15KM FPV Optical Fiber

Overview of 15KM FPV Optical Fiber

The Redpoint 15KM FPV Optical Fiber is a tethered fiber-optic video and data transmission system built for professional operators requiring extended-range, interference-free drone connectivity. By routing HD video and bidirectional flight control through a 0.26mm physical fiber tether, the system eliminates RF jamming and signal-interference vulnerabilities associated with conventional wireless FPV links. The reel carries 15100m of G657A2 bend-insensitive single-mode fiber, weighing 1.25kg with exterior dimensions of 105mm×445mm. A sky-end module is integrated directly into the reel housing. The 15km configuration is designed for medium-range reconnaissance, perimeter surveillance, and inspection operations that demand both reach and resistance to electromagnetic disruption.

Transmission Performance of 15KM FPV Optical Fiber

The system uses wave length-division multiplexing at 1310nm and 1550nm across a single-mode single-fiber path. Light attenuation is measured at ≤2dB at 1550nm and ≤3dB at 1310nm over the full 15100m cable length. Composite video output conforms to NTSC, PAL, and SECAM standards for compatibility with standard FPV displays and recorders. Bidirectional data transmission runs at 0 to 1Mbps via S.BUS protocol, carrying flight control commands ground-to-air and telemetry air-to-ground simultaneously. The 0.26mm diameter fiber cable carries a tensile rating above 50N. The ground module draws power from an XT60 connector supporting 3-6S lithium packs or from an NP-F series battery dock, with an aluminum alloy shell measuring 123mm×56mm×31mm and weighing 186g±2g.

Deployment and Connection of 15KM FPV Optical Fiber

The ground module supports two connection configurations. Wireless Mode 1 pairs the Opticallink GBD unit with an external video receiver and RC receiver. Wired Mode 2 connects the GBD unit directly to an RC transmitter and monitor through the video output interface. The aircraft-mounted sky-end module links to the flight controller via the FC optical fiber port, with video input handled through the VGPGG5TR connector. OUT1 outputs non-inverted S.BUS and OUT2 outputs standard inverted S.BUS; select the channel matching the flight controller S.BUS input specification. Prior to deployment, remove the four protective clips and transport cable ties, then extract the carbon fiber retaining rod. Clean the FC connector with a fiber-optic cleaning pen before mating. Operation is not recommended when optical attenuation exceeds -15dBm. The first 200 meters should be paid out at reduced speed to prevent fiber stress or breakage.

Industrial Applications of 15KM FPV Optical Fiber

The 15KM FPV Optical Fiber is used by defense and security units, border patrol agencies, energy infrastructure inspectors, telecommunications tower survey teams, and large-scale industrial facility operators requiring extended-range, jamming-resistant video and control links. Production is ISO 9001 certified with annual output exceeding 100,000 units, enabling OEM, ODM, and bulk order fulfillment for commercial users and enterprise customers globally.

FAQ About 15KM FPV Optical Fiber

What is included in the 15KM FPV Optical Fiber package?

The package includes the 15100m fiber reel with integrated sky-end module, the Opticallink GBD ground module, a BNC power cable, and a video receiver module. A battery compatible with NP-F960, F970, F980, or F990T standards powers the ground module but must be purchased separately.

Can the 15KM FPV Optical Fiber work with my existing flight controller?

The system connects to flight controllers with an FC optical fiber port. Both non-inverted S.BUS (OUT1) and inverted S.BUS (OUT2) outputs are provided to match the input configuration of supported flight controllers.

What is the maximum operational range?

The reel contains 15100m of fiber. The ground module supports single-mode transmission up to 60km, so the 15100m cable length is the limiting factor for operational radius.

How do I verify link status during flight?

LED indicators on the sky-end and ground-end modules display power (PWR, red), fiber connection (LINK, orange), video signal (VIDEO, blue), and data signal (DATA, green), providing real-time status confirmation.
