Transceiver Cisco Compatibile OSFP-800LPO-2DR4 OSFP PAM4 Linear-drive Pluggable Optics (LPO), supporto 800GBASE-DR8 (SMF, 1310nm, 500m, Dual MTP/MPO-12 APC, DDM)
NADDOD OSFP-800LPO-2DR4 è un modulo ad alte prestazioni e conveniente, ottimizzato per Data Center AI, con interfaccia ottica 8x112Gb/s PAM4 ed elettrica 8x112Gb/s PAM4. Distanza di trasmissione fino a 500m su fibra monomodale. Sostituisce il percorso dati DSP con uno lineare, riducendo consumo e latenza. Progettato per resistere a condizioni operative esterne estreme (temperatura, umidità, EMI). Funzionalità avanzate accessibili via interfaccia seriale a due fili. AGC del driver di trasmissione attivabile/disattivabile per aumentare la gamma dinamica.
In large-scale AIDC deployments, LPO technology eliminates the DSP chip from optical modules, significantly reducing system power consumption and latency while improving energy efficiency.
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.
