Immersion Liquid Cooling Solutions

    Learn about immersion liquid cooling optical transceivers, active optical cables (AOC) and direct-attach copper cables (DAC).

    GrowsFiber’s immersion cooling optical transceiver integrates a fiber optic pigtail on the optical port side of the module. The module adopts super air-tight packaging technology and can be immersed in a depth of 1 meter. It is the most efficient data center server/switch high-speed interconnection solution.

    GrowsFiber’s immersion cooling optical transceivers are widely used in data centers adopting liquid-cooling heat dissipation methods, including multi-mode and single-mode series. Among them, the transmission distance of the former can reach up to 100 to 400 meters; the latter can reach up to 2 to 10 kilometers.

    Designed by the GIGALIGHT R&D team and manufactured by GrowsFiber’s Yancheng factory, each immersion cooling optical transceiver has undergone strict pressure testing and performance testing to meet the use environment of immersion cooling and provide the best cooling performance for liquid-cooled data centers.

    Superior Cooling Efficiency, Performance and Reliability

    GrowsFiber is perfect for the most demanding immersion liquid cooled data centers by testing each immersion cooling optical module in real liquid-cooled usage scenarios to ensure optimum air tightness and end-to-end performance server/switch network.

    GrowsFiber’s immersion liquid-cooled modules mainly include two series of multi-mode and single-mode, which provides a very comprehensive range of options in terms of data rate, modulation, form factor and pigtail type, and supports one-stop shopping for liquid-cooled data centers.

    • Data rates of 25Gb/s to 200Gb/s
    • Modulations of 25G NRZ and 50G PAM4
    • Form factors of SFP28, QSFP28 and QSFP56
    • Pigtail types of LC, FC and MPO/MTP

    Note: The liquid cooling technology used in GrowsFiber’s immersion liquid-cooled optical modules has obtained a patent certificate, which is held by the parent company of GIGALIGHT.

    Low Cost, Low Power, High Performance and High Reliability

    GrowsFiber’s immersion liquid-cooled optical modules are manufactured using GIGALIGHT’s self-developed immersion liquid cooling technology, which supports the operating temperature range of 0-60 degrees Celsius in an immersion liquid cooling environment. Due to the ultra-high heat dissipation efficiency of the immersion liquid cooling, it provides the best operating environment for the optical module, and the actual energy consumption is also smaller than that of the ordinary optical module, which saves both the energy consumption cost and the heat dissipation cost for the data center.

    At the same time, GrowsFiber’s immersion liquid-cooled optical modules have undergone very strict reliability tests, which can provide lower bit error rates and higher signal integrity.

    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.
