Arista Compatible 400G OSFP LR4 Optical Transceiver

The Arista Compatible 400G OSFP LR4 Optical Transceiver is a OSFP (IHS/Finned Top) optical transceiver delivering 400Gbps over SMF. Operating at 1271nm, 1291nm, 1311nm, and 1331nm with a Duplex LC/UPC interface, it reaches 10km and is compliant with OSFP MSA, IEEE 802.3 bs-400GAUI-8, IEEE 802.3 cu, and CMIS4.0. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in 400G Ethernet data centers, HPC and machine learning clusters.

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. The Duplex LC/UPC interface and 1271nm, 1291nm, 1311nm, and 1331nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. 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.

On the compatibility side, this unit is the practical equivalent of the Arista Networks part OSFP-400G-LR4 and works in Arista Networks systems out of the box. Standards compliance covers OSFP MSA, IEEE 802.3 bs-400GAUI-8, IEEE 802.3 cu, and CMIS4.0.

To order, quote OSFP-LR4-400G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

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.
