OSFP-400G-DR4: frequently asked questions
What is the Arista OSFP-400G-DR4?
The Arista OSFP-400G-DR4 is a OSFP 400GBASE-DR4 module from Arista Networks for 400 Gbps links. It plugs into a OSFP port on an Arista switch and is used for 400G spine and super-spine fabrics, AI/ML clusters, 4 × 100G breakout and data-centre interconnect.
What is the maximum distance of the OSFP-400G-DR4?
Arista specifies the OSFP-400G-DR4 for 500 m on parallel single-mode fiber (interoperates with 4 × 100GBASE-DR up to 500 m).
What are the transmit and receive power levels of the OSFP-400G-DR4?
Per Arista's published optics data sheet, the OSFP-400G-DR4 transmits −2.9 to +4.0 dBm/lane and receives −5.9 to +4.0 dBm/lane.
Which fiber and connector does the OSFP-400G-DR4 need?
The OSFP-400G-DR4 uses a 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 OSFP-400G-DR4 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 400G version do I need?
It depends only on your switch port. OSFP ports need OSFP optics and QSFP-DD ports need QSFP-DD optics; they are not mechanically interchangeable. If both ends run the same optical standard (e.g. DR4 to DR4), an OSFP module and a QSFP-DD module interoperate over the fibre.
Does the OSFP-400G-DR4 support breakout?
Yes. Arista lists breakout to 4 × 100G-DR. Use the matching optics at the far end and a suitable breakout cable or patch panel.
Is your OSFP-400G-DR4 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-400G-DR4 price in India and how do I order?
The Arista OSFP-400G-DR4 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-400G-DR4 draw?
Arista lists maximum power of 12 W for the OSFP-400G-DR4. Check your switch's per-port power budget for dense deployments.
