Description

The Arista LPO-800G-2DR4 is a linear pluggable optics (LPO) 800G OSFP transceiver that runs as two independent 400GBASE-DR4 links over parallel single-mode fibre. It is built for short-reach data centre links up to 500m, such as leaf-spine connections, and a single 800G port can break out to two 400G DR4 links. It suits AI/ML and high-density 800G fabrics where optics power draw matters.

The module uses two MPO-12 APC connectors and operates at 1310nm over G.652 single-mode fibre, with a transmit power of -2.9 to +4.0 dBm and a receive power of -5.9 to +4 dBm per lane. With no DSP in the module, maximum power consumption is under 9W, compared with 16W for standard 800G OSFP optics. This dual MPO-12 2x DR4 variant differs from the LPO-800G-DR8, which uses a single MPO-16 connector, and the LPO-800G-2FR4, which uses two duplex LC connectors for 2km reach.

It is intended for OSFP 800G ports on Arista platforms that support LPO optics, and typical link partners are other 400GBASE-DR4 interfaces over parallel single-mode fibre with MPO-12 APC cabling.

FAQs

Q: How much power does this transceiver draw?
A: Maximum power consumption is under 9W. Standard non-LPO 800G OSFP optics are listed at 16W, so the LPO design reduces optics power per port.

Q: What cabling does it need?
A: It needs parallel single-mode fibre (G.652) terminated with MPO-12 APC connectors, one for each 400G DR4 link, with a maximum reach of 500m.

Q: Can it connect to 400G DR4 ports?
A: Yes. The module presents two 400GBASE-DR4 links, so each MPO-12 connector can link to a 400GBASE-DR4 interface over parallel single-mode fibre.

Q: Which ports does it work with?
A: It is designed for OSFP 800G ports on Arista platforms that support LPO optics. Check the Arista transceiver compatibility matrix for your specific switch model and software version.

Q: How does it differ from the LPO-800G-DR8 and LPO-800G-2FR4?
A: The LPO-800G-DR8 uses a single MPO-16 connector with 500m reach, while the LPO-800G-2FR4 uses two duplex LC connectors for 2km reach. This 2DR4 module uses dual MPO-12 connectors with 500m reach.
