Overview
The 400G QSFP-DD HYBRID VR8-AOC product adopts GIGALIGHT’s patented technology: the Hybrid Architecture Equivalent Active Optical Cable (Hybrid AOC) technology. Unlike conventional FULL DSP optical modules, the HYBRID series integrates DSPs on only half of the channels, which significantly reduces power consumption and latency.
It can be said that HYBRID optical modules and active optical cables draw on and adopt the industry’s general design methodology of LPO/LRO. Nevertheless, from the perspective of strict system signal alignment, HYBRID delivers a more advanced design strategy. The equivalent formula for the HYBRID design methodology can be simply interpreted as:HYBRID = (LTO + LRO) / 2.
By innovating traditional solutions with hybrid interconnection technology, this product serves as an upgraded replacement for 400G QSFP-DD VR8 AOC. It features low loss, high compatibility, and flexible deployment, caters to the high-density and low-cost interconnection requirements of data centers, and achieves simultaneous improvements in transmission performance and operational efficiency.
Technical Highlights
- Power consumption: 6.6W, achieving a 20%–25% reduction(vs. >10W for conventional 400G QSFP-DD AOC)
- Significant Cost Optimization: Approximately 21% lower overall cost compared with existing DSP-based solutions.
- Transmission distance: Up to 30m over OM3 multimode fiber (MMF) and 50m over OM4 MMF.
- Ultra-Low Link Latency: Link latency reduced by approximately 50% versus traditional DSP solutions.
- Superior Signal Quality: Designed to achieve a pre-FEC BER (Bit Error Rate) level of E-7/E-8 over 50m OM4 MMF links.
