400G QSFP-DD to 4 x 100G QSFP56 Active Optical Breakout AOC

The 400G QSFP-DD to 4 x 100G QSFP56 Active Optical Breakout AOC connects QSFP-DD to 4x QSFP56 ports at 400Gbps over OM3 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 interconnect and 5G transport networks. Cable length: Customized.

Product Highlights

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.

Standards compliance covers IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA, QSFP-DD-CMIS-Rev4.0, SFF-8024, IEEE 802.3bs Annex120E. The unit works in any equipment with a standard QSFP-DD to 4x QSFP56 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 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.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

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.
