    Hybrid Architecture Equivalent Active Optical Cable Solutions– 400G / 800G / 1.6T OSFP224

    Overview

    GIGALIGHT’s 400G, 800G, and 1.6T OSFP224 Hybrid Architecture Equivalent Active Optical Cable (Hybrid AOC) products utilize GIGALIGHT’s patented Hybrid AOC technology, which can be implemented using either VCSEL-based or silicon photonics-based designs.

    Unlike traditional full-DSP optical modules, the HYBRID architecture employs DSP on only half of the channels, resulting in significantly reduced power consumption and latency. While HYBRID modules and AOCs draw on standard industry LPO/LRO design approaches, they provide a more advanced strategy for precise system-level signal alignment. The HYBRID design methodology can be conceptually represented by the formula: HYBRID = (LTO + LRO) / 2

    This patented approach is designed to enable a new paradigm for AI & DC interconnects at 800G and above 1.6T, focusing on reducing power consumption, latency, and cost.

    Key Product Highlights
