Applications
Network architects choose the Arista Compatible 800G QSFP-DD QDD XDR8 Optical Transceiver for 800G Ethernet data center and cloud network environments: it runs 850Gbps (8x 106.25Gbps) over SMF and reaches 2km. With its Dual MTP/MPO-12 APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. 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-800G-2XDR4.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA HW Rev 7.0, CMIS Rev 5.0, IEEE802.3cu-2021, IEEE802.3ck-2022. It is interoperable with Arista Networks equipment and serves as a direct equivalent to the Arista Networks part number QDD-800G-2XDR4.
Ordering Information
Order this product as QDD-XDR8-800G. 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.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
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.
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.
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.
