Overview
GIGALIGHT’s 1.6T OSFP224 DR8 PHO(Pluggable Hybrid Optics) SiPh Module adopts the company’s patented Hybrid Architecture Equivalent technology. This patent is designed to work with both VCSEL and silicon photonics-based architectures, offering a flexible approach to next-generation high-speed links.Unlike conventional full-DSP optical modules, the Hybrid series integrates DSP on only half of the channels, thus achieving significant improvements in power consumption and latency reduction.
In essence, Hybrid optical modules and active optical cables draw on the industry’s general design methodologies for LPO/LRO. However, from the perspective of strict system signal alignment, Hybrid technology delivers a more advanced design strategy.The equivalent formula for the Hybrid design approach can be simply understood as:Hybrid = (LTO + LRO) / 2.
It’s core objective is to create a brand-new, more advantageous technical pathway in terms of power consumption, latency, and cost, catering to 800G AI&DC interconnection, as well as 1.6T and higher-rate AI&DC systems.
Technical Highlights
- AI/ML-Driven: In response to the explosive growth of AI computing power, networks are evolving toward the 1.6T era!
- Key Breakthroughs: Addressing the power consumption and efficiency challenges posed by branch interconnection and Gearbox in 1.6T/800G heterogeneous networks.
- Objective: Enabling the construction of more efficient and cost-effective large-scale AI/ML data centers.
Application Scenarios
Leading AI enterprises have launched 1.6 Tbit/s switches supporting OSFP packaging and 800Gbit/s OSFP-RHS (Riding Heat Sink) packaged server fiber network cards, enabling 10,000-GPU cluster interconnection through a two-tier fat-tree network topology.
