The 400G QSFP-DD QDD AE AEC, 5m connects QSFP-DD to QSFP-DD ports at 400Gbps over Active DAC (AEC) 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. The standard length range runs from 1m (3ft) to 5m (16ft).

Applications
The 400G QSFP-DD QDD AE AEC, 5m 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 produced in 4 standard lengths from 1m (3ft) to 5m (16ft). 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 8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA, IEEE 802.3cd, CMIS 5.0. It plugs into any standards-based QSFP-DD to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The factory part number is QDD-400G-AE. This cable is available in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.
Reliability Control
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.
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.
Customization Service
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.
Delivery
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.
