Dell NVIDIA 400Gbps Single-port OSFP 400Gb/s single mode DR4 Transceiver – 1N8TG

Dell NVIDIA 400Gbps OSFP 400GBASE-DR4 Single-Mode Transceiver — 1N8TG

The Dell 1N8TG is a 400Gbps single-port OSFP (Octal Small Form-factor Pluggable) transceiver supporting the 400GBASE-DR4 standard over single-mode fiber. Designed for use with NVIDIA (Mellanox) ConnectX and Spectrum switch platforms, this transceiver delivers ultra-high-bandwidth connectivity for hyperscale data centers, AI/ML clusters, and high-performance computing fabrics. With a reach of up to 500m over SMF, it bridges top-of-rack and end-of-row switching with exceptional signal integrity.
