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.

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. The link runs 8x 100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

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.

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.

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.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.
