The Arista Compatible 400G OSFP FR4 Optical Transceiver is used in 400G Ethernet data centers, HPC and machine learning clusters, where it provides a 400Gbps link over SMF up to 2km. With its Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Arista Networks platforms and replaces the Arista Networks part OSFP-400G-FR4 directly.

On the compatibility side, this unit is the practical equivalent of the Arista Networks part OSFP-400G-FR4 and works in Arista Networks systems out of the box. Standards compliance covers OSFP MSA 5.1,CMIS 4.0,IEEE 802.3cu,IEEE 802.3bs.

Our part number for this module is OSFP-FR4-400G. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.
