The 3KM FPV Optical Fiber from Redpoint transmits video and control signals through a 0.26 mm fiber tether rather than radio frequency, reducing susceptibility to RF interference in congested electromagnetic environments. Designed for operators conducting short-range tactical missions, the system delivers low-latency analog video with bidirectional S.BUS control over a 3,100 m single-mode fiber line. The handheld reel weighs 0.48 kg and measures 94 mm × 445 mm, supporting portable deployment. Priced at 200 USD, the product is manufactured in an ISO 9001-certified facility with an annual output exceeding 100,000 units, and supports OEM and ODM customization as well as bulk orders for defense and industrial clients.
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. The integrated sky-end module mounts directly to the drone airframe and pays out fiber during flight. Redpoint advises operators to deploy the first 200 m of fiber at reduced speed to prevent damage.
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 for field diagnostics.
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. The ground unit offers both non-inverted and inverted S.BUS outputs to match different flight controller interfaces, simplifying integration with existing drone platforms.

The fiber-based link is suited for short-range reconnaissance in areas with active RF jamming, where conventional radio links may experience disruption. The tethered configuration maintains a continuous physical connection between the airframe and ground station.
Enterprise customers in infrastructure inspection, public safety, and site surveying can use the system for line-of-sight operations requiring a stable video downlink. The 3 km range covers typical urban and industrial site perimeters.
No. The ground unit requires an NP-F960, NP-F970, NP-F980, or NP-F990T battery, which must be sourced separately.
The ground module provides both non-inverted (OUT1) and inverted (OUT2) S.BUS outputs, compatible with flight controllers that support S.BUS input.
The fiber tether is a consumable component. Replacement reels are available, and Redpoint offers OEM and ODM support for enterprise customers requiring custom configurations.
Bulk pricing and minimum order quantities are available through direct inquiry. The factory maintains an annual production capacity exceeding 100,000 units to support volume orders.
