Fiber-optic FPV — technical specification
AEROSCOPE T4 fibre-optic strike line: physical optical link replaces RF for command and video.
T4-F10 · T4-F15 · T4-F20 · T4-ML — product walkthrough
T4-F10 · Fiber Strike 10 km
| Parameter | Value | Notes |
|---|---|---|
| Optical fibre | G.657.A2 · 0.26 mm · 10.1 km | Sky-mounted spool; payout >50 N tension class |
| Sky module | 16–35 g · FC UPC | 1310/1550 nm · CRSF / ELRS bridge |
| Ground terminal | 29–65 g receiver | XT60 4–6S · BNC/RCA video out |
| Strike airframe | 10" carbon quad (T1 class) | Integrated spool mount · CG marked with warhead sim |
| Control path | Fibre only — no RF command | Immune to barrage jamming and RF direction-finding |
| Video path | Analog HD over fibre | <1 ms one-way latency typical |
| EW resistance | Full — physical link | GPS spoofing may still affect autopilot if fitted |
| Spool mass (sky) | ~1.0 kg incl. module | 101.6 mm × 351 mm drum class |
T4-F15 · Fiber Strike 15 km
Flagship fibre tier — 13" heavy quad base (T2 class) + 15.1 km spool. Recommended for anti-armour in dense EW.
T4-F20 · Fiber Strike 20 km
Maximum tactical fibre envelope — 20.1 km drum (~2.0–2.6 kg sky end). Single-use strike profile; fibre snaps on impact.
Optical module kit
Sky link + ground terminal — bidirectional light-pulse bridge. Compatible with ELRS / CRSF / SBUS / DJI TTL class hand controllers via GH1.25 data interface.
- Input power sky: 3.3–32 V DC or 3–6S battery
- Wavelength: 1310 nm / 1550 nm single-mode
- Attenuation budget: ~5–7 dB at 20 km — within commercial transceiver margin
- Operating temperature: −50 °C to +100 °C (industrial fibre class)
T4-ML · Mobile Fiber Launcher
Mobile unmanned ground vehicle relays fibre payout — same operational class as Dronobus / mobile fibre launcher programmes shown in global EW theatres. UGV tows or trails fibre; drone operates on air segment with hardwired C2. Runway-free deployment for QRF cells.
