Applications
In 400G Ethernet data center and cloud network environments, the Arista Compatible 400G QSFP-DD QDD DR4 Optical Transceiver delivers 425Gbps (4x106.25Gb/s) transmission over SMF with a reach of 500m. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Compatibility with Arista systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QDD-400G-DR4.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA HW Rev 5.1, QSFP-DD CMIS Rev 5.0, IEEE 802.3bs. It is interoperable with Arista equipment and serves as a direct equivalent to the Arista part number QDD-400G-DR4.
Ordering Information
Order this product as QDD-DR4-400G. 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.
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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all 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.
