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.

Applications
The 800G QSFP-DD QDD PCxxx Passive DAC is an 800Gbps direct attach copper cable for QSFP-DD to QSFP-DD connections in 800G Ethernet data center and cloud network environments. This unit is supplied at 0.5~1.5m (2~5ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
Standards compliance covers QSFP-DD MSA, CMIS Rev4.0, IEEE 802.3ck. The unit works in any equipment with a standard QSFP-DD to QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
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.
Our Testing Process
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.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
Customization Service
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.
Logistics
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.
