Description

The LPO-800G-2DR4 is an 800G OSFP linear pluggable optics (LPO) transceiver built for high-density AI/ML and data centre spine-leaf links where lower power and latency matter. It carries two 400GBASE-DR4 links over parallel single-mode fibre, suiting 800G-to-2x400G breakout designs.

The module operates at 1310nm over SMF G.652 and reaches up to 500m. Two MPO-12 APC connectors give two independent 400G DR4 links. Power consumption is under 9W, compared with 16W for standard DSP-based 800G OSFP optics, because the host-side DSP handles signal processing. Transmit power is -2.9 to +4.0 dBm per lane and receive power is -5.9 to +4 dBm per lane.

The transceiver fits OSFP ports on Arista platforms that support 800G LPO optics and connects over parallel single-mode fibre to 400GBASE-DR4 interfaces. Check the Arista transceiver compatibility matrix for supported platforms.

FAQs

Q: What does LPO mean and how does it differ from a standard 800G OSFP optic?
A: LPO stands for linear pluggable optics. The module has no onboard DSP, as signal processing is handled by the host. This keeps module power under 9W, compared with 16W for standard DSP-based 800G OSFP optics.

Q: What fibre and connectors does it use?
A: It uses parallel single-mode fibre (SMF G.652) with two MPO-12 APC connectors, operating at 1310nm. The reach is up to 500m.

Q: Can it break out into two 400G links?
A: Yes. The two MPO-12 APC connectors each carry a 400GBASE-DR4 link, so the module supports 800G-to-2x400G breakout to 400GBASE-DR4 interfaces.

Q: Which switches support this module?
A: It fits OSFP ports on Arista platforms that support 800G LPO optics. Check the Arista transceiver compatibility matrix to confirm your platform and software release.

Q: How much power does it draw?
A: Maximum power consumption is under 9W per module, drawn from the host OSFP port.
