Description

The Arista LPO-800G-2FR4 is an 800G linear pluggable optics (LPO) transceiver in the OSFP form factor, built for high-density data centre and AI/cloud spine and leaf links over duplex single-mode fibre. It sits in Arista's 800G LPO family and omits the onboard DSP, which keeps module power draw low on every port.

The module carries two independent 400GBASE-FR4 links, 2x 400G-FR4, in a single 800G OSFP package using the 1271, 1291, 1311 and 1331 nm CWDM4 wavelengths. Connectivity is via two duplex LC connectors over SMF G.652 single-mode fibre, with a reach of up to 2km. Maximum power consumption is below 9W, compared with 16W for a standard DSP-based 800G 2FR4 OSFP module. Per-lane transmit power is -3.2 to +4.4 dBm and receive power is -7.2 to +4.4 dBm.

It fits OSFP cages on Arista platforms that support linear pluggable optics. Sibling modules in the family are the LPO-800G-2DR4 (dual MPO-12, 500m) and LPO-800G-DR8 (MPO-16, 500m), so this is the duplex LC, 2km option.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What fibre and connectors does this module use?
A: It uses two duplex LC connectors over single-mode fibre (SMF G.652), with a maximum reach of up to 2km.

Q: How much power does the LPO-800G-2FR4 draw?
A: Maximum power consumption is below 9W. The linear pluggable design omits the onboard DSP, whereas a standard DSP-based 800G 2FR4 OSFP module draws 16W.

Q: Which platforms support this transceiver?
A: It fits OSFP cages on Arista platforms that support linear pluggable optics. Check Arista's Transceiver and Cable Guide for the supported platform list.

Q: How does it differ from the LPO-800G-2DR4 and LPO-800G-DR8?
A: The LPO-800G-2FR4 uses duplex LC connectors and reaches up to 2km. The LPO-800G-2DR4 uses dual MPO-12 and the LPO-800G-DR8 uses MPO-16, both with a 500m reach.

Q: Can it break out into two 400G links?
A: Yes. The module carries two independent 400GBASE-FR4 links, 2x 400G-FR4, within the single 800G OSFP package.
