800G QSFP-DD QDD PCxxx Passive DAC

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)

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). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. 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.

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.

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.

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.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
