The 800G QSFP-DD QDD PC Passive DAC, 0.5m is a passive dac direct attach copper cable with QSFP-DD to QSFP-DD, supporting 800Gbps links over a length of 0.5m (2ft). 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 PC Passive DAC, 0.5m connects QSFP-DD to QSFP-DD ports at 800Gbps in 800G Ethernet data center and cloud network environments. This unit is produced in 3 standard lengths from 0.5m (2ft) to 1.5m (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
Compliance: QSFP-DD MSA, CMIS Rev4.0, IEEE 802.3ck. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
The factory part number is QDD-800G-PC. This cable is available in 0.5m (2ft), 1m (3ft) and 1.5m (5ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 30AWG. Volume pricing is available for project quantities.
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.
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
