400G QSFP-DD QDD AE AEC

The 400G QSFP-DD QDD AE AEC, 5m is an active optical cable assembly with QSFP-DD to QSFP-DD, carrying 400Gbps over Active DAC (AEC) at 850nm. Factory terminated and tested as a complete link, it offers a lighter and more flexible alternative to discrete transceivers with patch cords for 400G Ethernet data center and cloud network environments. Standard production lengths cover 1m (3ft) to 5m (16ft).

In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD QDD AE AEC, 5m provides a factory terminated 400Gbps link between QSFP-DD to QSFP-DD ports. This unit is supplied in 4 standard lengths from 1m (3ft) to 5m (16ft). 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. The link runs 8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Compliance: QSFP-DD MSA, IEEE 802.3cd, CMIS 5.0. 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 model carries part number QDD-400G-AE. You can order this assembly in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Non-standard lengths can be produced on request. Wire gauge: 28AWG. Volume pricing is available for project quantities.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.

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.

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.
