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

• QSFP-DD to 4x QSFP28
• Data rate: 400Gbps
• Cable type: Breakout AOC
• Length: Customized
• Wavelength: 850nm
• DDM/DOM: Supported

Designed for 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD to 4 x 100G QSFP28 Active Optical Breakout AOC carries 400Gbps between QSFP-DD to 4x QSFP28 interfaces. 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. Samples for testing can be arranged before bulk orders.

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.

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.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
