Optical Overdrive: DIY PCIe Connectivity via Fiber Optics
This hardware engineering project demonstrates a method for transmitting raw PCIe signals over optical fiber using standard SFP modules. Unlike typical external GPU setups that utilize Thunderbolt or USB4 encapsulation, this DIY approach focuses on a direct physical layer link to reduce overhead and latency. By designing custom interface boards, the project successfully bridges the distance gap for high-speed components, offering a unique solution for modular computing and specialized hardware setups while exploring the limits of high-frequency signal integrity.
