I/O Testing Tools

    GrowsFiber provides a series of I/O testing tools (loopback, MCB and checker) for high-speed optical transceiver modules and interconnect cables that are used in data center server/switch networks.

    I/O Testing for High-Speed Interconnects

    The recent rapid growth in data center traffic and cloud computing has resulted in a massive increase in machine-to-machine traffic due to the rapid adoption of server virtualization, software-defined networking (SDN), and cloud computing. Now, add the massive amounts of bandwidth required to train terabyte-scale data networks for training (GPU)-based artificial intelligence (AI) machine learning (ML) systems.

    This drives huge demand for high bandwidth and low latency networks. High-speed DACs and AOCs, as well as optical transceiver module interconnections, play a key role in these modern data center technologies.
