Arista LPO-800G-2FR4 | 800G LPO Transceiver, 2km, Dual LC, 1310nm CWDM4

Q: What is the key advantage of LPO transceivers compared to standard 800G optics?
A: Linear Pluggable Optics (LPO) eliminates the power-intensive DSP retiming chip, reducing power consumption from 16W to just 9W per module. This 44% reduction in power draw significantly lowers data center operating costs and thermal management requirements while maintaining full 800G performance.

Q: Can this transceiver support breakout to 400G connections?
A: Yes, the LPO-800G-2FR4 supports 2x 400GBASE-FR4 breakout applications. Each of the two LC duplex connectors can operate independently at 400Gbps, allowing connection to two separate 400G FR4 modules without requiring breakout cables. This provides deployment flexibility for mixed-speed environments.

Q: What platforms support Arista LPO 800G transceivers?
A: Arista LPO 800G transceivers including the LPO-800G-2FR4 are supported on select Arista platforms with EOS 4.35.2 or later. Verify platform compatibility in the Arista Transceiver Compatibility Guide, as LPO support requires specific hardware capabilities including appropriate SerDes interfaces.

Q: Is this transceiver compatible with other vendors' 800G or 400G FR4 optics?
A: Yes, the LPO-800G-2FR4 follows industry-standard specifications (IEEE 802.3ck/cu, OSFP MSA) and interoperates with standards-compliant 800G 2xFR4 or 400G FR4 transceivers from other manufacturers. Each port uses standard CWDM4 wavelengths over SMF, ensuring multi-vendor compatibility.

Q: What cable type is required for this transceiver?
A: This transceiver requires OS2 single-mode fiber (SMF) patch cables with LC duplex connectors. The dual LC interface means you need two duplex LC-LC patch cables per module. Standard G.652 single-mode fiber supports transmission up to the rated 2km distance.
