

What’s in the Box*

• 1x Spool of Pure Photonic Potential (in your chosen length)
• 1x A conspicuous absence of antennas

Disclaimer

*The box contains precisely one fibre optic reel. The engineering genius to implement it is sold separately (and we're pretty sure you've already got it).

Still Here?

Whether you're developing C-UAS tech, deploying a subsea ROV, or mapping a mine shaft, you've read this far because you know RF has hard limits. This tether is what lies beyond them. If your mission demands a data link that simply cannot fail, you've found your solution.
