Overview
The Accelink 1.6T OSFP224 DR8 is a next-generation pluggable optical transceiver purpose-built for AI and machine-learning data center fabrics. It doubles the per-module bandwidth of 800G optics to 1.6 Tbps across eight 200G PAM4 lanes, matching the 224G SerDes class of current 102.4 Tbps switch silicon.
Its 3nm DSP paired with a silicon-photonics optical engine cuts module power versus earlier 5nm designs, easing the thermal bottleneck of dense AI rack deployments. Accelink also offers a 1.6T O-band Coherent-Lite OSFP-XD variant reaching up to 20 km for campus DCI, and a single-wavelength 200G VCSEL variant for ultra-high-speed short-reach links.
Key Benefits
Bandwidth density: 1.6T per port over 8x200G PAM4. Power efficiency: 3nm DSP + SiPh reduce consumption at high density. Scale-out ready: OSFP1600 MSA and IEEE 802.3dj compliance for 102.4T switch platforms.
Applications
AI/ML training and inference clusters, hyperscale and cloud data centers, 1.6T Ethernet and InfiniBand scale-out fabrics, campus DCI (Coherent-Lite variant).
