In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD AOxxx AOC provides a factory terminated 400Gbps link between QSFP-DD to QSFP-DD ports. Ordered in customized lengths, it matches the actual rack geometry without slack. 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.

Compliance: IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA,QSFP-DD-CMIS-rev4p0. 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.

This cable is built to order in customized lengths. Our part number QDD-400G-AOxxx identifies the configuration. When placing an order, tell us the length you need and any label or packaging requirements. Samples for testing can be arranged before bulk orders.

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.

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.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
