400G QSFP-DD QDD AExxx AEC

The 400G QSFP-DD QDD AExxx AEC 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. Cable length: 1m (3ft)~5m (16ft).

The 400G QSFP-DD QDD AExxx AEC connects QSFP-DD to QSFP-DD ports at 400Gbps 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 8x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards compliance covers QSFP-DD MSA, IEEE 802.3cd, CMIS 5.0. The unit works in any equipment with a standard QSFP-DD to QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

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.

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.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.

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.
