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. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.
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
Our part number for this module is QDD-DR4-400G. 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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Quality and Testing
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.
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.
