Anti interference fiber drum

Our company independently develops and produces fiber optic anti-interference devices, which can solve signal free scenarios and are not affected by electromagnetic interference. They are suitable for drones, unmanned ships, unmanned boats, and underwater robots. The products are divided into two series: ordinary fiber optic devices and high-end fiber optic devices. The biggest advantage of fiber optic anti-interference devices is that they transmit control signals and data through fiber optic communication technology, rather than traditional radio waves.

Specification

System Composition

The fiber optic anti-interference communication system consists of three parts: fiber optic transmitter, transmitter, and receiver, which can achieve real-time bidirectional information exchange between the mobile carrier end and the control end. It can support multiple communication modes such as Ethernet, serial port, TTL, HDMI, etc.
