In 400G Ethernet data centers, HPC and machine learning clusters, the Arista Compatible 400G OSFP DR4 Optical Transceiver delivers 400Gbps transmission over SMF with a reach of 500m. With its MPO-12/APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on Arista Networks hardware, it is a drop-in equivalent of the OSFP-400G-DR4.

Compliance: CMIS 5.2, IEEE 802.3bs-400GAUI-8, OSFP MSA, IEEE 802.3 bs-400GBASE-DR4. For projects standardized on Arista Networks hardware, this product replaces the OSFP-400G-DR4 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

To order, quote OSFP-DR4-400G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
