Overview
As a leader in optical interconnect technology, GIGALIGHT has successfully developed a comprehensive liquid-cooled interconnect product line, including immersed liquid-cooled optical modules, AOCs, and liquid-cooled extenders. These solutions are widely applicable to 5G fronthaul and the latest AI compute scenarios, covering 400G and 800G high-speed interconnect requirements and supporting data centers in moving toward low-carbon, high-density operations.
The liquid-cooled extender series further addresses the interconnect demands of high thermal-density data centers, enabling efficient and reliable connectivity in demanding environments.

Technical Highlights
- High-Speed Core: Supports extension up to 0.5m (0.3m for 800G), featuring GIGALIGHT’s patented “fish-shaped” design.
- Packaging Compatibility: Supports SFP112, QSFP28, QSFP-DD, OSFP, etc., covering 25G~800G and paving the way for 1.6T.
- Thermal Optimization: Integrated 1.5W silent fan inside the socket to enhance heat dissipation.
- Visual Monitoring: Equipped with indicator lights, ideal for frequent plug-and-play scenarios, effectively extending switch port lifespan.
