In 400G Ethernet data center and cloud network environments, the Arista Compatible 400G QSFP-DD QDD LR4 Optical Transceiver delivers 425Gbps (4x 106.25Gbps) transmission over SMF with a reach of 10km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with Arista Networks platforms and replaces the Arista Networks part QDD-400G-LR4 directly.

This product is designed and tested to comply with QSFP-DD MSA HW Rev 5.1, QSFP-DD, CMIS Rev 5.0, IEEE 802.3cu, 100G Lambda MSA. It is interoperable with Arista Networks equipment and serves as a direct equivalent to the Arista Networks part number QDD-400G-LR4.

Our part number for this module is QDD-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.

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.

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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
