VaporConnect Optical Feedthrough Modules

As data centers face demands for increasing speed and capacity to meet the needs of AI and machine learning applications, two-phase immersion cooling helps manage thermal challenges to high-performance computing systems. VaporConnect Optical Feedthrough Modules connect optical transceivers inside the cooling tank to cabled infrastructure outside the tank via a versatile, reliable and upgradeable sealed module to support immersion cooling solutions.

Features and Benefits


As AI-driven demands for more capacity compel data centers to upgrade their capabilities, effective thermal management becomes increasingly crucial. One compact and efficient solution for keeping the temperature low in high-performance servers is two-phase immersion cooling. These systems require specialized, reliable connectivity solutions that reduce assembly errors and component failures. Data centers also need flexible and cost-effective interconnect solutions that optimize space and support future upgrades.

VaporConnect Optical Feedthrough Modules help make two-phase immersion cooling easier and more cost-effective by enabling data centers to scale and upgrade capabilities without redesigning the immersion tank itself. The modules are rigorously tested before shipment for sealing performance, helping ensure dependable operation. They are also available with customizable footprints and connector options to meet customer specifications.

With VaporConnect Optical Feedthrough Modules, data centers can save money by using efficient immersion cooling with reliable and flexible components that offer simplified installation and reduced system downtime. The VaporConnect system also offers greater flexibility to customize connectivity solutions, saving design time and money while streamlining future upgrades.

Fully Sealed for Two-Phase Immersion Cooling Applications

VaporConnect Optical Feedthrough Modules come with a sealing gasket and are thoroughly tested using industry-standard helium-leak testing. This ensures a reliable and robust seal with the tank wall to enable a seamless transition from the server line cards inside the tank to the cabling infrastructure outside the tank.

Flexible Form Factor Options Streamline Upgrades

The module is designed to support a range of industry-standard or Molex optical connector form factors, including MTP, LC and very small form factor (VSFF) options such as MMC, MDC, SN and SN-MT. This ensures conformance to existing infrastructure and enables upgrades to newer or higher-density connectors without replacing the entire cooling tank.

Shuffle-Ready Modules Minimize External Patching

Molex FlexPlane technology can integrate complex routings into the VaporConnect Optical Feedthrough Module, reducing the need for patching and shuffling outside the module and simplifying installation.


Delivers flexibility and scalability for streamlining upgrades
With a range of optical connector options available to mix and match, data centers can benefit from customized module functionality and can easily upgrade to newer or more dense connectors without changing the tank architecture.

Minimizes external patching and shuffling requirements
Using Molex FlexPlane technology, the module can integrate complex fiber-routing options, reducing the need for shuffling outside the module.

Ensures a reliable seal for two-phase immersion cooling
Modules are rigorously tested using helium-leak testing to ensure a reliable and durable seal for use in the vapor zone of the immersion cooling tank, delivering secure and reliable connectivity and reducing the risk of failures.

Optimizes space through the use of customizable form factors
The module footprint can be customized to specific customer and application needs, helping enable higher density and improving cost efficiencies.
