Applications
The Arista Compatible 400G QSFP-DD QDD FR4 Optical Transceiver is used in 400G Ethernet data center and cloud network environments, where it provides a 400Gbps link over SMF up to 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. 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 QDD-400G-FR4.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA, CMIS.5.0, IEEE 802.3bs. It is interoperable with Arista Networks equipment and serves as a direct equivalent to the Arista Networks part number QDD-400G-FR4.
Ordering Information
Order this product as QDD-FR4-400G. 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.
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.
Custom-made Fiber Products
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.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight 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.
