The 800G QSFP-DD QDD PCxxx Passive DAC is a passive dac direct attach copper cable with QSFP-DD to QSFP-DD, supporting 800Gbps links over a length of 0.5~1.5m (2~5ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 800G Ethernet data center and cloud network environments, and complies with QSFP-DD MSA, CMIS Rev4.0, IEEE 802.3ck.

Product Highlights

• QSFP-DD to QSFP-DD
• Data rate: 800Gbps
• Cable type: Passive DAC
• Length: 0.5~1.5m (2~5ft)

In 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD PCxxx Passive DAC provides a factory terminated 800Gbps link between QSFP-DD to QSFP-DD ports. This unit is supplied at 0.5~1.5m (2~5ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

This product is designed and tested to comply with QSFP-DD MSA, CMIS Rev4.0, IEEE 802.3ck. It plugs into any standards-based QSFP-DD to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model is supplied at 0.5~1.5m (2~5ft) under part number QDD-800G-PCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 28~30AWG. Volume pricing is available for project quantities.

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.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.
