Accelink OSFP112 800G DR8 LPO Linear-drive Pluggable Optical Module (500 m, ≤7.5 W)

Product Overview

The Accelink OSFP112 800G DR8 LPO implements 800 Gbit/s as eight 112G-class lanes using linear direct-drive (LPO) optics: the DSP is removed and retiming is handled by the host switch SerDes with strong FEC, per the LPO MSA 100G-DR-LPO v1.01 specification (published 2025-03-19) built on OIF CEI-112G-LINEAR-PAM4. Accelink’s OIF demo document specifies 500 m reach at 1310 nm, 0-70°C operation, and power consumption of ≤7.5 W for LPO (≤9.5 W for the RTLR/LRO variant).

Compared with conventional 800G DSP modules at roughly 14-18 W, the ≤7.5 W LPO budget cuts module power by roughly half, which matters at AI-cluster scale where thermal and power envelopes limit switch density; industry analyses place LPO modules at 6-9 W versus 14-18 W for DSP designs in the 800G class.

Typical applications include power-constrained 800G leaf-spine tiers in AI clusters, ≤500 m in-hall fabrics where the host switch supports linear lanes, and operators seeking to reduce per-link thermal load while the 200G/lane and LPO ecosystem matures.

• 800G DR8 LPO: 8×112G linear-drive lanes, no DSP retiming
• ≤7.5 W module power (LPO) vs ≤9.5 W RTLR/LRO per OIF/Accelink OFC2025 document
• 500 m reach at 1310 nm, 0-70°C, dual MPO-12/MPO-16 connectors
• Aligned with LPO MSA 100G-DR-LPO v1.01 (2025-03-19) and OIF CEI-112G-LINEAR-PAM4
• Roughly half the power of conventional 800G DSP modules (industry analyses)
