    1.6T Heterogeneous Interconnection – 1.6T OSFP224 DR8 PHO to 2×800G DR4 Heterogeneous Interconnection Solution

    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.
