Applications
Designed for 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD to 4 x 100G QSFP56 Active Optical Breakout AOC carries 400Gbps between QSFP-DD to 4x QSFP56 interfaces. Ordered in customized lengths, it matches the actual rack geometry without slack. One port becomes 4x QSFP56, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. 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 QSFP56-2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA, QSFP-DD-CMIS-Rev4.0, SFF-8024, IEEE 802.3bs Annex120E. 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.
Ordering Information
This cable is built to order in customized lengths. Our part number QDD-400G-4QAOxxx identifies the configuration. When placing an order, tell us the length you need and any label or packaging requirements. Samples for testing can be arranged before bulk orders.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all 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.
Quality and Testing
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.
