OSFP-800G-VSR8: frequently asked questions
What is the Arista OSFP-800G-VSR8?
The Arista OSFP-800G-VSR8 is a OSFP 800GBASE-VSR8 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 OSFP-800G-VSR8?
Arista specifies the OSFP-800G-VSR8 for 30 m on OM3 and 50 m on OM4 parallel multimode fiber, single MPO-16 connector.
What are the transmit and receive power levels of the OSFP-800G-VSR8?
Per Arista's published optics data sheet, the OSFP-800G-VSR8 transmits −4.6 to +4 dBm/lane and receives −6.3 to +4 dBm/lane.
Which fiber and connector does the OSFP-800G-VSR8 need?
The OSFP-800G-VSR8 uses a MPO-16 APC connector on parallel multimode (OM3/OM4), at 850 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 OSFP-800G-VSR8 compatible with my Arista switch?
It works in Arista switches with OSFP ports that support this optic. 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.
OSFP vs QSFP-DD: which 800G version do I need?
Pick the form factor that matches your Arista switch port. Arista offers 800G platforms in both OSFP and QSFP-DD variants; modules with the same optical standard interoperate over the fibre, but are not mechanically interchangeable.
Is your OSFP-800G-VSR8 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 OSFP-800G-VSR8 price in India and how do I order?
The Arista OSFP-800G-VSR8 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 OSFP-800G-VSR8 draw?
Arista lists maximum power of 16 W for the OSFP-800G-VSR8. Check your switch's per-port power budget for dense deployments.
