1.6T Heterogeneous Interconnect Solution –1.6T OSFP224 DR8 PHO TO 2X800G DR4

The 1.6T OSFP224 DR8 PHO module features FIBERSTAMP’s patented HYBRID architecture, supporting both VCSEL-based and silicon photonics–based implementations. By utilizing only half of the DSP channels compared to traditional full-DSP designs, the HYBRID architecture delivers lower power consumption, reduced latency, and improved system efficiency for next-generation AI and data center networks.

Inspired by LPO/LRO design methodologies and enhanced through system-level signal alignment, the HYBRID approach offers a balanced and scalable alternative, combining linear-drive efficiency with selective DSP functionality:

HYBRID = (LTO + LRO) / 2

Key Benefits:

  • Lower Power, Lower Latency: Optimized DSP usage significantly reduces power draw and end-to-end latency
  • System-Level Optimization: Improved signal integrity for large-scale AI and DC deployments
  • Cost-Efficient Scaling: Reduced BOM and operational costs for 800G and 1.6T networks

Target Applications:

  • Heterogeneous Network Architectures with Reduced Gearbox Dependency
  • 800G AI & Data Center Interconnects
  • 1.6T AI Clusters and Hyperscale Data Centers

As AI computing drives networks into the 1.6T era, hyperscalers are deploying 1.6T OSFP switches and 800G OSFP RHS server NICs to enable all-to-all GPU connectivity using two-layer fat-tree topologies.

FIBERSTAMP’s HYBRID optical solutions are engineered to support this transition with higher efficiency, better scalability, and lower total cost of ownership.
