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. The Duplex LC/UPC interface and 1271nm,1291nm,1311nm,1331nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Arista Networks hardware, it is a drop-in equivalent of the OSFP-400G-FR4.
Standards and Compatibility
This product is designed and tested to comply with OSFP MSA 5.1,CMIS 4.0,IEEE 802.3cu,IEEE 802.3bs. It is interoperable with Arista Networks equipment and serves as a direct equivalent to the Arista Networks part number OSFP-400G-FR4.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Tested Before Shipment
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.
How We Pack
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.
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.
