Applications
In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD PCxxx Passive DAC provides a factory terminated 400Gbps link between QSFP-DD to QSFP-DD ports. It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
Standards compliance covers industry MSA standards. 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 standard length under part number QDD-400G-PCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 30AWG for 0.5/1/1.5m, 28AWG for 2m, 26AWG for 2.5/3m.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are 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.
