DFRobot Gravity UART Fiber Optic Transceiver Module
The Gravity UART Fiber Optic Transceiver Module is a revolutionary solution for anyone struggling with traditional shielded twisted pair cables for remote signal transmission.
This advanced fiber optic communication module eliminates the need to reduce baud rates for transmission stability, consistently operating at 2000000 baud within distances up to 10km. The module provides complete electrical isolation, effectively preventing electromagnetic interference that commonly affects copper-based communication systems.
With its built-in lightning protection, this UART transceiver module offers superior reliability and safety, even in environments prone to electrical surges and can share cable trunking with strong power lines without signal degradation.
What makes this module particularly valuable is its ability to deliver interference-free communication at half the price of traditional shielded twisted pair solutions.
The Gravity: UART Fiber Optic Transceiver Module uses single-mode fiber with an SC interface operating at 1310nm wavelength, ensuring optimal performance in various applications.
It can be paired with a passive optical splitter to create one-to-many star networking configurations, making it incredibly versatile for complex communication systems.
Whether you're working on industrial automation, remote sensing, or any project requiring reliable long-distance data transmission, this module provides a cost-effective solution that overcomes the limitations of conventional copper-based communication methods while maintaining signal integrity across considerable distances.
