LPO-800G-2DR4: frequently asked questions
What is the Arista LPO-800G-2DR4?
The Arista LPO-800G-2DR4 is a OSFP 2 × 400GBASE-DR4 (linear pluggable) module from Arista Networks for 800 Gbps links. It plugs into a OSFP port on an Arista switch and is used for 800G AI/ML back-end fabrics, hyperscale spine layers and 2 × 400G / 8 × 100G breakout.
What is the maximum distance of the LPO-800G-2DR4?
Arista specifies the LPO-800G-2DR4 for 500 m on parallel single-mode fiber (2 × 400G-DR4).
What are the transmit and receive power levels of the LPO-800G-2DR4?
Per Arista's published optics data sheet, the LPO-800G-2DR4 transmits −2.9 to +4.0 dBm/lane and receives −5.9 to +4 dBm/lane.
Which fiber and connector does the LPO-800G-2DR4 need?
The LPO-800G-2DR4 uses a 2 × MPO-12 APC connector on parallel single-mode (G.652), at 1310 nm. APC connectors have an angled (green) end-face, so use APC patch cords and trunks. Both ends of the link must use the same optical standard.
Is the LPO-800G-2DR4 compatible with my Arista switch?
It works in Arista switches with OSFP ports that support this optic. Arista lists it as supported on specific platforms only. Send us your switch model and EOS version and we will check it against Arista's Transceiver and Cable Guide before dispatch, so you only receive a module that works in your port.
What is an Arista LPO (linear pluggable optic)?
LPO modules drop the DSP inside the optic and let the switch drive the lasers directly. Arista lists them at under 9 W versus 16 W for a standard 800G optic, cutting power and latency in large AI / cloud fabrics. They need an LPO-supported Arista platform.
Does the LPO-800G-2DR4 support breakout?
Yes. Arista lists breakout to 2 × 400G-DR4. Use the matching optics at the far end and a suitable breakout cable or patch panel.
Is your LPO-800G-2DR4 genuine Arista?
Yes. Next Gen Networks supplies original Arista Networks optics, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch, and we share the serial numbers on request so you can verify them in EOS ('show inventory').
What is the LPO-800G-2DR4 price in India and how do I order?
The Arista LPO-800G-2DR4 price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
How much power does the LPO-800G-2DR4 draw?
Arista lists maximum power of < 9 W for the LPO-800G-2DR4. Check your switch's per-port power budget for dense deployments.
