400G QSFP-DD QDD AOxxx AOC

The 400G QSFP-DD QDD AOxxx AOC connects QSFP-DD to QSFP-DD ports at 400Gbps over OM4 fiber at 850nm. Because the optics are built into the cable ends, installation is plug and play with no separate transceivers to manage, and airflow inside the rack stays unobstructed. It is well suited to 400G Ethernet data center and cloud network environments. Cable length: Customized.

The 400G QSFP-DD QDD AOxxx AOC is a 400Gbps active optical cable for QSFP-DD to QSFP-DD connections in 400G Ethernet data center and cloud network environments. Ordered in customized lengths, it matches the actual rack geometry without slack. 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. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.

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. Volume pricing is available for project quantities.

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.

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.

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
