Immersion Liquid-Cooling Optical Extender Solutions for High-Density Optical Networks

FIBERSTAMP’s Immersion Liquid-Cooling Optical Extender Solutions extend liquid-cooling interconnect technology to optical extenders, enabling reliable, low-power optical connectivity in high-heat-density environments such as AI compute clusters, hyperscale data centers, and 5G fronthaul applications. These extenders work alongside immersion liquid-cooled optical modules and active optical cables to support future-ready interconnects from 25G up to 800G and pave the way toward 1.6T deployments.

Solution Highlights

  • High-Speed Extension: Supports up to 0.5 m extension for most rates and up to 0.3 m for 800G links, ensuring stable performance across short optical paths.
  • Broad Compatibility: Works with major pluggable form factors including SFP112, QSFP28, QSFP-DD, OSFP, and others — covering optical rates from 25G to 800G and laying groundwork for future 1.6T solutions.
  • Thermal Optimization: Integrated 1.5 W silent fan in the extender socket enhances heat dissipation for stable, continuous operation in thermally demanding systems.
  • User-Friendly Design: Built-in visual indicators simplify plug-and-play use and help protect switch ports for long-term system reliability.

Product Portfolio

FIBERSTAMP’s extender series includes a range of high-speed liquid-cooling extenders for:

  • 100G (QSFP28) — up to 0.5 m
  • 200G (QSFP56) — up to 0.5 m
  • 400G (QSFP-DD) — up to 0.5 m
  • 800G (QSFP-DD) — up to 0.3 m

Additional variants and future options span up to OSFP-RHS and 1.6T-compatible formats.

Typical Applications

  • Immersion liquid-cooled data center interconnects
  • 5G fronthaul networks
  • High-density optical switching platforms

By combining liquid cooling extensibility with broad form-factor support, this solution enables efficient heat management, high-speed optical transmission, and reliable plug-and-play deployment for modern high-performance networks.
