NVIDIA VCSEL-based Active Fiber Cable

The NVIDIA MFS1S00-H030V is a 30-meter active optical cable designed to deliver high-speed data transfer for demanding InfiniBand HDR environments. It connects systems using QSFP56 connectors on both ends and supports a total bandwidth of 200Gb/s by combining four multi-mode fiber transceivers, each capable of 50Gb/s through PAM4 modulation. This makes it ideal for data centers that require reliable, long-distance connections without sacrificing speed.

Built with a VCSEL-based design, the cable ensures efficient optical transmission over multi-mode fiber, maintaining signal integrity across its extended length. It features a standard SFF-8665 QSFP56 electrical interface and offers selectable retiming on each lane, which helps optimize signal quality and performance depending on the setup. The cable operates on a single 3.3V power supply and typically consumes 5.0W per end, balancing power efficiency with high throughput.

Its hot-pluggable capability allows for easy installation and replacement without shutting down systems, which is crucial in environments where uptime is critical. Additionally, the cable supports I2C-based management through the SFF-8636 interface, enabling monitoring and control for better system integration and maintenance. Overall, this cable is well-suited for data centers and high-performance computing setups that need dependable, high-bandwidth connections over longer distances.
