800G & 1.6T FRO High-Speed Optical Modules

“Computing power determines the ceiling; interconnectivity determines survival.” As the scale of AI computing clusters continues to grow, the interconnect bandwidth and density that “determine survival” are also rising accordingly. In today’s AI computing centers, 51.2T switches, particularly the 64×800G configuration, are becoming the new standard for primary switching nodes due to their high bandwidth and density, leading to the widespread adoption of 800G optical modules. With the introduction of 102.4T switches, the optical communications industry is already gearing up for the wave of 64x1.6T solutions. Stable and reliable 1.6T optical modules are crucial for ushering in a new era of optical interconnect.

Based on industry needs, Luxshare-Tech has comprehensively deployed a variety of optical module solutions, including FRO, LRO, and LPO, to fully cover all speed specifications. Luxshare-Tech’s 800G and 1.6T FRO high-speed optical module series adopt the OSFP packaging format, focusing on core high-speed interconnect requirements, with distinct emphases on transmission types and technical configurations to precisely match different application scenarios.

Emphasizing exceptional value and broad compatibility, these modules offer multiple transmission choices of DR8, 2xDR4, and 2xFR4, which can provide flexibility and adaptability for various transmission scenarios. The are currently the main product for general-purpose interconnects in data centers.
