Arista LPO-800G-2DR4-Arista | 800G OSFP 2xDR4 LPO Transceiver, 1310nm, 500m SMF

Q: What is Linear Pluggable Optics (LPO) technology?
A: LPO transceivers replace traditional Digital Signal Processing (DSP) with a linear data path using Transimpedance Amplifiers (TIA) and high-linearity drivers. This results in significantly lower power consumption (40-50% reduction), reduced latency, and lower cost compared to DSP-based transceivers, making them ideal for large-scale AI and hyperscale data centers.

Q: Which Arista switches support the LPO-800G-2DR4 transceiver?
A: The LPO-800G-2DR4 is supported on Arista 7060X6 Series switches (including 7060X6-64PE, 7060X6-64PE-B, and 7060X6-32PE) running EOS version 4.34.0 or later. These platforms feature OSFP ports optimized for 800G and support for LPO optics.

Q: Can this transceiver operate at lower speeds?
A: Yes, OSFP ports on compatible Arista switches support breakout configurations, allowing operation at 800G, 400G, 200G, or 100G speeds depending on platform capabilities and configuration, providing deployment flexibility.

Q: What fiber type and distance does this transceiver support?
A: The LPO-800G-2DR4 is designed for single-mode fiber (SMF) with dual MPO-12 APC connectors, supporting transmission distances up to 500 meters, making it suitable for intra-data center and campus interconnects.

Q: Is the LPO-800G-2DR4 compatible with standard 400G infrastructure?
A: Yes, the 2xDR4 twin-port design allows each of the two 400G channels to connect to separate 400GBASE-DR4 modules or endpoints using standard 12-fiber MPO patch cords, enabling seamless integration with existing 400G fiber infrastructure and migration paths to 800G.
