400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m
The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m is an active optical cable assembly with QSFP-DD to 4x QSFP28, carrying 400Gbps over Breakout AOC at 850nm. Factory terminated and tested as a complete link, it offers a lighter and more flexible alternative to discrete transceivers with patch cords for 400G Ethernet, data center interconnect and 5G transport networks. You can order standard lengths from 1m (3ft) to 20m (66ft).

Applications
Designed for 400G Ethernet, data center interconnect and 5G transport networks, the 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AOC, 3m carries 400Gbps between QSFP-DD to 4x QSFP28 interfaces. This unit is delivered in 8 standard lengths from 1m (3ft) to 20m (66ft). The breakout design lets one high speed port feed 4x QSFP28, which raises port utilization and simplifies cabling in dense rows. 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.
Standards and Compatibility
Standards compliance covers QSFP-DD MSA, SFF-8661, IEEE802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, CMIS 4.0, SFF-8636. The unit works in any equipment with a standard QSFP-DD to 4x QSFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
The ordering part number is QDD-400G-4Q4XNAO. We make this cable in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft) and 20m (66ft). Special lengths outside this range can be produced to order. Samples for testing can be arranged before bulk orders.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
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.
Reliability Control
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.
How We Pack
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.
