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.

Compliance: QSFP-DD MSA HW Rev 7.0, CMIS Rev 5.0, IEEE802.3cu-2021, IEEE802.3ck-2022. For projects standardized on Arista Networks hardware, this product replaces the QDD-800G-2XDR4 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Our part number for this module is QDD-XDR8-800G. 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.

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.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

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.

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.
