Arista 800G OSFP DR4 Optical Transceiver

The Arista 800G OSFP DR4 is a high-density optical transceiver implementing the OSFP form factor for 800 Gigabit Ethernet connectivity over dual-fiber duplex links. Operating at 800 Gbps per channel using PAM4 modulation across four 200G lanes, the DR4 variant supports distances up to 500 meters over single-mode fiber (SMF), making it ideal for intra-data center and campus interconnect scenarios where extended reach beyond short-reach optics is required.

Designed for next-generation AI cluster networking and 800G-capable switch architectures, this transceiver delivers the performance density required for training workloads, high-performance computing (HPC) clusters, and carrier-grade backbone upgrades. The OSFP form factor enables superior thermal management and port density compared to legacy transceiver packages.

The DR4 specification balances cost-efficiency with extended-range capability, supporting modern coherent DSP-based implementations that maximize signal integrity over installed fiber plant without requiring ultra-short-reach tradeoffs.

Ideal for

• AI model training cluster interconnects requiring 800G bandwidth with 500m intra-campus reach
• Data center switch-to-switch backbone links across multiple buildings on unified fiber infrastructure
• High-performance computing (HPC) cluster node interconnection with deterministic low-latency performance
• Carrier and cloud provider 800G network upgrades supporting hyper-scale data center expansions
• Research institution and national lab networking requiring high-speed bulk data transfers between facilities
• Enterprise storage fabric uplinks for petabyte-scale distributed storage systems
