UART Fiber Optic Transceiver Module With 2 Mbps Data Transmission And 10 km Communication Distance
The Gravity UART Fiber Optic Transceiver Module is a high-performance communication solution designed for long-distance, high-speed serial data transmission in industrial, automation, and embedded applications. Unlike traditional shielded twisted-pair communication systems that are susceptible to electromagnetic interference and signal degradation, this module uses optical fiber technology to provide complete electrical isolation and highly reliable communication over distances up to 10 km. The module supports UART serial communication and maintains stable data transmission at speeds up to 2000000 baud.
With built-in immunity to electromagnetic interference, lightning protection capability, and support for installation alongside high-power electrical cables, the module is ideal for harsh industrial environments. It can also be used with passive optical splitters to create one-to-many star network topologies, providing flexible deployment options for industrial monitoring, remote control systems, data acquisition networks, and automation projects. Its Gravity-compatible design ensures simple integration with Arduino, ESP32, Raspberry Pi, and other embedded platforms.
