The 20KM FPV Optical Fiber from Redpoint transmits video and control signals through a 0.26 mm fiber tether, eliminating reliance on radio frequency links in environments with high electromagnetic interference. Built for professional operators requiring medium-range penetration, the system delivers low-latency HD analog video with bidirectional S.BUS control over a 20,100 m single-mode fiber line. The compact reel weighs 1.7 kg and measures 133 mm × 484 mm, balancing extended range with field portability. Priced at 915 USD, the product is manufactured in an ISO 9001-certified factory with an annual output exceeding 100,000 units, and supports OEM and ODM customization as well as bulk orders for defense and industrial clients worldwide.
The tether uses G657A2 bend-insensitive single-mode fiber with a Resin/PVC outer jacket, rated for tensile loads above 50 N. Optical attenuation is specified at ≤2 dB at 1550 nm and ≤3 dB at 1310 nm, maintaining signal integrity across the full 20.1 km span. The integrated sky-end module mounts to the drone airframe and pays out fiber during flight. Redpoint advises operators to deploy the first 200 m at reduced speed to protect the fiber.
The Opticallink GBD-MAX ground module features an aluminum alloy shell measuring 123 mm × 56 mm × 31 mm and weighing 186 g ± 2 g. It provides an FC optical fiber interface, a BNC video output, a GH1.25 data port, and an XT60 3-6S external power input. The unit accepts NP-F960, NP-F970, NP-F980, or NP-F990T batteries; the battery is not included. Four LED indicators display power, fiber link, video, and data status, enabling field diagnostics without additional test equipment.
The system supports NTSC, PAL, and SECAM analog video formats with bidirectional data at rates up to 1 Mbps. Wavelength division multiplexing uses 1310 nm and 1550 nm channels over a single fiber, and the GBD-MAX module supports transmission distances up to 60 km on single-mode fiber. The ground unit offers both non-inverted and inverted S.BUS outputs to accommodate different flight controller interfaces.

The 20.1 km fiber link supports extended reconnaissance and perimeter surveillance in contested RF environments. The physical tether maintains a continuous connection between the airframe and ground station where radio links may be denied or degraded.
Enterprise customers managing power grids, pipelines, and border infrastructure can deploy the system for long-corridor inspection. The extended range reduces the number of ground station relocations required across large operational areas.
No. The ground unit requires an NP-F960, NP-F970, NP-F980, or NP-F990T battery, which must be sourced separately.
Operators should deploy the first 200 m at reduced speed. The fiber is rated for tensile loads above 50 N, but consistent payout speed is recommended to prevent snags or breakage over the full 20.1 km length.
The fiber tether is a consumable component. Replacement reels are available, and the sky-end module can be transferred to a new reel for continued operations.
Redpoint supports OEM and ODM customization, including branding and configuration adjustments. Bulk pricing and lead times are available through direct inquiry, supported by an annual production capacity exceeding 100,000 units.
