800G QSFP-DD QDD PC Passive DAC, 0.5m
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
In 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD PC Passive DAC, 0.5m provides a factory terminated 800Gbps link between QSFP-DD to QSFP-DD ports. This unit is delivered in 3 standard lengths from 0.5m (2ft) to 1.5m (5ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. 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
The ordering part number is QDD-800G-PC. We make this cable in 0.5m (2ft), 1m (3ft) and 1.5m (5ft). Special lengths outside this range can be produced to order. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
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.
