Arista LPO-800G-DR8 | 800G OSFP DR8 LPO Transceiver, 1310nm, 500m SMF

Q: What is Linear Pluggable Optics (LPO) and how does it differ from traditional DSP-based transceivers?
A: LPO technology replaces on-board Digital Signal Processing (DSP) with linear amplifiers and equalization, shifting signal processing to the host ASIC. This reduces module power consumption by approximately 40-50%, lowers latency, and decreases cost compared to traditional retimed DSP-based modules, making LPO ideal for high-density AI and HPC data centers.

Q: Is the LPO-800G-DR8 compatible with my existing network switches?
A: Compatibility depends on your host switch ASIC's support for LPO modules, CMIS 5.0 management, and correct channel mapping. The LPO-800G-DR8 is designed for Arista 7000 Series switches and other platforms with 800G OSFP support. Always verify compatibility with your switch vendor and conduct interoperability testing before deployment.

Q: What type of fiber and connector does the LPO-800G-DR8 require?
A: This transceiver uses a single MPO-16 APC connector and requires parallel single-mode fiber (SMF) for 800GBASE-DR8 applications, supporting distances up to 500 meters. Standard OM4 or OM5 multimode fiber is not compatible with this module.

Q: Can the LPO-800G-DR8 be used in breakout configurations?
A: The LPO-800G-DR8 is designed for native 800G DR8 operation using 8 lanes of 100G PAM4. Breakout configurations depend on the host platform's support for lane mapping and may require specific firmware or cable assemblies. Consult Arista documentation or your network vendor for supported breakout modes.

Q: What are the power and cooling requirements for deploying LPO transceivers at scale?
A: LPO-800G-DR8 modules consume approximately 9W per port, compared to 16W for DSP-based 800G modules. This significant power reduction lowers cooling demand and operational costs in high-density deployments, enabling more sustainable and scalable data center infrastructure for AI and cloud workloads.
