800G QSFP-DD QDD PCxxx Passive DAC

For short reach 800Gbps links in 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD PCxxx Passive DAC offers a factory terminated passive dac assembly with QSFP-DD to QSFP-DD connectors and 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. The cable meets QSFP-DD MSA, CMIS Rev4.0, IEEE 802.3ck.

Applications
The 800G QSFP-DD QDD PCxxx Passive DAC connects QSFP-DD to QSFP-DD ports at 800Gbps in 800G Ethernet data center and cloud network environments. 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. The link runs 8x 100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.
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.
Packing Details
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
How We Ship
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.
Reliability Control
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.
