The 400G QSFP-DD to 4 x 100G QSFP28 Active Optical Breakout AOC connects QSFP-DD to 4x QSFP28 ports at 400Gbps in 400G Ethernet, data center interconnect and 5G transport networks. Ordered in customized lengths, it matches the actual rack geometry without slack. By fanning one port out to 4x QSFP28, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. 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 QSFP-DD-8x 50G-PAM4 QSFP28-4x 25G-NRZ modulation, which keeps it aligned with current 400G switch silicon.

This product is designed and tested to comply with QSFP-DD MSA, SFF-8661, IEEE802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, CMIS 4.0, SFF-8636. It plugs into any standards-based QSFP-DD to 4x QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This cable is built to order in customized lengths. Our part number QDD-400G-4Q4xNAOxxx identifies the configuration. When placing an order, tell us the length you need and any label or packaging requirements.

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.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.

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.
