Applications
Network architects choose the Arista Compatible 400G OSFP LR4 Optical Transceiver for 400G Ethernet data centers, HPC and machine learning clusters: it runs 400Gbps over SMF and reaches 10km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on Arista Networks hardware, it is a drop-in equivalent of the 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
Order this product as OSFP-LR4-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
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.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
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.
