Built for 800G Ethernet data center and cloud network environments, this QSFP-DD module carries 850Gbps (8x 106.25Gbps) over SMF up to 2km per link. With its Dual Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QDD-2X400G-FR4.

Compliance: IEEE 802.3cu-2021, IEEE 802.3ck-2022, QSFP-DD MSA HW Rev 6.01, CMIS Rev 5.0. For projects standardized on Cisco hardware, this product replaces the QDD-2X400G-FR4 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.

Order this product as QDD-2FR4-800G. 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.

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.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

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.
