Description

The Arista LPO-800G-2FR4 is a Linear Pluggable Optics (LPO) OSFP transceiver designed for high-performance data centers and AI workloads. It delivers 800G throughput over dual duplex single-mode fiber up to 2km, using CWDM4 wavelengths (1271nm, 1291nm, 1311nm, 1331nm) and PAM4 modulation. This twin-port transceiver enables seamless 800G to 2x 400G FR4 breakout applications without additional breakout cables, offering significant power savings compared to traditional optics. Ideal for spine-leaf architectures, switch-to-switch interconnects, and hyperscale data centers.

FAQs

Q: What is Linear Pluggable Optics (LPO) and what are the benefits?
A: LPO transceivers eliminate the need for onboard DSP (digital signal processing) chips by performing signal processing in the host switch ASIC. This results in significantly lower power consumption, reduced heat generation, lower costs, and improved reliability compared to traditional DSP-based optics—ideal for large-scale hyperscale and AI data center deployments.

Q: Can this transceiver be used in 800G to 2x 400G breakout applications?
A: Yes, the LPO-800G-2FR4 is designed specifically for this use case. It interoperates with two separate 400G-FR4 OSFP or QSFP-DD transceivers via two single-mode fiber duplex patch cables, enabling flexible connectivity without requiring breakout cables. Each port can operate at 400G independently.

Q: Which Arista switches support the LPO-800G-2FR4 transceiver?
A: The LPO-800G-2FR4 is supported on Arista 7800 and 7060X6 Series switches (including the 7060X6-64PE and 7060X6-32PE models) running EOS version 4.35.2 or later. Always check Arista's transceiver compatibility matrix for the latest platform support details.

Q: What is the maximum transmission distance for this transceiver?
A: The LPO-800G-2FR4 supports link distances up to 2km over OS2 single-mode fiber using dual duplex LC connectors. It is optimized for inter-rack and cross-row data center connectivity.

Q: Is this transceiver hot-swappable and does it support digital diagnostics?
A: Yes, the LPO-800G-2FR4 is hot-swappable and supports DDM/DOM (Digital Diagnostics Monitoring) via CMIS 5.0, allowing real-time monitoring of parameters such as optical power, temperature, bias current, and voltage for proactive network management.
