Arduino Optical Fiber Data Transmission

In my setup for Arduino optical fiber data transmission, I’ve chosen to employ the Amplitude Shift Keying (ASK) scheme. This communication method allows two Arduinos to exchange information through an optical link. To make this work, I’m relying on the Radiohead Amplitude Shift Keying Library. This library serves as a handy tool, simplifying the implementation of ASK in my project, making the communication process between the Arduinos efficient and effective.

Arduino Optical Fiber : Bidirectional Communication

For bidirectional Arduino Optical Fiber communication, combining the transmitter and receiver into a single circuit creates a transceiver, streamlining data transfer. This transceiver excels in serial communication over optical fiber, supporting encoding schemes like Manchester, 4B5B, or 8B10B for enhanced reliability. The versatility extends further as it seamlessly interfaces with multiple protocols such as I2C, UART, RS232, and RS485. This adaptability makes the circuit an ideal choice for various applications, from simple point-to-point connections to complex networks. Its compatibility and flexibility empower Arduino enthusiasts to explore a spectrum of communication possibilities, making it an invaluable asset for advanced projects and applications.

Here is an Arduino Optical Fiber bidirectional communication example:

This demo shows how Arduino can send data through light cables. Two Arduinos talk to each other using UART, controlling a moving part and light intensity. I tested it and it worked well over a distance of 342 meters. I made some adjustments to the sending part, and everything still worked fine. You can get all the things you need, like the code and the models for sending and receiving, from this post. If you want to understand it better, there’s a video you can watch too. It’s like a simple chat between Arduinos using light!
