FPV Optical Fiber Image & Data Module (SKY/GBD) — Single-Mode 0–20 km, TTL/S.BUS, GH1.25

Overview

The Fiber Optic Image Digital Module (OPTICALLINK series) creates a wired, long-range, interference-immune link for drones and robots. Using single-mode fiber and FC connectors, it carries bidirectional image & control data (NTSC/PAL/SECAM; TTL / S.BUS) over 0–20 km without RF congestion, enabling reliable communication indoors, underground, or in EMI-heavy areas. A lightweight SKY module mounts on the vehicle; the GBD (ground-end) module includes a 7.4 V 6600 mAh Li-ion power pack. Typical scenarios include indoor inspection drones, pipe-crawling robots, underwater robotics, and remote fixed-site monitoring.

Key Features

• 0–20 km single-mode fiber link for high-stability, long-distance communication

• Strong anti-interference & anti-eavesdropping characteristics of optical media

• Bidirectional data; supports TTL / S.BUS control and NTSC/PAL/SECAM video formats

• Compact aluminum housings (airborne SKY and ground GBD) for robust deployment

• GH1.25 data interface, FC fiber interface, wavelengths 1310 nm (9/125 µm) + 1550 nm

• Optional ultra-light fiber “disk” spools for 1 km / 3 km / 5 km cable lengths

Model / Options (as shown)

• OPTICALLINK GBD-40KM (Black)

• OPTICALLINK SKY-40KM (Black) — without CNC

• OPTICALLINK GBD-80KM (Black)

• OPTICALLINK SKY-80KM (Black) — without CNC

Note: “40 km / 80 km” designations are model names; the illustrated single-mode working distance is 0–20 km. Choose SKY (airborne) and GBD (ground-end) to form a complete link, and select fiber length to suit your task.

Typical Applications

• Indoor/underground inspection drones where RF signals are blocked

• Pipeline/pipe-crawling robots needing stable, long-haul data backhaul

• Underwater robotics requiring EMI-free, long-distance tethered comms

• Remote industrial monitoring in high-EMI environments (e.g., substations)

What to Know Before Ordering

• Contents may vary by option (SKY module, GBD module, and fiber cable may be listed separately). Please confirm included items and required cable length before purchase.

• Ensure power and interfaces match your flight controller / robot (GH1.25; TTL/S.BUS).

• For airborne use, check payload capacity against the SKY module and chosen cable spool weight.
