Optical Signal Conversion Unit «ASTRALEXPRESS» (Optical RX + VTX Foxeer 5.8G 2.5W + RX 2.4G + Foxeer Lollipop 5.8G)

Brand: Astral Express
Category: Ground Relay Stations

The «ASTRALEXPRESS» ground control unit is designed for reliable and secure control of unmanned aerial vehicles via a fiber optic reel. The module combines an optical receiver (Optical RX), a VTX Foxeer 5.8G video transmitter with up to 2.5W power, a 2.4G receiver for control, and a Foxeer Lollipop 5.8G video receiver, providing flexibility in building a control and video transmission system.

Advantages of fiber optics: makes the system resistant to EW and SIGINT, ensures stable operation even in complex electromagnetic environments, allows for communication and video transmission over distances up to 30 km, significantly increasing the reliability and confidentiality of communication channels.

Device capabilities: allows operation in two modes (control and video transmitted via cables or radio channel); supports image transmission via RCA connectors for connecting additional monitors or recording; can receive control signals via the built-in ELRS 2.4 GHz receiver or directly from the equipment via cable, ensuring flexibility in setup and complete anonymity when using SIGINT countermeasures.

Key features:

• VTX 5.8 GHz (Foxeer) with switchable power and video channels, supporting Foxeer Lollipop 5.8G for video signal reception.
• VTX power: up to 2.5W, ensuring a stable signal in remote operation conditions.
• Power supply: compatible with Li-Ion 3–6S batteries, allowing flexible power source selection according to platform requirements.
• Control protocol: ELRS — stable control channel, cable control option for maximum security and anonymity.
• RCA outputs for image transmission — additional flexibility for integration with various equipment and recording systems.
• Fiber optic channel wavelength: 1310/1550 nm, ensuring optimal long-distance signal transmission and compatibility with modern fiber optic systems.

This unit is ideal for professional applications requiring a combination of high communication range, protection against active interference, and the ability to quickly switch operating modes (cable/radio). The module's configuration with VTX Foxeer 5.8G 2.5W and 2.4G and Foxeer Lollipop 5.8G receivers makes it a versatile solution for video relay and unmanned system control tasks in field conditions.
