400G QSFP-DD QDD AExxx AEC

The 400G QSFP-DD QDD AExxx AEC is a active dac (aec) direct attach copper cable with QSFP-DD to QSFP-DD, supporting 400Gbps links over a length of 1m (3ft)~5m (16ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with QSFP-DD MSA, IEEE 802.3cd, CMIS 5.0.

The 400G QSFP-DD QDD AExxx AEC is a 400Gbps active electrical cable for QSFP-DD to QSFP-DD connections in 400G Ethernet data center and cloud network environments. This unit is supplied at 1m (3ft)~5m (16ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. 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 is supplied at 1m (3ft)~5m (16ft) under part number QDD-400G-AExxx. Other lengths of the same assembly can be produced on request. Wire gauge: 28~32AWG.

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.

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.

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.

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.
