Applications
In 400G Ethernet data centers, HPC and machine learning clusters, the Arista Compatible 400G OSFP FR4 Optical Transceiver delivers 400Gbps transmission over SMF with a reach of 2km. With its Duplex LC/UPC 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-FR4. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
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.
Ordering Information
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.
Shipping and Lead Time
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
