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. The Dual MTP/MPO-12 APC interface and 1310nm 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-800G-2XDR4. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.
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.
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.
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
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.
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
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.
