Applications
The Arista Compatible 400G OSFP LR4 Optical Transceiver is used in 400G Ethernet data centers, HPC and machine learning clusters, where it provides a 400Gbps link over SMF up to 10km. With its Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Compatibility with Arista Networks systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of OSFP-400G-LR4.
Standards and Compatibility
This product is designed and tested to comply with OSFP MSA, IEEE 802.3 bs-400GAUI-8, IEEE 802.3 cu, and CMIS4.0. It is interoperable with Arista Networks equipment and serves as a direct equivalent to the Arista Networks part number OSFP-400G-LR4.
Ordering Information
Our part number for this module is OSFP-LR4-400G. 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.
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.
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
