Arista LPO-800G-2DR4 Compatible OSFP-800LPO-2DR4 OSFP PAM4 Linear-drive Pluggable Optics (LPO) Transceiver for 7800R4/7060X6 Series Switch, Support 800GBASE-DR8 (SMF, 1310nm, 500m, Dual MTP/MPO-12 APC, DDM)
NADDOD OSFP-800LPO-2DR4 is a cost-effective module with high performance, which is optimized for AI Datacenter, supporting datarate of 8x112Gb/s PAM4 Optical interface and 8x112Gb/s PAM4 Electrical interface. Its transmission distance is up to 500m on single mode fibers. It replaces a retimed DSP data path with a linear data path, thus realizing lower power consumption and latency. It has been designed to withstand the maximum range of external operating conditions including temperature, humidity and EMI. The module offers very high functionality and feature integration, accessible via a two-wire serial interface. The transmitter driver AGC can be enabled or disabled, to increase dynamic range.
OSFP-800LPO-2DR4 adopts a DSP-free linear architecture, reducing power consumption by approximately 50% (8W vs. 16W) compared with conventional 800G retimed optics. This simplified design reduces transmission latency and improves link efficiency, while also optimizing TCO through reduced cooling, power consumption, and infrastructure requirements. Designed for large-scale AI training clusters, it offers broad compatibility with mainstream RoCE devices for stable and efficient deployment.
Tested on the Arista DCS-7060X6-64PE switch with all lanes in stable link-up status, achieving a pre-FEC bit error rate of 2.28E-13, demonstrating excellent signal integrity and reliable 800G transmission performance.
