400G QSFP-DD to 4 x 100G QSFP28 Active Optical Breakout AOC

The 400G QSFP-DD to 4 x 100G QSFP28 Active Optical Breakout AOC connects QSFP-DD to 4x QSFP28 ports at 400Gbps over Breakout AOC 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

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. One port becomes 4x QSFP28, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs QSFP-DD-8x 50G-PAM4 QSFP28-4x 25G-NRZ modulation, which keeps it aligned with current 400G switch silicon.

Compliance: QSFP-DD MSA, SFF-8661, IEEE802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, CMIS 4.0, SFF-8636. 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.

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.

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.

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.
